Males and females in many species are often quite different from one another. The sex of an individual can have profound effects on how an organisms behaves, how it looks, how it lives and, in some cases, even how it dies. These differences are the product of different evolutionary forces acting on males and females, sometimes creating substantial conflicts between the sexes. In this talk, Judith Mank gives a quick tour of how sex is genetically programmed and how sex differences evolve.

Judith Mank is Professor in the Department of Genetics, Evolution and Environment at University College London. She is interested in understanding how form, behaviour and reproductive patterns have evolved through selective pressures.

  1. Interesting stuff, but the speaker, Judith Mank, gets X & Y confused more than once. Obviously, these are just slips of the tongue, but these errors will confuse many non-biologists who watch it.

  2. I laughed when she called males less useful, to be fair shes right. In a situation where say a large part of the population was killed a man could reproduce with many women where women have to spend a whole 9 months making a baby. Always kinda confused me as to why we produce around the same amount of males and females.

  3. Disagree with one of her comments: "If you're large and a male it doesn't help you at all…" Actually, being large and being a male helps you compete against other males for breeding rights.

  4. The truth about the human race, is that the aliens created Adam and Eve. Yes evolution is creationism. However you have to have DNA in order create a physical body . Our physical body is from Adam and Eve. The aliens are diverse just like us. Just remember that there are two different kinds of them. The devils are physical beings from another world as well. The movie prededor, is based on a true story. If you have a half a brain you would understand that.
