“For about 23% of our genome, we share no immediate genetic ancestry with our closest living relative, the chimpanzee.”
When most people hear “Neanderthal,” they think of a primitive caveman-like prehuman brute. What many don’t realize is that this popular view is very much a Darwinian interpretation, and it is betrayed by much evidence.
Researchers trying to create a primate phylogenetic tree are finding it isn’t as easy as they’d hoped.
A new paper in the journal Nature, authored by paleoanthropologists Bernard Wood and Terry Harrison and titled “The evolutionary context of the first hominins,” is critical of the claim that Ardipithecus ramidus (“Ardi”) was a bipedal ancestor of modern humans. In 2009, the journal Science devoted an entire issue to introducing Ardi and promoting it as a likely human ancestor. It seems that Nature is in something of a rivalry with Science now that it has published this authoritative paper. When constructing phylogenetic trees, evolutionary biologists generally seek to minimize homoplasy, or instances of convergent evolution. Wood and Harrison observe that the problem for Ardi is that if she is on the human line, then there must be high levels Read More ›
As discussed in previous posts, the $1,990,459 taxpayer funded Evolution Readiness Project recommends reading to fourth graders a book called Life on Earth: The Story of Evolution. The book gives a misleading picture of the development of biological thought when it comes to common ancestry. It says that when “scientists were creating systems to organize living things by placing them into groups,” the same “scientists thought, many different plants and animals had come from the same ancestors and had changed over time.” The problem is that this omits the glaring fact that the father of taxonomy himself, Carl Linnaeus, was not an evolutionist and in fact believed in the fixity of species. While no one–including Darwin critics–would endorse in the Read More ›
