Researchers agree that our immediate ancestors, the upright walking apes,
arose in Africa. But the discovery of a new primate that lived about 37
million years ago in the ancient swamplands of Myanmar bolsters the idea
that the deep primate family tree that gave rise to humans is rooted in Asia
. If true, the discovery suggests that the ancestors of all monkeys, apes,
and humans—known as the anthropoids—arose in Asia and made the arduous
journey to the island continent of Africa almost 40 million years ago.

发帖数: 202 | 4 是啊,文章里提到非洲最早的化石与在亚洲发现的高度类似,但是亚洲的更为原始,
Asian Afrasia were more primitive than those of Afrotarsius from Libya,
particularly in the larger size of a tiny bulge at the back of its last
lower molar. These primitive traits, as well as the greater diversity and
age of early, or "stem," anthropoids in Asia rather than Africa suggest that
this group arose in Asia and migrated to Africa 37 million to 39 million
years ago. "Anthropoids didn't arrive in Africa until right before we find
their fossils in Libya," says Jaeger.
说明人类共同的祖先, And for humans, it would suggest that our deepest
primate roots were in Asia, not Africa
