WebWhat is the first step in allopatric speciation group of answer choices? Two processes of speciation are thought to be important: allopatric speciation and sympatric speciation. Allopatric speciation: The first step in allopatric speciation is the restriction of dispersal between two or more populations that would otherwise freely interbreed.

WebSpeciation occurs when populations of a species, due to certain factors, evolve to become new, distinct species. Allopatric speciation, commonly referred to as geographic speciation, occurs when populations are split due to geographic isolation. How Does Allopatric Speciation Occur?

WebThe steps in speciation are- 1) Geographical or temporal separation of populations. 2) Evolution of hybrid sterility. 3) Evolution of isolating mechanisms. 4) Reproductive isolation.
