Trying to understand language evolution by looking at genetic variation.
“It makes you wonder if they became isolated from one another for cultural reasons, or if there was some sort of geographical isolation that led to the differentiation,” says Sarah Tishkoff, a human-origins geneticist at the University of Pennsylvania in Philadelphia.

Two studies exploring the genetics of hunter-gatherers and pastoralists in sub-Saharan Africa, where humans are thought to have originated, reveal that even though the click-language peoples of southern Africa live in close proximity, they belong to two distinct genetic clusters.
African neighbours divided by their genes
Geographically close human populations in southern Africa have been genetically isolated for thousands of years.

Super Science Circle – August 2012 Edition
It's time again for the latest edition of my Super Science Circle. If your stream is stale, import this shared circle and never want for knowledge again. And if anyone ever tells you Google+ is a ghost town, point them at this circle and demand they import it.
Please reshare this list, to help it spread wide and far. Do it! For Science!
If you're interested in my criteria, the circle contains:
1. People active on Google+
2. People who often post about science.I highly recommend that you import these people into a test circle and then evaluate them over the next month. Move over the people who really delight you to a more permanent circle. Then replace the test circle next month, when I share it again.
If you know anyone who should be included in this list, please let me know.
Super album with amazing pictures to look at during the last half hour of #sciencesunday…

Since I've gained so many new followers over the last few weeks I thought I'd reshare some of my albums with them!
This is my Abstracts and Patterns (Nature) album. It's a work in progress!
And since it's #ScienceSunday I may as well tag +Rajini Rao and +Robby Bowles as well!
Enjoy
