'U' professors unveil alleged 'missing link'

Ancient fossil offers
alternative view of
human origins
Managing News Editor
Two University professors were
part of an anthropological dream
team that recently unveiled a
47-million-year-old primate fossil
that sheds new light on the origins
of humans.
Philip Gingerich, director of the
University's Museum of Paleontol-
ogy and B. Holly Smith, associate
research scientist of the Univer-
sity's Museum of Anthropology,
contributed to the study of a new
primate species, Darwinius masil-
lae - dubbed Ida for short. Ida
represents an arboreal quadruped

that roamed the forests of Messel,
Germany nearly 50 million years
The fossil is gaining attention
because it's one of the most com-
plete primate fossils ever recovered
and represents an ancient primate
group that researchers now believe
monkeys and apes - and, subse-
quently, humans later on - evolved
"It was a real privilege to study,
because I do have to say, I've never
seen a fossil that has so much
information out of it," Smith said.
Smith added that the fossil was
so well preserved that its stomach
contents were still intact.
Ida, is believed to have been a
weaned, juvenile female who died
before one year of age. She is a
member of the adapoid primates, a
group that was formerly thought to
have contributed solely to modern-

day lemurs and set aside from the
lineage of monkeys and apes.
But, Gingerich, Smith and the
the fossil concluded based on cer-
tain morphological characteristics
more similar to monkeys and apes
than to lemurs that the adapoid
group cannot be dismissed as an
outlier in human evolution.
"This animal has front teeth
incisors like ours, like monkeys
and apes and humans do," Gin-
gerich said. "It doesn't have point-
ed incisors like tarisers and not
combed incisors like lemurs. It
also has toes, and if it's a lemur it
should have a grooming claw, but
it doesn't."
According to Gingerich, Ida was
found 20 to 25 years ago when an
amateur fossil hunter in Messel,
Germany, walked through a rock
pile and found a slab of rock and
split it in half. One half exhibited
an intact half of the fossil, while
