Population geneticist Spencer Wells leads us on
a tour around the globe, collecting blood samples
from thousands of men living in isolated tribes
from the Bushmen of Southern Africa to the
Chukchi of Northern Siberia.
The best parts are when he returns with the
results and the diverse ways in which people
and tribes react to the news of what science
says about their history. The Aborigines of
Australia and the Navajo of America politely
disagree with the geneticists’ conclusion that
humankind originated in Africa and began
spreading to other continents 2,000
generations ago.
Viewers need not agree with the findings of
Wells, either but this is certainly an interesting
journey into the remotest regions of human
habitation.
