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.

What bs!
Life has all the necessary components
Contained within the
Egg, female egg.
No Y means
No troubles!
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.
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.
I wanted to see video on evolution came across this video. She is amazing.
Intelligible speaking cadence interrupted by rapid mumbles of important info. Couldn't get through it.
At 6:52 X chromosome going to die? And just before is Y bigger than X. ???
Audio is far too quiet
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.
it's nice to hear somebody from a college saying there's only two genders
6:49 x chromosome or y chromosome?
6:40 small x large y chromosome? I don't get it, is she implying different thing or I am just dumb lol
This is hate speech. Differences between males and females oh my
Doing God's work. Thank you!
Red hair does it for me.
OMG she said too much diversity, at last somebody has had their fill of diversity
Safety is the biological
at 9.03 what is that behaviour? men will go and species will die. Her face looks like lost, confused and perplexed
satellite male is the neighbor and the sneaker male is the mail man
Because fish & humans are the same. Stop it
I know how we evolved. From the mud that God formed us from and eve was made by Adams rib.
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.
