If Darwin was to be alive today, what do you think will be his observation on evolution?​

Darwin would be happy that his theory of evolution is correct. Stating that biological evolution is through natural selection of inherited traits that enable a species to survive, compete and reproduce.

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.

your answer would be a, maximum exploitation of resources.
