Bonobo Mothers Meddle in Their Sons’ Sex Lives – Making Them Three Times More Likely to Father ChildrenJournal Article
New research shows that for bonobos, sex really is often a family affair. What’s more, rather than being an embarrassing hindrance, motherly presence greatly benefits bonobo sons during the deed.
"Nearly all mammals have the same number of cervical vertebrae, no matter how long or short their necks are--humans, giraffes, mice, whales, and platypuses all have exactly seven cervical vertebrae," said Jeff Spear, a doctoral student from New York University, and part of a team whose Leakey Foundation supported research explored why this characteristic has stayed the same through time and across species.
From the Field
Leakey Foundation grantee Kevin Hatala has recently returned from fieldwork near Nariokotome, in northwestern Kenya, where his research team did surveys and preliminary excavations of sites that preserve 1.5 million-year-old fossil footprints.
Small forest antelope in the Democratic Republic of the Congo have more to worry about than being eaten by leopards. In at least one portion of the forest, Weyn's duikers are the preferred meat consumed by bonobos, according to new research supported by The Leakey Foundation.
Ancient DNA research has revolutionized the study of human evolution, but some time periods and geographic regions have not yet yielded usable DNA. Leakey Foundation grantee Frido Welker is a postdoctoral researcher who is testing new methodologies for breaking down and extracting ancient proteins.
From the Field
Leakey Foundation grantee Chris Gilbert has returned from a successful field season in the Indian Lower Siwaliks. He and his team revisited known fossil localities, discovered new ones, collected detailed geological measurements, and found an additional specimen of the fossil ape Sivapithecus indicus.
A lot of our understanding of aging comes from studying human societies, which share food extensively and care for the elderly, things that wild apes don’t do. So what does it mean to be an aging ape in the wild, who has to fend and forage for themselves?
A new member of the human family has been found in a cave in the Philippines, researchers report today in the journal Nature. The new species, called Homo luzonensis is named after Luzon Island, where the more than 50,000-year-old fossils were found during excavations at Callao Cave.
