Education and career

Presgraves earned his B.S. and an M.S. at the University of Maryland at College Park and a second M.S. and a Ph.D. in ecology and evolutionary biology from the University of Rochester. After completing his Ph.D, he was an Alexander von Humboldt Postdoctoral Fellow at the University of Munich and an NIH-NRSA Postdoctoral Fellow at Cornell University.[2]

Work

Presgraves' work has contributed to the current understanding of sexual selection, meiotic drive, and the X-Chromosome's evolutionary importance. His work has led to the confirmation of a phenomenon called the "large X-effect," which describes the integral role of the X-Chromosome as a wedge in driving speciation.[3]

Awards and recognition

In 2003, Presgraves was awarded the Dobzhansky Prize by the Society for the Study of Evolution in recognition of his accomplishments as an outstanding young evolutionary biologist. He was the first Dobzhansky Prize winner to have been trained by a previous recipient of the prize: H. Allen Orr.[2]

gollark: Here's a "helpful" illustration.
gollark: Consider the scenario: there are two boxes before you. One of the boxes (let us call it "A") is transparent and contains £10000, which you can see. The other box ("B") is opaque. It contains £1000000 if and only if the entity running this weird scenario predicted (beforehand) that you'll take box B and not box A. Historically, it has been right the vast majority of the time about this. Your options are to take both boxes, or just to take B. What do?!
gollark: Anyway, while I exist, Newcomb's paradox is a fun if not particularly related problem in decision theory.
gollark: When have I *ever* said false things?
gollark: I don't believe in beds.
