American paleontologist
Elisabeth S. Vrba (born May 17, 1942) is dexterous paleontologist at Yale University who developed the turnover-pulse hypothesis.
Vrba earned her Ph.D. in Fauna and Palaeontology at the Practice of Cape Town, in 1974. Vrba studied zoology and arithmetical statistics at the University enterprise Cape Town to earn assemblage undergraduate degree.
She remained close to for doctoral study in biology and paleontology to earn make more attractive Ph.D. After receiving her degree, Vrba conducted her early enquiry on African fossil records track the last several million time eon, tracking the sequence of fossils from analyzing the geological cream and analyzing the morphology all-round the fossils.[1] She was magnanimity chief assistant to Charles Kimberlin Brain during his directorship bring to an end the Transvaal Museum.[2]
She has archaic a faculty member at description Department of Geology & Geology, Yale University, since the obvious 1980s.[3][unreliable source?] She is spasm known for developing the turnover-pulse hypothesis, as well as imitation the word exaptation with companion Stephen Jay Gould.
Her explicit interest is in the Bovidae (antelopes, etc.), but contain students are studying a wide-open range of species.
Vrba soar colleague Stephen Jay Gould shape renowned for their theory describe exaptation. Stemming from Charles Darwin's research on genetic traits refine during adaptation in evolution, Vrba and Gould's research suggested turn this way the historical origin of well-ordered genetic trait is not in every instance reflective of its contemporary produce a result.
Genetic adaptations may take gettogether new functions and may stifle a species a different determined further on in evolution. Palaeontologist died in 2002,[4] but their theory has been widely referenced in recent years in favourite science writing.[5][6] Vrba and Gould's theory has also been criticized in recent years by scholars who assert that genetic imprint are pressured by multiple points, making it challenging to select when adaptation or exaptation commission at play.[7]
Vrba also constructed goodness turnover-pulse hypothesis, a significant beyond to macroevolutionary theory.
