Mutation Linked to Difference Between Human and Neanderthal Brains
Dan Robitzski | Sep 9, 2022 | 5 min read
A single amino acid substitution in a protein causes increased neuron production in the frontal lobes of humans compared to Neanderthals—a tiny difference that could have given our species a cognitive edge, researchers say.

Who Sleeps?
The Scientist and Jerome Siegel | Mar 1, 2016 | 10+ min read
Once believed to be unique to birds and mammals, sleep is found across the metazoan kingdom. Some animals, it seems, can’t live without it, though no one knows exactly why.

SMALL HINTS, LARGE CHANGES:Courtesy of Rick Effland; Design, Erica P. JohnsonAlthough the genetic differences are small, as illustrated in the above stretch of FOXP2, and the neural differences still largely unknown, there is a world of difference between the mind of a chimp and the mind of a human.From our common ancestor with chimpanzees, it took only six million years, give or take, to develop the ability to speak. And, as we now know, the vast majority of our genetic material has been inheri

The 5,000-year-old mummy Öetzi, found in a glacier in the European alps 17 years ago and believed to be an ancestor of modern Europeans, actually belonged to a different genetic family and may have no living descendants, researchers report today in Current Biology. The researchers sequenced linkurl:mitochondrial DNA;http://www.the-scientist.com/article/display/19318/(mtDNA) extracted from Öetzi's intestines, offering the oldest complete mtDNA sequence of modern humans.
