Speciation occurs when two or more populations become so genetically distinct that they no longer interbreed with one another. There are multiple ways this can occur. The natural ways speciation can occur are allopatric, parapatric, and
What can cause speciation to occur?
Scientists think that geographic isolation is a common way for the process of speciation to begin: rivers change course, mountains rise, continents drift, organisms migrate, and what was once a continuous population is divided into two or more smaller populations.
What 3 things can cause speciation?
Mate choice, competition, and the variety of resources available are the key factors influencing how a species evolves into separate species, according to a new mathematical model that integrates all three factors to reveal the dynamics at play in a process called sympatric speciation.
