From Religious Beliefs, Evolutionary Psychiatry, and Mental Health in America, Volume 1 of the series Religion, Spirituality and Health: A Social Scientific Approach pp 49-54 at Springer: Reactions to Darwin’s Origin of Species by Kevin J. Flannelly, Abstract: The chapter describes the initial reaction of the British general public to the 1859 publication of Charles Darwin’s Origin of Species, the immediate and later reactions of the scientific community, and the 20th Century response of Conservative Christians in the U.S. The British public had a generally favorable reaction to Origin of Species when it was first published, and it has been said that the British public widely accepted that the theory of evolution was true within a decade of the book’s publication.

From ScienceDaily: A study recently published in PLOS Biology provides information that substantially changes the prevailing idea about the brain formation process in vertebrates and sheds some light on how it might have evolved. The findings show that the interpretation maintained hitherto regarding the principal regions formed at the beginning of vertebrate brain development is not correct. … Amphioxus, considered close to vertebrates, was used in the research. This work shows that the brain of vertebrates must have formed initially from two regions (anterior and posterior), and not three (forebrain, midbrain and hindbrain), as proposed by the current prosomeric model. … The idea that these regions were formed independently and that each one of them has given rise to other Read More ›

Abstract for 2015 Wilkins-Bernal-Medawar Lecture: Who Cares about the History of Science? by Cambridge science philosopher Hasok Chang: The history of science has many functions. Historians should consider how their work contributes to various functions, going beyond a simple desire to understand the past correctly. There are both internal and external functions of the history of science in relation to science itself; I focus here on the internal, as they tend to be neglected these days. The internal functions can be divided into orthodox and complementary. The orthodox function is to assist with the understanding of the content and methods of science as it is now practised. The complementary function is to generate and improve scientific knowledge where current science itself Read More ›

Well, the file is open. From Colin Barras at New Scientist: An extraordinary chapter has just been added to the story of the First Americans. Finds at a site in California suggest that the New World might have first been reached at least 130,000 years ago – more than 100,000 years earlier than conventionally thought. If the evidence stacks up, the earliest people to reach the Americas may have been Neanderthals or Denisovans rather than modern humans. Researchers may have to come to terms with the fact that they have barely scratched the surface of the North American archaeological record. More. Barely scratched the surface? Now, that part we should have realized a long time ago. We didn’t find what Read More ›

From Kirk Durston at Contemplations: The first mistake is the failure to distinguish between classical forms of information vs. functional information, and is described in a short 2003 Nature article by Jack Szostak.(2) In the words of Szostak, classical information theory “does not consider the meaning of a message.” Furthermore, classical approaches, such as Kolmogorov complexity,(3) “fail to account for the redundancy inherent in the fact that many related sequences are structurally and functionally equivalent.” It matters a great deal to biological life whether an amino acid sequence is functional or not. Life also depends upon the fact that numerous sequences can code for the same function, in order to increase functional survivability in the face of the inevitable steady Read More ›

From ScienceDaily: Scientists have looked at all 14,500 participants in Children of the 90s and found that if a girl’s maternal grandmother smoked during pregnancy, the girl is 67 percent more likely to display certain traits linked to autism, such as poor social communication skills and repetitive behaviors. … The discovery, published today in Scientific Reports, is part of an ongoing, long-term study of the effects of maternal and paternal grandmother’s smoking in pregnancy on the development of their grandchildren, who are all part of Children of the 90s. By using detailed information collected over many years on multiple factors that may affect children’s health and development, the researchers were able to rule out other potential explanations for their results.

From Bob Holmes at New Scientist: How can we search for life on other planets when we don’t know what it might look like? One chemist thinks he has found an easy answer: just look for sophisticated molecular structures, no matter what they’re made of. The strategy could provide a simple way for upcoming space missions to broaden the hunt. Until now, the search for traces of life, or biosignatures, on other planets has tended to focus mostly on molecules like those used by earthly life. Thus, Mars missions look for organic molecules, and future missions to Europa may look for amino acids, unequal proportions of mirror-image molecules, and unusual ratios of carbon isotopes, all of which are signatures of Read More ›

In an interview with science writer John Horgan, who starts out by saying, At its best, physics is the most potent and precise of all scientific fields, and yet it surpasses even psychology in its capacity for bullshit. To keep physics honest, we need watchdogs like Peter Woit. He is renowned for asserting that string theory, which for decades has been the leading candidate for a unified theory of physics, is so flawed that it is “not even wrong.” That phrase (credited to Wolfgang Pauli) is the title of Woit’s widely discussed 2006 book (see my review here) and of his popular blog, which he launched in 2004. Woit, who has degrees in physics from Harvard and Princeton and has Read More ›

From Denyse O’Leary (O’Leary for News) at MercatorNet: In 2015, Eric Posner, a law professor at the University of Chicago, announced that “universities are right—and within their rights—to crack down on speech and behavior. Students today are more like children than adults and need protection.” Why today in particular? Is it possible that decades of proselytism for left fascism by their teachers have left their mark? The rioting students are not dissidents but conformists. So many people don’t want to face how marchin’, marchin’ affects the sciences: The sciences are especially hard hit. In a post-fact science world, objectivity comes to be seen as sexist if not racist, and engineering is suspect. Does it feel odd to you, reader, that young Read More ›

From board member Barbara Cargill via Evolution News & Views: On Friday, April 21, the State Board of Education voted on the final language for the streamlined TEKS (Texas Essential Knowledge and Skills). Some news reports have given erroneous information about the revised standards. The streamlined TEKS in biology continue to call for critical thinking in the study of theories such as evolution. They specifically call for students to “analyze and evaluate” the evidence for common ancestry and Darwinian natural selection. They further call for students to “compare and contrast scientific explanations for cellular complexity.” And they call on students to “examine scientific explanations of abrupt appearance and stasis in the fossil record” and “examine scientific explanations for the origin Read More ›

These people are really reaching. From Alison Klesman at Astronomy Magazine: In a study led by Ruari Mackenzi and Tom Shanks at Durham University’s Centre for Extragalactic Astronomy and published in the Monthly Notices of the Royal Astronomical Society, the group explores the possibility that a “supervoid” of space — an area lacking a significant number of galaxies and other matter — is responsible for the Cold Spot. Both regular matter and dark matter tend to clump together in space, forming structures such as clusters and walls in some areas, while leaving voids without much material in others. This effect is exacerbated by the expansion of the universe, and causes the CMB coming from the direction of a void to Read More ›

In the ongoing AJ vs ID discussion thread, major tangential debates have developed. One of these is on the IS-OUGHT gap, and it is worth headlining due to its pivotal worldviews importance (and yes, this is a philosophy issue). Let us start with Seversky, highlighting his key contention — which is commonly asserted: Sev, 261: >>Origenes @ 258 The matter seems very simple to me: because fermions and bosons are completely indifferent about morality, it is not possible to ground morality for atheists/materialists. You cannot logically derive “ought” from “is”. No one can, not even God. So, if our morality is God-given, how did He – or, indeed, any other being – derive it? Did He toss a coin?>> Origines, Read More ›
