Current Event

Genecists from Italy say that the first Americans crossed a land bridge connecting Asia and North America(more specifically Alaska) almost 17,000 to 15,000 years ago. Also, even more people with discernable genetic signatures may have walked across a land bridge called Beringia. Investigators say that this explains the mitochondrial DNA difference that Native Americans have. Native Americans still have this difference in there DNA. Skepticists say that a ice-free part of Alaska wasn't passable until 12,000 years which makes this quite harder for the New World migrants. Scientists say they still have much to learn about human migration. I think that this article is very interesting because it shows us the ideas of how the humans migrated to America. Also, this shows that the himans are very good travelers because they are supposedly from Africa.http://www.sciencenews.org/view/generic/id/39781/title/Migrants_settled_New_World_in_tandem
