Discovered in Messel Pit, Germany, the fossil, described as Darwinius masillae, is 20 times older than most fossils that explain human evolution. Known as “Ida,” the fossil [...]
Fingerprints of natural selection identified in the human genome
In a worldwide survey of 50 populations, a team of geneticists has identified many fingerprints of natural selection in the human genome. These are sites on the genome where specific sequences of DNA show signs of having become more common in the population, presumably because they helped their owners adapt to new climates, diseases or [...]
