Which of the following is not true of the punctuated equilibrium theory?
1.
a. it was inspired in part by patterns observed in the fossil record.
b. it suggests that subgroups diverge and evolve at about equal and constant rates.
c. it suggests that most species undergo little phenotypic change during most of their evolutionary duration.
d. it proposes that most evolutionary change is concentrated in relatively brief episodes of change.
e. it appears to be well supported by the fossil record.

The following is not true of the punctuated equilibrium theory is ‘It suggests that subgroups diverge and evolve at about equal and constant rates.’ The answer is letter B. the statements ‘It was inspired in part by patterns observed in the fossil record’, ‘It suggests that most species undergo little phenotypic change during most of their evolutionary duration’, ‘It proposes that most evolutionary change is concentrated in relatively brief episodes of change’ and ‘It appears to be well supported by the fossil record’ best supports the punctuated equilibrium theory.

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.
