Jennifer Alice Clack, FRS (née Agnew; born 3 November 1947) is an English paleontologist, an expert in the field of evolutionary biology. She studies the "fish to tetrapod" transition— the origin, evolutionary development and radiation of early tetrapods and their relatives among the lobe-finned fishes. She is best known for her book Gaining Ground: the Origin and Early Evolution of Tetrapods, published in 2002 (second edition, 2012) and written with the layman in mind.
Clack is curator at the Museum of Zoology and Professor of Vertebrate Palaeontology at Cambridge University, where she has devoted her career to studying the early development of tetrapods, the "four-legged" animals said to have evolved from Devonian lobe-finned fishes and colonized the freshwater swamps of the Carboniferous period.
Early life and education
Clack was born on 3 November 1947 to Ernest and Alice Agnew. She was brought up in Manchester, England. She was educated at Bolton School (Girls' Division), an independent school in Bolton, Manchester. She received a B.Sc. in Zoology from the University of Newcastle upon Tyne in 1970, and a Ph.D. from the University in 1984. She also holds a Graduate Certificate in Museum Studies from the University of Leicester and an M.A. from the University of Cambridge. On 9 December 2000, she was awarded a Doctor of Science (ScD) degree by the University of Cambridge.
In 1981, Clack joined the University Museum of Zoology, University of Cambridge, as an Assistant Curator. She was promoted to Senior Assistant Curator in 1995. Since 2005, she has been Curator in Vertebrate Palaeontology at the museum.
In 1997, Clack was elected a Fellow of Darwin College, Cambridge; since 1 October 2015, she has been an Emeritus Fellow. From 2000 to 2005, she was Reader in Vertebrate Palaeontology the University of Cambridge. On 1 October 2006, Clack was awarded a personal chair by Cambridge, taking the title Professor of Vertebrate Palaeontology.
In 1987, during an expedition to East Greenland, Clack and her team discovered the remains of the Devonian tetrapods Acanthostega and Ichthyostega. Acanthostega is a transitional, water-bound primitive tetrapod.
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 .
In 2009, Clack was elected a Fellow of the Royal Society. She has also been elected a Foreign Honorary Member of the American Academy of Arts and Sciences. In 2014 she was made an Honorary Foreign Member of the Royal Swedish Academy of Sciences.
On 15 June 2013, Clack was awarded an honorary Doctor of Science (DSc) degree by the University of Chicago. The university described her as "an internationally preeminent paleontologist whose research has profoundly changed the understanding of the origin of terrestrial vertebrate life." On 17 July 2014, she was awarded an honorary Doctor of Science degree by the University of Leicester.
