Convincing evidence that limbs evolved while tetrapods vertebrates with four appendages were still water-bound comes from a fossil Clack discovered in the mountains of Greenland, in She gave the million year old specimen, a fossil of the creature Acanthostega, the nickname "Boris. Her study of Boris revealed that it was a fishlike animal with limbs.

We are tetrapods. There, she studied the fossilized tracks an early tetrapod left in the mud of the shallows of an ancient shore. She could tell from the tracks and the surrounding rocks that it was one of the early vertebrates to leave its footprints on land.

Abstract The transition from aquatic to terrestrial habitats was a seminal event in vertebrate evolution because it precipitated a sudden radiation of species as new land animals diversified in response to novel physical and biological conditions.

Since , she has been Curator in Vertebrate Palaeontology at the museum. She retired in and is now Emeritus Professor of Vertebrate Palaeontology at the museum. In , during an expedition to East Greenland , Clack and her team discovered the remains of the Devonian tetrapods Acanthostega and Ichthyostega. In April she was featured in an episode [9] of the BBC television series Beautiful Minds , a set of documentaries about scientists who have made important discoveries.

She is currently leading a major consortium project investigating some exciting new fossils from Northumberland and the Borders Region of Scotland which date from the Tournaisian stage of the earliest Carboniferous period. Collaborating with experts from the Universities of Southampton and Leicester, the British Geological Survey and the National Museums of Scotland, the team is studying the plants, fish, tetrapods and invertebrates which survived the end Devonian extinction and existed within the until now fossil-poor period known as Romer's Gap , as well as the environment and depositional conditions in which they lived.

More information can be found on the Project website. National Academy of Sciences. In , Clack was elected a Fellow of the Royal Society. The university described her as "an internationally preeminent paleontologist whose research has profoundly changed the understanding of the origin of terrestrial vertebrate life. In , she won the Palaeontological Association 's most prestigious award, the Lapworth Medal.

Clack has published the following books: [15]. From Wikipedia, the free encyclopedia. Jennifer Alice".
