A Mismeasured Mismeaurement of Man. Stephen Jay Gould's classic The Mismeasure of Man argues that 19th century scientist Samuel George Morton inflicted his own racial biases on his data to demonstrate that Caucasians had larger brains than other races. A new paper in the Public Library of Science: Biology debunks Gould's account by remeasuring the same skulls Morton used. Whatever biases Morton may have had, they are not reflected in the data.
Husband-and-wife team Christopher Ryan and Calcilda Jethá have written a book, Sex at Dawn, that challenges what they describe as the "standard narrative" of human sexual and social relationships. In a recent Savage Love podcast featuring Ryan as a guest, Dan Savage described the book as "...the single most important book about human sexuality since Alfred Kinsey unleashed Sexual Behavior in the Human Male on the American public in 1948."

Indeed, at 6 million years of separation, the difference in [Y-chromosome] gene content in chimpanzee and human is more comparable to the difference in autosomal gene content in chicken and human, at 310 million years of separation.It is commonly said that the Human and Chimpanzee genomes share 99% or more identical DNA. In a surprising development about to be published in Nature, the Y-chromosomes of these two species were found to share only 70% of their DNA, raising important questions about the mode and tempo by which speciation from a common ancestor occurred. This finding may point the finger at the evolution of different patterns of sperm-competition and mating practices within these two species.

For most of us, science arrives in our lives packaged neatly as fact. But how did it get that way? Science is an active process of observation and investigation. Evidence: How Do We Know What We Know? [HTML version, Flash version also available] examines that process, revealing the ways in which ideas and information become knowledge and understanding. In this case study in human origins, the folks from the Max Planck Institute for Evolutionary Anthropology explore how scientific evidence is being used to shape our current understanding of ourselves: What makes us human—and how did we get this way?
How We Evolve: "A growing number of scientists argue that human culture itself has become the foremost agent of biological change, making us — for the past 10,000 years or so — the inadvertent architects of our own future selves." [more inside]
Lucy, one of the oldest and most complete fossilized hominid skeletons, is hitting the road. Although not without a little controversy. (And that's even before the creationists get wind of the tour!)
