Antropoid primates– the
forerunners of modern apes, monkeys and humans – first appeared in Asia, but
what happened to them when climate change rendered much of the region too cold
to be hospitable? A study published this week in the journal Science may
have the answer.
“At the Eocene-Oligocene
boundary, because of the rearrangement of Earth's major tectonic plates, you
had a rapid drop in temperature and humidity,” K. Christopher Beard, senior
curator at the University
of Kansas Biodiversity Institute and co-author of the new study,
explained in a statement.
“Primates like it warm and wet, so they faced hard times around the world.”
In North America and Europe, the
creatures died out when this cooling began approximately 34 million years ago,
but managed to survive in Africa and Southern Asia. Now, the discovery of a
half-dozen new fossil primate species in southern China had revealed that the
transitional period nearly wiped out these creatures, forcing them to migrate
to Africa to survive and evolve.
Beard and his colleagues spent
more than a decade working at a site in the Yunnan Province of southern China,
where they managed to unearthed jaw and tooth fragments belonging to six new
species of primates that help explained what happened to our forerunners during
this period.
