Haplogroup G1, Y-chromosome mutation rate and migrations of Iranic speakers

The origin of Iranian speakers is a big puzzle as in ancient times there were two quite different groups of such speakers: nomadic steppe people such as Scythians and settled farmers such as Persians and Medes.I am guessing that theShow More Summary

Ice age Europeans on the brink of extinction

Ice-age Europeans roamed in small bands of fewer than 30, on brink of extinctionIn some cases, small bands of potentially as few as 20 to 30 people could have been moving over very large areas, over the whole of Europe as a single territory, according to Professor Ron Pinhasi, principal investigator on the EU-funded ADNABIOARC project.
