They spent a lot of time ridiculing what they should have been studying. They ridiculed the now commonly accepted idea that a lichen was algae and fungi living as if they were one organism: The very notion of different organisms living so closely with—or within—each other was unheard of. That they should coexist to their mutual benefit was more ludicrous still. This was a mere decade after Charles Darwin had published his masterpiece, On the Origin of Species, and many biologists were gripped by the idea of nature as a gladiatorial arena, shaped by conflict. Against this zeitgeist, the concept of cohabiting, cooperative organisms found little purchase. Lichenologists spent decades rejecting and ridiculing Schwendener’s “dual hypothesis.” And he himself wrongly Read More ›

Four hundred and thirty million years ago, according to ScienceDaily: The discovery made by FAU palaeontologists Dr. Sebastian Teichert, Prof. Dr. Axel Munnecke and their Australian colleague Dr. William Woelkerling has far-reaching consequences. ‘Our finds mean that we must now look at the fossil record in a completely new way’, explains Dr. Sebastian Teichert. Up to now, a higher age for coralline red algae was thought to be so unlikely that fossils found in layers of rock older than the Cretaceous Period were not even considered as coralline red algae simply due to their age. The fossil record comprises all documented occurrences of fossils and is the essential source of information about how life on Earth developed. A re-evaluation of Read More ›

Teeth from the upper jaw of a child (the Xujiayao child) of about 6 and a half, who died between 100,000-200,000 years ago were examined by X-ray: But the ancient child’s overall dental growth and development falls within the range observed among kids today, paleoanthropologist Song Xing of the Chinese Academy of Sciences in Beijing and her colleagues report online January 16 in Science Advances. That humanlike rate of dental development suggests that the youngster belonged to an East Asian Homo population with a relatively long life span and an extended period of child care, the researchers speculate. Those characteristics are associated with present-day humans’ lengthy period of tooth growth.Bruce Bower, “An ancient child from East Asia grew teeth like Read More ›

A writer encountered this all-too-common type of behavior recently and was, well, surprised. To see why it feels normal to many of us, it is helpful to understand a bit about Darwinism as a social phenomenon. Faithful readers of various vintages will, of course, remember University of Toronto evolutionary biologist Larry Moran, best known publicly through his blog Sandwalk. At his blog Southern Prose, writer John Leonard happened to come across him the other day trashing well-known chemist James Tour. That was back in 2014 but the internet is forever. Tour signed the Discovery Institute statement, “A Scientific Dissent from Darwinism” (2001), calling for more openness on discussion of evolution: “We are skeptical of claims for the ability of random Read More ›

They’ve heard lots of noise but also seen lots of foot-dragging, about making research reports available publicly for free: The board told Nature that given the journal’s subject matter — the assessment and dissemination of science — it felt it needed to be at the forefront of open publishing practices, which it says includes making bibliographic references freely available for analysis and reuse, and being open access and owned by the community. “It’s essential that this work be made openly available and that the communication of the research be managed by the community,” says Cassidy Sugimoto, an information scientist at Indiana University Bloomington and a resigning board member. Board members also wanted Elsevier to lower the journal’s article-publishing charges for Read More ›

And the science paper that claimed so has been retracted. A team from the Shanghai Institute of Technology sought to study whether accuracy made any difference to whether a post goes viral on social media. They cited a concern about “the digital misinformation that threatens our democracy”: “The paper found that even though individuals may prefer to read and share “quality information”, factors such as “information overload and limited attention” contributed to “a degradation of the market’s discriminative power”. In other words, Qiu and colleagues concluded, quality material and the rate at which it spreads across the internet “reveals a weak correlation”. Low quality material – fake news, complete rubbish – is just as likely to go viral as the Read More ›

If they did, that’ll be even less reason to think of them as some kind of “missing link”: What if, long before Leonardo da Vinci or Michelangelo, the Neanderthals were humanity’s first artists? At any rate, this is the hypothesis raised by new dating of Spanish rock paintings published in February 2018 in the journal Science (link is external),indicating that the hands and animals depicted on the walls of three caves date back 65,000 years. This would mean that they were painted 25,000 years before the arrival of the first Homo sapiens in the Iberian peninsula. The estimated ages are based on uranium-thorium dating of the calcite layer that coats the frescoes. Could these be the work of Neanderthals? A Read More ›

Douglas Axe talks about a long-running dialogue he has had as a result of his 2016 book, Undeniable , where he can’t seem to get his dialogue partner to focus on what he is saying in his book and not what someone else is saying and what a fourth party is saying about them: But why address what Douglas Axe is saying when so many talking points against design in nature are tailored to what someone/anyone else is saying? We wish Axe all the luck. I think we’re addressing the same question, Hans. You’re absolutely right to focus on my treatment of the probability of organisms evolving by chance. Veering Off Course On the other hand, if you’re focusing on Read More ›
