Kissing is so commonplace that most people rarely think to stop and ask where humans picked up the habit in the first place. Where in humanity's evolutionary history did smooshing our faces together come to be regarded as a display of lust, care, friendship, and love?
How did smooshing our faces together come to signify love and affection?
An international team of researchers has mapped the genome of the bonobo for the first time, revealing that this great ape shares as much DNA with humans as its more aggressive cousin, the chimpanzee. Identifying and understanding how all three genomes overlap, researchers say, could offer new insights into what makes…
There are four genetically distinct chimpanzee populations, all found in two relatively small regions of Africa. And yet these populations, which are sometimes less than a mile apart, are more genetically diverse than humans that live on different continents.
Bonobos are famous as one of the relatively few species that has sex simply for pleasure. But just because our primate cousins aren't reproducing doesn't mean they're only having fun — as revealed by a new study of bonobo lesbian relationships.
Bonobos look like tame versions of chimpanzees. They're much less aggressive than chimps, their features are softer and smaller than their cousins, and they famously have sex for pleasure. Basically bonobos are domesticated... except humans had nothing to do with it.
Until recently, scientists figured that the origins of human language could be found in our vocal cords. That seems reasonable enough, but the latest evidence suggests our hands are actually the source of language...and a bunch of hand-waving primates agree.
