Using darwins observations, explain how zebras got their stripes

I believe it has something to deal with helping the zebras adapt to their surroundings.

Darwins observations explain that zebras have stripes to adapt to their surroundings.

They evolved over time and natural selection, in which heritable traits that help organisms survive and reproduce become more common in a population over time. So the parents may have evolved to have stripes by having the certain gene for it, and then it was passed down to all the others.

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.
