These new findings suggest modern humans likely didn't interbreed with H. However, the researchers stressed the differences between these ancient groups would have been "almost as low as seen between contemporary human populations," Gravel said. The way in which rainfall or temperature levels may have risen and fallen over time "would have reduced or increased geographic barriers to human migration." In addition, "there were also many changes in climate," study co-author Tim Weaver, a professor in the Department of Anthropology at the University of California, Davis, told Live Science. Distance, geographical obstacles and social barriers would likely have helped keep these groups physically separated for the most part, and they would have diverged genetically over time, he explained. The differences between these genetically distinct groups would likely have emerged because "Africa is a large continent," study co-senior author Simon Gravel, a population geneticist at McGill University in Montreal, told Live Science. sapiens suggests our species consisted of two or more genetically distinct human populations that had been interbreeding for hundreds of thousands of years. Still, before that split, the genetic variation seen in H. The earliest signs the researchers could identify of modern humans diverging into multiple groups in Africa happened about 120,000 to 135,000 years ago, with one population splitting off to become the ancestors of the Nama. The team found that modern humans in Africa may descend from two or more genetically distinct streams that divided but whose individuals continued to sporadically mate over time.

The study included newly sequenced genomes from 44 members of a southern African group known as the Nama. To shed light on this possibility, scientists analyzed modern human genomes from southern, eastern and western Africa. sapiens may have even interbred with ancient species significantly anatomically different from modern humans, such as Homo naledi, one of the most recently discovered extinct human species. See what I did and then have a ponder and think about the where the Wreck this Journal prompt will take YOU! And remember, you are supposed to WRECK the journal so if a page “goes wrong” or is “not to your liking”, it REALLY doesn’t matter.These recent discoveries raised the possibility that our species may have also interbred with " ghost lineages" within Africa - ancient relatives of modern humans not currently known of in the fossil record. However, sometimes, when your creative mind gets a little stuck, a prompt can be helpful, right? So take these ideas. Given a second go, I might complete it completely differently. These are just MY interepretations in a point in time. the whole point about the Wreck this Journal prompts, is that we all interpret a prompt differently to each other. the pages I have worked on to date! Now remember. So please do come back for more! So without further ado. ![]() ![]() I will add links to new pages that I have completed. I would like to make this a kind of “landing page” for Wreck this Journal Ideas. The ribbon/ leather strip bound journal DIYĪffiliate links added for convenience My Easy Wreck This Journal Ideas for Kids.OR why not have a go at making your OWN JOURNAL? I have two fabulous posts that shows you two different ways of How to Make a Journal: You can find the Wreck This Journal on Amazon here – US/ UK. so if you can get it onto your Birthday Wishlist or buy one second hand (which is what I did… I think it had one or two pages missing, but I don’t think it matters), that is great. I have to say it, IS nice to have the “real book”. ![]()
