Scientists trace evolutionary history of what mammals eat
Date:4/18/2012

The feeding habits of mammals haven't always been what they are today, particularly for omnivores.

Some groups of mammals almost exclusively eat meat--take lions and tigers and other big cats as examples.

Other mammals such as deer, cows and antelope are predominantly plant-eaters, living on a diet of leaves, shoots, fruits and bark.

But particularly for omnivores that live on plant foods in addition to meat, the situation wasn't always that way, finds a new study by researchers working at the National Evolutionary Synthesis Center in Durham, North Carolina.

The results appear today in the online edition of the journal Proceedings of the National Academy of Sciences.

"The research links dietary strategy, a basic aspect of animal ecology, with macroevolutionary diversification of mammals," said George Gilchrist, program director in the National Science Foundation's (NSF) Division of Environmental Biology, which funded the research.

"It's impressive that ecology has such a strong and clear influence on lineages stretching back millions of years. Darwin would be delighted with this paper."

Past research shows that animals with similar diets tend to share certain characteristics.

But this study is the first of its kind to look across all mammal groups, including omnivores, to reconstruct how evolutionary time changed mammal diets.

To do that, the researchers compiled previously published diet data for more than 1,500 species representing more than one third of mammals alive today, including primates, ungulates, bats, rabbits and rodents.

By mapping that data onto the mammal family tree, the researchers were able to trace backward in time and infer what the ancestors of each species most likely ate.

They found that while some groups of mammals maintained steady diets, others changed their feeding strategies over time.
