So, remember a few weeks ago when new genetics research challenged the accepted idea that humans and neanderthals had never knocked boots? Back then, I mentioned that we were waiting to hear from Svante Pääbo, a hominid genetics expert who was due to publish his findings from sequencing the neanderthal genome. The Pääbo data would be the key to clearing up this ancient soap-operatic mystery.
This week, Pääbo weighed in and the answer looks pretty clear: If your ancestors are from anyplace other than Africa, you've got a little neanderthal in you. And so did your great-great-etc. grandma.
In fact, researchers can actually narrow down the location where at least some of this hanky panky happened.
all non-Africans - be they from France, China or Papua New Guinea - share the same amount of Neanderthal DNA, suggesting that interbreeding occurred before those populations split. The timing makes the Middle East the likeliest place where humans leaving Africa and resident Neanderthals did the deed.
Interestingly, there's not any one trait or even genetic sequence that seems to come from the neanderthals. Everybody (except Africans) is a little bit neanderthal, but it's not the same little bit.

Can you “hear” motion or light flashes? If so, according to new research from City University London, you may be experiencing a not-so-rare form of synaesthesia. Synesthesia is the fascinating neurological phenomenon whereby stimulation of one sense involuntarily triggers another sensory pathway. For example, a synesthete might taste sounds or hear colors. (In this study, […]
Scientists declared the ruby seadragon a new species in 2015, but that was based on dead specimens in a museum. Now though, Scripps Institution of Oceanography biologist Greg Rouse who led the team that originally discovered the species, managed to find two of the wonderful fish swimming around the Recherche Archipelago, off the south coast […]
Scientific American summarized five of Donald Trump’s “major moves many see as hostile toward science.” They are: • Trump’s pick for head of the U.S. Environmental Protection Agency has actively battled its mission “To lead the EPA, Trump appointed Scott Pruitt, the Oklahoma attorney general who has long opposed environmental regulations and has questioned the science […]
