Does Convergent Evolution Have a Common Ancestor?

Introduction. Convergent evolution refers to the evolution in different lineages of structures that are similar or 'analogous', but that cannot be attributed to the existence of a common ancestor; in other words, the fact that the structures are analogous does not reflect homology.

Which type of evolution shows a common ancestor?

Divergent evolution is the process in which a trait held by a common ancestor evolves into different variations over time. A common example of divergent evolution is the vertebrate limb. Whale flippers, frog forelimbs, and your own arms most likely evolved from the front flippers of an ancient jawless fish.

What is a convergent ancestor?

Convergent evolution is when different organisms independently evolve similar traits. ... From that ancient common ancestor, one lineage struck out on land and evolved into mammals, including the wolf-like Pakicetus, which would later return to the water and evolve into whales and dolphins.
