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.

Convergent evolution: stick and leaf insects share 20 body features
A team of biologists in Montana and Germany has found that, regardless of type, those insects that express a protective stick- or leaf-like appearance all evolved the same basic body parts. In their study, published in the ...
Rare fossil embryos show early Ecdysozoa development in Cambrian era
An international research team has made a notable discovery of fossil embryos belonging to Ecdysozoa, a diverse group of animals including roundworms, velvet worms, insects, and crabs. These fossils, dated to approximately ...
