Its occurs when two species share a common ancestor and evolve a similar trait independent of each other .
Example -
Possums/Australian marsupial mammals are Parallel Evolution . They evolved the marsupial traits independently , but nonetheless share a common ancestor .
Convergent evolution
It occurs when two species without any close common ancestor and evolve a similar trait independent of each other .
Examples -
For instance, birds and bats have very different ancestors indeed. Bats are mammals and bird are not, but both have evolve wings with the capacity for flight .
The answer is D. The Palaeozoic era was characterized by the supercontinent of Pannotia which was located at the current position where Chile is, 500 million years ago. There is evidence that shows that central Africa was once at the polar regions due to evidence of glaciers in its geological rocks. Due to tectonic movement, the Appalachians and the Ural Mountains were formed in the resulting Pangea supercontinent.
