The Evolution of Sex Determination
Nick Lane explores the fascinating mechanisms of sex determination across various species, highlighting temperature-dependent sex determination in amphibians and the unique sex chromosomes in birds compared to mammals. He discusses the role of the Y chromosome in growth factors and introduces the work of Ursula Mitf, who identified growth rate as a key factor in embryonic development, suggesting that this may explain why females often outlive males.
"And if you look at what determines sexes across the whole canvas of evolution, it's kind of weird because amphibians, for example, have temperature dependent sex determination. So males would develop ..."
