Bay Area Skeptics SkepTalk: Sex, Male Bias, & Degeneration

Sex, Male Bias, & Degeneration by Dr. Melissa A. Wilson Sayres

The human X and Y chromosomes evolved from a non-sex ancestor. The X is still regular-sized, but the Y is degraded and puny. Dr. Wilson Sayres will talk about how this process occurs, and how we can use the sex chromosomes to understand why more nucleotide mutations originate from the sperm than from eggs.


WHO: Dr. Melissa A. Wilson Sayres researches human population genetics at UC Berkeley's Miller Institute. She started out as a mathematician in Nebraska, learned to program, and studied sex chromosome evolution at Penn State. Dr. Wilson Sayers is passionate about studying and communicating evolution research at all levels. Visit her blog.

WHERE: La Peña Cultural Center, 3105 Shattuck Avenue, Berkeley. A 6 minute stroll from the Ashby BART station.

    I loved this talk. The speaker was lucid and presented her material in an ordered way that a lay person, as I am, could follow. She also gave answers to scientists in the audience with clarity & was not afraid to say when she did not know. One of the best talks ever.

    Either this or the other, not both, depends on BART as well!
