It appears that the field of ugly animal studies is wide open! Assessing the publication database for the years 1994 through 2008, the researchers found 1,855 papers about chimpanzees, 1,241 on leopards and 562 about lions — but only 14 for that mammalian equivalent of the blobfish, the African manatee. via A Masterpiece of Nature?

Scientists from the Beijing Genomics Institute last month discovered another striking instance of human genetic change. Among Tibetans, they found, a set of genes evolved to cope with low oxygen levels as recently as 3,000 years ago. This, if confirmed, would be the most recent known instance of human evolution. via Adventures in Very Recent […]
