Rodents were diverse and abundant in prehistoric Africa when our human ancestors evolved
Date:12/21/2010

Rodents get a bad rap as vermin and pests because they seem to thrive everywhere. They have been one of the most common mammals in Africa for the past 50 million years.

From deserts to rainforests, rodents flourished in prehistoric Africa, making them a stable and plentiful source of food, says paleontologist Alisa Winkler, an expert on rodent and rabbit fossils. Now rodent fossils are proving their usefulness to scientists as they help shed light on human evolution.

Rodents can corroborate evidence from geology and plant and animal fossils about the ancient environments of our human ancestors and other prehistoric mammals, says Winkler, a research professor at Southern Methodist University and an assistant professor at the University of Texas Southwestern Medical Center, both in Dallas.

"Rodents are often known in abundance, and there are many different kinds from a number of famous hominid and hominoid localities," says Winkler. "Many paleoanthropologists are very interested in the faunal and ecological context in which our own species evolved."

Rodents: World's most abundant mammal and Africa's too

Rodents rats, mice, squirrels, porcupines, gerbils and others are the largest order of living mammals, constituting 42 percent of the total mammalian diversity worldwide. That's according to data drawn from the research literature in an analysis by Winkler and her colleagues, paleontologists Christiane Denys of the Museum National d'Histoire Naturelle in Paris and D. Margaret Avery of the Iziko South African Museum in Cape Town.

Their review documents more than 130 formally named genera in "Fossil Rodents of Africa," the first comprehensive summary and distribution analysis of Africa's fossil rodents since 1978. To see a flickr slideshow of rodent fossil images, go to http://blog.smu.edu/research/2010/12/rodents_were_
