WebThis is a deep question and something that evolutionary biologists spend a lot of time trying to understand! Homology is defined as the property of being descended from a common ancestor. This can apply to structures, DNA sequences, or even behaviors that can be traced back to an ancestor shared by two (or more) species. WebOverwhelming evidence supports these facts. Scientists continue to argue about details of evolution, but the question of whether or not different species are related through a long, shared history was answered in the affirmative at least two centuries ago.
