55 million-year-old Archicebus is the oldest primate skeleton found,
the closest we've come to discovering our origins, and suggests we
evolved in Asia
Our distant ancestors evolved not in Africa but Asia, in a hothouse
world newly free of dinosaurs. Over 55 million years ago, in the lush
rainforests of what is now east Asia, a new voice was heard in the
animal chorus: the cry of the first primate. It is the earliest
primate skeleton ever found. It also strongly suggests that our
lineage evolved in Asia, several million years earlier than we
thought, and links the evolution of primates to the most extreme
episode of climate change of the last 65 million years.
Archicebus achilles as found in eastern China, just south of the
Yangtze river (Nature, DOI: 10.1038/nature12200). It is 55 million
years old, has the relatively small eyes of an animal active during
the day and the sharp molar teeth of an insect-eater. Significantly,
it also has the hindlimbs and flexible foot of a primate that had
already taken to leaping between branches and gripping onto them with
its feet – characteristics that we only lost when our ancestors left
the trees just a few million years ago. In fact, a recent study
revealed that at least 1 in 13 of us still has a flexible foot (New
Scientist, 1 June, p 11): the trait, it seems, may trace all the way
back to an animal very like Archicebus.
At the moment, analysis of Archicebus places it not on our direct
line, but with our next-door neighbours, the tarsiers of south-east
Asia. Archicebus is a basal anthropoid [the group comprising monkeys,
apes and humans - maybe. Parts of its body are eerily similar to what
we would expect to find in our oldest ancestor. Its ankle bone, in
particular, looks just like a monkey's – a feature that led to naming
the remarkable fossil after the Greek hero Achilles.
Perhaps most significantly, the new fossil supports the idea that
primates originally evolved in south-east Asia, and suggests the
ancestors of all monkeys and apes had already split off from other
primates 55 million years ago – millions of years earlier than
textbooks suggest. Archicebus solidifies that this important branching
event goes right back to the beginning of the Eocene. This links the
birth of our primate line to a major spike in global temperatures
known as the Palaeocene-Eocene Thermal Maximum (PETM). It also puts
our point of origin squarely in the heart of the PETM furnace:
equatorial Asia.
How, then, did Africa end up being the cradle of humanity? If the out-
of-Asia hypothesis is correct, early monkey-like primates must have
moved from Asia over to Africa, sometime around 40 million years ago,
Beard says. The hypothesis must still explain how they made the move,
crossing the vast Tethys Sea which separated Asia and Africa. this
and other recent finds suggest there was an into Africa' before 'out
of Africa'.
