Sykes paper is a clarion call for higher standards for cryptozoology

The highly anticipated paper from B. Skyes regarding DNA testing of anomalous primates has been published and is, thankfully, freely accessible.

In 2012, the team from University of Oxford and the Museum of Zoology, Lausanne, put out a call for samples of suspected anomalous primates – Yeti, Bigfoot/Sasquatch, Almasty, orang pendek. The samples, if accepted, would be genetically tested using a cleaning method previously vetted in the Journal of Forensic Science that removes all traces of surface contaminants (most likely human) to get to the original DNA sequence. A specific portion of the DNA was used – the ribosomal mitochondrial DNA 12S fragment – for comparison to sequences in the worldwide genetic database GenBank.

A total of 57 samples were received. Two samples were actually not animal hair: one was plant material, the other was glass fiber. Those not trained in biology/zoology cannot always tell the difference between organic and inorganic matter or plant vs animal fibers, as we’d also seen from hunters collecting samples on the Spike TV show Million Dollar Bigfoot Bounty.
37 of the sample were selected for genetic analysis. 18 were from 8 U.S. states, including pairs from AZ, CA, MN, OR, TX. The rest were from WA, what is believed to be the prime habitat of Bigfoot/Sasquatch. 8 samples were anticipated to be the almasty from Russia. Three samples were collected in the Himalayan region of Asia and one came from Sumatra supposedly representing the orang pendek.

Let’s see what the results were.

Unfortunately, there were no anomalous primates in the lot. The sequences all matched 100%, there were no “unknowns”.

One was found to be human – from Texas. That only one matched with humans is a testament to the rigorous cleaning method that removed contamination. Sykes revealed his thinking about Melba Ketchum’s paper by noting that human contamination often “confounds the analysis of old material and may lead to misinterpretation of a sample as human or even as an unlikely and unknown human x mammalian hybrid” (Ketchum, et al.). Therefore, her claim of rigorous forensic procedures is shot down, again. Incidentally, Sykes et al. does not consider Ketchum’s paper as a “scientific publication” likely because it was self-published. The Sykes et al. study is regarded as the FIRST serious study regarding anomalous primate DNA – he cites two others that were joke papers. Recall that Ketchum cited these in her paper as genuine, revealing her professional ineptness. While the Sykes, et al. paper lists Ketchum as a reference, it is only to cite it as a poor study, not within the valid body of scientific literature, with misinterpreted results. [Burn.] The quality difference between the two papers is remarkable. The Sykes paper is readable and understandable with minimal jargon and a clear presentation of the data and conclusions. Ketchum’s paper was gobbledygook and, with this new commentary on it, albeit subtle, is another death-blow to any further serious scientific consideration.

All the U.S. samples turned out to be extant (already existing in that area) animals such as cow, horse, black bear, dog/wolf, sheep, raccoon, porcupine, or deer. There very clearly was nothing anomalous at all.

All the Russian samples, at least some of which were collected by Ketchum associate Igor Burtsev, also were disappointing. There were two anomalies, however. Samples of raccoon and American black bear were among the Russian samples indicating either a mistake in the location of the samples or individuals of these animals were imported to Russia at some point and their samples left behind.

Sadly, the orang pendek sample from Sumatra turned out to be from a Malaysian Tapir. This is not the first time tapirs have faked evidence for a Bigfoot creature. But I suspect this sample was very disappointing since the orang pendek is considered to be a plausible cryptid – likely a new species of primate. However, this test failed to provide support for that idea.

The Nepal sample turned out to be a native goat, a serow. However, the other two Himalayan samples were the most interesting of all.

Not one but two samples, those from Ladakh, India and Bhutan, matched a fossilized genetic sample of Ursus martimus, a polar bear of the Pleistocene era, 40,000 years old. Note: TWO samples! There was not a match with the modern species of polar bear. Thus, the study has discovered a new anomaly! This result is a boon to bear studies. Future research will continue to look for more evidence of the representative animal, hopefully a living one. The paper is clear, as was the documentary on this discovered which aired months ago, this previously unknown hybrid bear may contribute to the yeti legend. The look and behavior are reportedly different from the other native bears. Is the Yeti a bear? Well, the yeti is a very general term and its description varies across the huge expanse of the world where it is reported to exist. Even the orang pendek, more akin to an orang utan, is sometimes referred to as a “yeti”. Therefore, the “yeti” is likely not just one animal. It is feasible that this new bear constitutes one version of the yeti. Sykes has been open in stating that it does not mean a primate Yeti is not out there. It just means this result was not supportive of that idea.

Rendition of unknown bear that may represent the Yeti

The main thrust of this paper hits the gut of cryptozoology. As it is practiced today by amateur Bigfoot hunters and monster trackers, it is not science. This paper represents science. It’s a high bar. I’ve said as much before. To do science requires very specific training. One result of the Ketchum fiasco and the Sykes “success” has been to educate cryptid hunters about genetics and reliable tests that can give them the results they desire. This project was an excellent example of amateurs working with professionals – exactly what needs to be done to make real discoveries and come up with better answers than “It’s a squatch”.

sasquatch

I’ve always disputed the claim from paranormal researchers (including cryptozoology enthusiasts) that science ignores their work. Scientists had previously been involved in the founding of the field of cryptozoology but also studies in the psychical research and UFOs. They looked, there was nothing there and they moved on. (See my thesis on amateur research and investigation groups, ARIGs)

Now, the modern field of cryptozoology has been put on notice. You need to raise the standards; you need to stop wasting effort. Blurry pictures or another FLIR recording of a warm blob is not going to constitute worthwhile evidence. We best learn about nature through a scientific process. That means amateurs must work WITH the experts, not rail against them.

I was very pleased with the results of the Sykes, et al. study. I look forward to his book release on this topic as well.

Warnings of impending danger: Science and Social Factors

This is a paper I prepared for an ethics graduate class and have updated (7-June-2014). I present it in conjunction with a Strange Frequencies Radio podcast appearance on Sunday June 8.

Natural disasters happen every day. The people who can help prepare society for them are not psychics or crank pseudoscientists but those who study events inside out and upside down – scientists. Those who consider prediction a part of their research and responsibility range from weather forecasters to seismologists and volcanologists.

It’s a great responsibility to be tasked warning officials and the public about probable natural disasters. Warnings of impending danger cause predictable social and economic effects that must be considered along with achieving the primary goal, which is safety and minimizing loss of life. If a disaster prediction is wrong, several million people might be unnecessarily affected (Olsen, 1989 p. 107) and the region may suffer economic losses. If it is correct, but delivered inadequately, disaster is inevitable.

Accuracy of predictions is based on what is possible to observe and data that can be collected. For example, hurricane predictions are very accurate because scientists have extensive weather instruments and well-tested forecasting techniques to use. Volcanic hazard areas and shorelines prone to tsunamis are mapped based on zones identified through historical records – scientists can find geologic evidence that the land was affected by lava, ash or debris flows or inundated with waves of debris.

For many predicted events (volcanic eruptions, hurricanes, floods, blizzards), there is time to deliver the message and adequately prepare for the event. The worst situation is certainly earthquakes. There are no widely accepted precursors for quakes. Reliable prediction are long-term and large-scale — relatively unhelpful for preparation. With the potential for large seismic events to kill huge numbers of people, earthquake prediction theories have been particularly problematic and fraught with ethical dilemmas for the scientific community, public authorities and media.

It’s important to distinguish between predictions from the scientific community and those arising from the nonscientific community (pseudoscientific speculation, psychics and cranks). Scientific predictions must be supported by background theory and data and withstand skeptical scrutiny to be considered credible. The foundation mechanisms, explanations, calculations and assessments are expected to have gone through the gauntlet of peer review in order to gain acceptance. If the foundation is valid, then short-term, specific predictions will be credible. Predictive successes that have followed the conventional route include volcanic evacuations (Mt. St. Helens, Mt. Pinatubo in the Philippines, and the island of Montserrat) and severe weather alerts. Psychic and pseudoscientific predictions are not supported by theory or data and are not credible. I’ll not be addressing the ethics of those predictions as they are in a whole other realm.

Failed predictions fall on an impact scale from low (creating public inconvenience) to high (massive death tolls) with economic losses and potential career destruction in between. The following are some notable examples that highlight the major pitfalls inherent in predicting (or ignoring predictions of) natural disasters.

The Brady-Spence Debacle

In 1976, Dr. Brian Brady, a U.S. government scientist, made a specific prediction for a huge seismic event to take place in Lima, Peru in July of 1981. While the prediction itself was remarkably detailed, the theory supporting it was completely opaque (Olsen, 1989 p. 41). Brady’s theory had not been tested or published for peer review. During the lead up years to the event, things got complicated. Egos, priorities, agendas and protocol hijacked opportunities for proper, coherent, scientific critique. Peruvian officials and the public were confused by the lack of a reliable feed of information. The unstable political situation at the time led Peruvian citizens to think that their government was using the prediction to continue military control (Olsen, 1989 p. 131; Sol & Turan, 2004). The predicted quake did not occur. But, widespread disorder, decline of tourism, decrease in property values, and general public unrest resulted in an estimated economic damage in Lima of $50 million (Mileti & Fitzpatrick, 1993 p. 55).

The lack of following scientific protocol led to the situation getting out of hand. This episode is an example of a loss of objectivity by the chief scientist, the failure of the scientific community to address a serious situation in a coordinated way, and government agencies accepting rumors and pursuing misguided agendas without accurate information.

Armero

In 1985, Columbian scientists knew that villages in the valleys around the Nevado del Ruiz volcano were prone to disaster from eruptions. Yet, money was not allotted by the government to monitor the active volcano. The data that could be collected was ignored or not taken seriously by officials. When the media reported that an eruption would produce deadly mudflows that would obliterate the village of Armero, civic leaders called these press reports “volcanic terrorism”.

Church leaders added to the propaganda by telling people of the village not to fear. The poor population made no preparations to evacuate. Inevitably, the volcano erupted. That night, those who attempted to evacuate did not know where to go. Civil defense tried to get people out of the town but many refused to go – telling rescuers they were certainly mistaken. 23,000 people perished when a flood of meltwater and warm mud buried the town. Armero no longer exists, bodies were incased in dozens of feet of debris.

Government inaction in this entirely preventable situation was devastating. The situation was a heartbreaking testimony to the vulnerability of the poor to manipulation by authority  (Bruce, 2001).

Browning’s New Madrid prediction

Iben Browning was a scientist with unconventional ideas who took his claim directly to the media who gave it wide coverage. He pronounced that an earthquake on the New Madrid fault in the US Midwest would be triggered in December 1990 by tidal forces. In light of his prediction, serious social disturbances occurred. When the quake did not occur, he was ridiculed. Sol & Turan (2004) note that one can not use the defense of free speech to support predictions such as this since they create social disturbances with harmful consequences. Your speech has consequences.

Mr. Browning rejected scientific protocol and valid criticism but used the press to create a stir. While these actions were unethical if one subscribes to the ideals of the scientific community, the media also shares some blame for giving Browning’s opinion credibility it did not deserve. Several cranks persist in using this same “tidal forces” idea, unsupported by science, to gain attention from the media.

Katrina

Hurricane Katrina in 2005 was the costliest and one of the deadliest hurricanes ever to hit the United States. A US House Committee (2006) investigated the catastrophe and found, though the forecasts were remarkably good, the right information did not get to the right people on time and decision-makers seriously underestimated the threat.

It was well known how vulnerable New Orleans was to hurricanes yet there were inadequate provisions, few acts of leadership, government ineptitude, misguided advice, and media hype of violence that together resulted in a pathetic governmental response and heightened death toll. Katrina also revealed ugly issues of race and class treatment which showed that being poor and black put one at a distinct disadvantage in a disaster situation. Previous federal government cuts for disaster preparedness had increased the vulnerabilities and taught a hard lesson about paying now or paying later.

Boxing Day Tsunami

The Sumatra-Indian Ocean tsunami of 2004 was an example of lack of coordinated monitoring, notification and evacuation procedures that caused an enormous and mostly preventable loss of life (Revkin, 2004). Fifteen minutes after the offshore quake that generated the deadly tsunami, U.S. scientists at the Pacific Tsunami Warning Center in Hawaii sent out a warning bulletin. In spite of attempts they made to contact counterparts in other countries, the calls were not answered; the information and warning did not get through. Thousands died along populated coastlines completely unaware of the incoming surge scientists knew was coming.

Back in 2003, Dr. Phil Cummings of Australia had pushed for an expansion of the tsunami network into the Indian Ocean. Formation of a study group was met with resistance from participating countries and the network was never expanded. In hindsight, it was noted that Dr. Cummings had accurately predicted the damage that would be done to Sumatra and India. This event put the new word “tsunami” into the vocabulary of many citizens around the world.

L’Aquila, Italy

Giampaolo Giuliani forecasted the 2009 L’Aquila earthquake in Italy based on radon ground emission readings – a scientifically questionable (but not outlandish) theory. Giuliani was reported to authorities for “spreading panic” by broadcasting his warnings weeks before the predicted event. Italian scientists assured the townspeople that quakes were not predicable and officials forced Guiliani to remove warnings from the internet (Neild, 2009; Mackey, 2009). When the predicted quake did not occur on the expected date, March 29, the Italian Civil Protection Agency denounced Guiliani as “an imbecile” (Israely, 2009). A quake occurred on April 6 destroying the central city of L’Aquila and killing more than 300 people.

In this case, a desperate scientist had made an attempt to do what he thought was the right thing. The government agency chose to use ridicule and censorship instead of providing a measured, coordinated response to a questionable scientific prediction. What might have been the result if a different tactic was undertaken?

In 2012, an Italian court convicted six of the scientists and a government official of manslaughter for failing to give adequate warning of the deadly earthquake. Were they at fault or just mistaken? What happens when scientists are held THIS accountable for a correct guess in an uncertain situation? The public will suffer.

The parties involved

Most crises are not instantly obvious. They take time to develop, sometimes from vague or contradictory signals (Boin & t’Hart, 2006 p. 49). Citizens expect public official to make critical decisions, provide direction and issue emergency warnings (Barberi et al., 2008). Because they are not experts on scientific topics, officials are vulnerable to misunderstanding and mischaracterization (Olsen, 1989, p. 38 and 139). Social scientists note “the public wants to hear things from people they trust” and “they want to hear things repeated”. Miscommunication can occur all too easily when an official speaks outside his area expertise and/or garbles the message. Constant, and correct communication is the key.

Predictions have a way of leaking to the press. The media can be an effective and critical means to deliver warnings and will look to experts for information and confirmation. Scientists, however, have not traditionally been open to making themselves available to address the public. One can argue that it is their ethical obligation to be accessible in such a situation and they MUST do so to establish and retain their place as a credible source of information. Otherwise, alternate, not-so-credible sources step in to fill the void.

New electronic media means word-of-mouth takes on a whole different scale as warnings from credible and non-credible sources are passed instantaneous around the world. “Prediction” via email or social network platforms is popular. Likely unaware that a warning is scientifically baseless, and without an easy way to judge its credibility, a receiver feels that she is doing a good deed by passing on a warning of impending doom. Warnings like this can cause undue concerns and economic effects.

The elemental question in predictive scenarios is: when is the evidence adequate to make a prediction to the public? Many prognosticators feel they have potentially life-saving information and are overcome with a moral obligation to inform the public regardless of protocol. They can’t seem to adequately assess the potential fallout if they are wrong. The public, however, considers costs of all kinds and is not always compelled to follow scientific advice. The public may be misled by a manufactured scientific controversy (such as vaccine dangers or global warming).

Science gets accused of oppressing unorthodox ideas that may form the basis of innovative prediction theory. The punishment for a scientific maverick can mean the end of a career. Desperate scientists with unorthodox ideas, rejected by their peers, will put forth their ideas to the community who will listen – the media and public.

The modern public generally has veneration for science and scientists (Posner, 2004 p. 97; Barberi et al., 2008). Yet, science can not deliver absolutes or provide guarantees. The prediction scenario must take public perception into account or the prediction will cause harm whether the event occurs or not.

The world’s most vulnerable population is the poor. Keys et al. (2006) asserts that expensive warning systems are a hard political sell if it is just to save the poor populations.

Governments and citizens will hesitate to undertake precautions that are expensive and time consuming. The public, however, is influenced by seeing others in the community (or, these days, online) taking a warning seriously (Mileti & Fitzgerald, 1993, p. 87). Where the people are poor, uneducated or distrustful of government (Bolin, 2006 p. 129), there can be a reluctance to accept an “official” warning to evacuate. People who feel they are in control of their lives take action to survive. Those who feel their lives are controlled by an external force will passively await whatever fate will come. Fatalistic attitudes, especially as a result of religious beliefs, are still encountered today, most notably in poor populations (Quarantelli et al., 2006 p. 19, and Bruce, 2001 p. 19). Leaders must be forthright to convince citizens to take the most reasonable course of action. Compassion for personal human concerns must be displayed for a warning to be heeded. Government must be prepared to follow through with obligations to the population whether the event occurs or not.

Conclusion

Many predictions are valid attempts to do the right thing under uncertain circumstances. There are social and political reasons why a prediction is taken seriously or completely ignored. The media and public may give a baseless prediction credence where the scientific community does not.

When the public, media and politicians become involved, a prediction becomes socially complex. Warnings must be delivered in relation to social conditions (Rodrigues et al, 2006b p. 486).

Government and scientists have an obligation to learn from historical events and not repeat mistakes. Even false alarms do not diminish future response if the basis and reasons for the miss are understood and accepted by the public (Sorensen & Sorensen, 2006 p. 196-7). Therefore, authorities should be willing to prepare their citizens without hesitation if the prediction is supported by science.

Science has an established process to be followed for a theory to gain acceptance. Scientists should be discouraged from short circuiting this process and appealing directly to the public. However, the scientific community must evolve its process to include modern technology and the new media in consideration of basic human needs and various responses to life-threatening events.

Science and society: The giant earthquake that launched a new era in geologic knowledge

I am a geologist by training and my main interest was natural hazards. I was not able to apply my interest to earthquakes or volcanoes as I’d hoped but I did get to help the public deal with sinkhole hazards that also cause property destruction and occasional loss of life. This short film is worth watching. It was a turning point in science and society – the geologic aspect.

Great Alaska quake

There is little sense in praying to be safe from a disaster but EVERY good reason to study, plan and prepare. The average person does not necessarily have to understand seismology or even basic geology to get a benefit from science, but citizens should CERTAINLY appreciate that our advances in knowledge and, consequently, in safety and environmental regulations are based on a scientific process. You can say that about a lot of areas of life. There have been more than one instance to defund these hazard programs and even the USGS itself. How short-sighted and stupid.

This is my philosophy: Science literacy means science appreciation first and foremost. It’s really important.

Do you Tet Zoo? Comments contain gem on Bigfoot footprints.

Do you love animals? I mean love them in the way that I do, by examining the chicken carcass you are cleaning to observe the bones, cartilage, tendons and joints; by checking out road kill to see what it was or stopping to check out the dead bird in the yard; by pulling out your huge Wildlife Treasure animal card file just to learn binomial nomenclature? Yeah, it’s not just pretty pictures of puppies and kittens. This is science, man.

Do you know the difference between a pterosaur, a plesiosaur and a dinosaur? Do you know how to pronounce “azhdarchid” or even know what that is? (It’s only one of the most amazing types of animals that ever lived.) Even if you just want to know those things, you must not miss out on one of the must read science blogs on the web by an actual palaeozoologist! And, best of all, there is CRYPTOZOOLOGY too!

Tetrapod Zoology – the blog by Dr. Darren Naish has turned eight years old this month. Check out the year in review, it’s incredible.

When I say there is cryptozoology, there is sound, professional, scholarly, thoughtful, skeptical cryptozoology – in my book, the only worthwhile kind. Check out this statement from Darren that appeared in the comments explaining Bigfoot footprints, which is too good to just leave in the comments of the piece:

People who specialise on sasquatch research often argue that alleged sasquatch footprints record anatomical features that demonstrate the biological reality of sasquatch, or reveal physical parameters (size, mass, stride length) that exceed those of humans. See Krantz’s and Meldrum’s books, for example. Fact is, firstly, the footprints they have in mind represent a tiny number out of the 100s of alleged sasquatch prints that have been reported – the features concerned are most assuredly not present in all alleged sasquatch prints that people see. The majority of sasquatch tracks don’t look biologically plausible at all, at least not to someone who is used to looking at the tracks of real animals.

Secondly, it’s now been shown that all of the supposedly ‘biologically convincing’ attributes of sasquatch tracks can be explained in other ways: the ‘dermal ridges’ are identical to the ripples that appear on plaster and seem to be an artefact of the cast-making process (see Matt Crowley’s work); the supposed mid-tarsal break (= metatarsophalangeal joint) looks either like a push-up pressure ridge (you can make these yourself depending on how you move your foot and throw your weight as you walk), the result of slippage during track-making, or resemble the joint already present in a percentage of humans anyway; and the overhanging side walls of some tracks can easily be explained by sediment slumping – a familiar and expected property of the substrate in which sasquatch tracks are made.

Claims made about toe movement are often vague (ask yourself: how well has this been demonstrated? Have you even seen good illustrations of a trackway where the author demonstrates, to your satisfaction, that toe position really varies from track to track? I’ve heard people say that this toe movement is present, but I’ve never seen it really demonstrated). In any case, the argument that toe movement cannot be hoaxed rests on the assumption that fake tracks are made by inflexible wooden feet. There are reasons, however, for thinking that the tracks are sometimes (or often) made by flexible, silicone rubber tracks (cf 1991 Mill Creek case).

Finally, as goes claims about size, mass and stride length – again, it’s difficult to ever find any data backing up these claims. They’re usually just claims, made without the required data, and without appropriate controls and checks and so on. As anyone who’s walked on soil will tell you, sediment that is soft and pliable at one point in time can be dry and hard at another point, meaning that you might make very deep tracks at one time, and be unable to make deep tracks at another. Any claims about the mass of the trackmaker should therefore be viewed with scepticism. As for stride length, people see great length between tracks and assume that the trackmaker was walking. But, when people trot or jog, their stride length increases, enabling them to easily match the stride length we see in sasquatch trackways.

There aren’t any sasquatch tracks that have really stood the test of time. Grover Krantz stated with absolute confidence that certain tracks were indisputably genuine. In fact, they had been manufactured by a man called J. W. Parker.

Today’s Bigfootology needs beating over the head with a clue stick. This is how you do it.

Wait, there’s more…

Speculative paleozoology done by professionals (Book Review)

all yesterdaysLast night, I simply could not read any technical stuff before bed so I browsed my Kindle looking for some entertaining reading. The thing is, I don’t really do much fiction, almost everything I have is nonfiction. Then I came across “All Yesterdays: Unique and Speculative Views of Dinosaurs and Other Prehistoric Animals” by Darren Naish, C.M. Kosemen, John Conway, and Scott Hartman. This was it, the perfect hour’s entertainment before bed perusing fascinating artwork and professional commentary regarding speculative reconstruction of prehistoric (and modern) animals. It was a lovely blend of nonfiction with a good dollop of fiction and I very much enjoyed it.

This book shows what might possibly (very likely) is off (completely wrong) about artistic reconstructions of dinosaurs, plesiosaurs and pterosaurs. Fun stuff. You will learn that animals are reconstructed “shrink-wrapped” and naked. It’s sort of because that’s all the evidence we have and must guess at the soft tissue adornments and coloration. But what if we got a bit creative. That’s what this book does. Fun stuff. Sometimes silly, but thought provoking. What if these animals behaved in a completely different way than we expect? Well why not draw that?

The last section is enlightening as real animals are portrayed in a way that mimics how we would interpret prehistoric animals – shrink-wrapped, with no fat or characteristic soft parts (like pointy cartilage ears), no fur, and out of context.

Defending the faith of cryptozoology

My latest post, regarding the rational vs non-rational response to the new cryptozoology book by Loxton and Prothero, Abominable Science, went live on Huffington Post yesterday.

Cryptozoology Gets Respect While Bigfooters Behave Badly.

When critical thinkers approach the subject of Bigfoot (or cryptozoology in general) with a focus on the evidence, they are met with reproach. We are challenging much more than the claim; we challenge their belief. They will resort to what Biblical literalists will do to evolutionists – they demonize, call us names, misquote, pick at small mistakes, and take words and ideas out of context. They create an extreme position and shoot it down (called a “straw man” argument) because it’s a power play to make them feel superior. (Note that some aggressive “skeptics” will do that and it’s not fair play in that case either.) All the while, they skirt the MAJOR flaws in their own conclusions.

Bigfoot-themed and other cryptozoology blogs and forums are typically hostile to skeptics, even moderate ones like myself. They can’t understand why we even want to participate since we are going to “deny” everything. Gee, sorry for being interested in the topic and in getting a good answer for peoples’ experiences. Questioning is not denying, it’s thinking.

A while back I challenged cryptozoologists to read the book and make a fair assessment. Some seem to have read it. Three known men gave it ridiculous reviews. They only read the parts that interested them and presumed judgement on the whole book. That is intellectually dishonest and really shallow, not to mention extremely arrogant, behavior. This is why we can’t take self-proclaimed cryptozoological experts seriously. They treat their subject more like a religion, based on faith.

Talking to kids about evolution is hard: State it clearly

I’ve found it a bit difficult to explain the concept of evolution to a child below the age of 10. You run into a problem defining all those “things” involved – like DNA and reproduction and population and deep time. Those are tough for kids to grasp (especially “populations”, I’ve noticed). Check out this video with adorable graphics and rather easy to understand explanations. Continue reading Talking to kids about evolution is hard: State it clearly
