In his follow-up to Sapiens, Yuval Noah Harari envisions what a 'useless class' of humans might look like as AI advances and spreads - "I'm aware that these kinds of forecasts have been around for at least 200 years, from the beginning of the Industrial Revolution, and they never came true so far. It's basically the boy who cried wolf, but in the original story of the boy who cried wolf, in the end, the wolf actually comes, and I think that is true this time." [more inside]
Sapiens: A Brief History of Humankind by Yuval Noah Harari - "The book delivers on its madly ambitious subtitle by in fact managing to cover key moments in the developmental history of humankind from the emergence of Homo Sapiens to today's developments in genetic engineering." Also btw, check out Harari on the myths we need to survive, re: fact/value distinctions and their interrelationships.
This Face Changes the Human Story. But How? This is the story of one of the greatest fossil discoveries of the past half century, and of what it might mean for our understanding of human evolution.
Dougal Dixon is a scientist, author, and illustrator.

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!)
Robert Krulwich tells the tale of Dr. Alan Rabinowitz and his friend... "Dawi told Alan the terrible secret that explained why there were so few Taron (left in the world). And then Alan told Dawi a secret of his own..." (includes audio link)

Really Old Skull debases "Out of Africa" theory. . . "The find calls into question a widely held hypothesis that the evolution of big brains propelled the exodus of early humans out of Africa."
