Two plant species live in the same biome but on different continents. Although the two species are not at all closely related, they may appear quite similar as a result of.

1. Parlall evolution

2. convergent evolution

3. allopratic speciation

4. gene flow.

Convergent Evolution

Explanation:

This is a form of independent evolution where similar features are developed by two species, which are not closely, living in different periods but the same biome.

Due to developing analogous structures they may appear to be similar. Most of these structures were not present in the last common ancestor of both groups. An example is the nature of wings in birds, bats and insects which serves the same purpose which is flight.
