Speciation can be driven by evolution, which is a process that results in the accumulation of many small genetic changes called mutations in a population over a long period of time. ... Natural selection can result in organisms that are more likely to survive and reproduce and may eventually lead to speciation.

What are 3 things that can lead to 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.

Does gene flow lead to speciation?

If two populations become isolated from one another and there is no gene flow between the two populations, they may develop into two distinct species. ... Speciation occurs when there is little or no inter-breeding (gene flow) between the two groups. Therefore we can say speciation is the result of reproductive isolation.
