Some human traits may have arisen by sexual selection. over thousands of years, women attracted to charming, witty men perhaps prompted the development of human intellect beyond what was necessary for mere survival. men attracted to women with juvenile features may have shifted the species as a whole to be less hairy and softer featured than any of our simian relatives. can you think of a way to test these hypotheses?

Conduct an experiment to demonstrate the pattern of mate selection on the basis of unique traits.

Hope I helped answer your question:)

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
