Question

How did Dobzhansky and Mayr explain the origin of species

A. it happens through adaption by natural selection.
B. it happens through allopatric speciation
C. It happens through sympatric speciation
Give me the answer

Answer 1

The answer is A. it happens through adaption by natural selection. Both Theodosius Dobzhansky and Ernst Mayr were proponents of the idea that species originate through the process of adaption by natural selection. They believed that genetic variations within populations could lead to advantageous traits that increase an individual's fitness, allowing them to survive and reproduce more successfully. Over time, these advantageous traits would become more common in the population, leading to the emergence of new species.
