Blog 5 Explain how different species form (speciation)



By conbining one organism with another. A new specie formed when a population is isolated.When a group of individuals is separated from the rest of their species for a long time, the individuals can evolve different traits. The longer the group is isolated from the rest of the species, the more likely it will evolve into a new species.

Volcanoes and mountain ranges form. New islands are created. Ocean waves can carry small groups many miles away and put them down in a new place.
