First step in speciation

WebSpeciation is of two types: Type # 1. Allopatric Speciation: Allopatric speciation is the evolution of species in a population that occupy different geographical areas. Geographic isolation is often the first step in allopatric speciation. Other isolating mechanism may also operate that further restrict reproduction between populations. WebOften this type of speciation occurs in three steps. First, the populations become physically separated, often by a long, slow geological process like an uplift of land, the movement of a...

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? Let's delve deeper into allopatric speciation. 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. At some point in this process, some of these genetic changes cause the two populations to become reproductively isolated from each other.
