Harvard study models forelimbs of echidnas to shed light on evolution

Using a detailed, musculoskeletal model of an echidna forelimb, Harvard scientists are not only shedding light on how the little-studied echidna’s forelimbs work, but also opening a window into understanding how extinct mammals might have used those limbs.

Study examines how mammal backbones changed during evolution

Harvard scientists are using the fossil record and a close examination of the vertebrae of thousands of modern animals to understand how and when specialized regions in the spines of mammals developed.
