Ecological Speciation

Speciation is an evolutionary process that leads to the formation of a new species.

Ecological speciation is the process of forming a new species due to ecological factors.

Natural selection plays a role in speciation by favoring individuals with traits that are beneficial for survival and reproduction.

<p>The two types of speciation are allopatric speciation and sympatric speciation.</p> Signup and view all the answers

<p>Allopatric speciation occurs when a population becomes reproductively isolated from the parent population due to a geographical event, such as the formation of a mountain range.</p> Signup and view all the answers

<p>Sympatric speciation occurs when there is no physical separation in the population, but selective pressures cause a divide between the organisms, preventing them from producing fertile offspring when they mate.</p> Signup and view all the answers
