Chimpanzees' stone tool choices may mirror ancient human ancestors' techniques
An international team of paleobiologists, anthropologists and behavioral scientists has found that the process used by modern chimps to select tools for cracking nuts may be similar to how ancient human ancestors chose their ...
Lake bacteria evolve like clockwork with the seasons, study reveals
Like Bill Murray in the movie "Groundhog Day," bacteria species in a Wisconsin lake are in a kind of endless loop that they can't seem to shake. Except in this case, it's more like Groundhog Year.
