In saliva, scientists have found hints that a "ghost" species of archaic human may have contributed genetic material to ancestors of people living in Sub-Saharan Africa today. The finding comes from a University at Buffalo-led research project that examined the evolutionary history of MUC7, a gene that codes for an important salivary protein of the same name.

The Next Stage of Evolution: How Will the Human Species Evolve?
The Next Stage of Evolution: How Will the Human Species Evolve? Here are four possible futures for the human race, based on some theories of continuing evolution. The possibilities include a stop to evolution, continuing mutation here on Earth, technology hijacking evolution, and space colonies introduce differentiation into humans.
Snooze patterns vary across cultures, opening eyes to evolution of sleep
SLEEP SUPPLEMENT A Hadza forager in East Africa takes time out to catch a few z’s during the day. Naps enable the Hadza to catch up with their sleep after dozing an average of about 6.5 hours at night, researchers say. Evolution has reduced the quantity and boosted the quality of human sleep relative to other primates, they hold. ~~ D. Samson
5 Signs Humans Are Still Evolving
When we think of human evolution, our minds wander back to the thousands of years it took natural selection to produce the modern-day man. But are we still changing as a species, even today? New research suggests that, despite modern technology and industrialization, humans continue to evolve. "It is a common misunderstanding that evolution took place a long time ago, and that to understand ourselves we must look back to the hunter-gatherer days of humans," says Dr. Virpi Lummaa fr...
Why we're closer than ever to a timeline for human evolution
Dating when our ancestors split from Neanderthals and other relatives has long been a puzzle, but DNA advances are making our evolutionary journey clearer An artist’s rendering of Sima de los Huesos hominins, estimated to have lived approximately 400,000 years ago.
Caesarean Births Could Be Having an Effect on Human Evolution
This life-saving procedure could be changing us. Caesarean section (or C-section) deliveries can save lives when babies are too large to be born naturally - or if there are other health complications - but they also appear to be affecting how humans are evolving, scientists report.
Buff upper arms let Lucy climb trees
Arm, leg bone X-ray data provide clues to famous hominid’s mobility. ARM STRONG Relatively long, robustly built upper arms let Lucy, the famous 3.2-million-year-old hominid, spend a lot of time in trees, scientists say. Scans of Lucy’s fossils also suggest she walked less efficiently than people today do. ~~ J. Kappelman/Univ. of Texas at Austin
