Scientists use pollen data to decode first humans' migration into Eurasia

New Delhi, Oct 1 (PTI) Pollen grains analysis helps understand how the first humans migrated from Africa across Europe and Asia, research in Science Advances says.

The pollen data showed that warming temperatures supported forests that expanded into Siberia and facilitated early human migration there, researchers from the University of Kansas, US, said in their study.

They compared Pleistocene vegetation communities around Lake Baikal in Siberia, Russia, to the oldest archeological traces of Homo sapiens in the region. Pleistocene period is considered two million to 11 thousand years ago and as the time of human evolution.
