Question

The Canary Islands are the cluster of seven islands that lie just west of Africa after their first formation the islands gradually become colonized with life plants lizard Birds Etc three different species of lizards found on the islands are similar to one species that found on the African continent because of this scientist assume that the lizard travelled from Africa to Canary Islands by floating on the tree trunks wash out of the sea what's good then cause one species to become three distinct species over time? explain

Answer 1

Answer: Allopatric speciation
Explanation:
The original ancestral lizard population was a single species with sexual compatibility among the individuals. These lizards have migrated to Canary islands and lost connection with the parent population and among themselves. They were subjected to different environmental conditions for several generations. As a result, they accumulated different mutations and ultimately evolved into three different species.

This is also an example of allopatric speciation by vicariance.
