Question 2 (1 point) The "fish with legs" fossil is of great importance to the study of evolution of land-
dwelling animals because:

A) It suggests that fish moved onto dry land and then evolved legs and hands later.

B) It suggests that land-dwelling animals did not evolve from fish.

C) It suggests that fish first evolved legs that allowed them to move out of the
water.

D) It is the missing link between whale evolution and the evolution of terrestrial
mammals.

E) All of the above.

answer; i believe the correct answer to the above question is ( friction)

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.
