An example of divergent evolution in finches The main difference between convergent evolution and divergent evolution is that convergent evolution is the development of similar features in two species with different ancestral origins whereas divergent evolution is a process where two different species share a common ancestor. Convergent evolution is the independent evolution of similar features in species of different periods or epochs in time.

In evolutionary biology, convergent evolution is the process whereby organisms not closely related (not monophyletic), independently evolve similar traits as a result of having to adapt to similar Structural basis for divergent and convergent evolution of catalytic machineries in plant aromatic amino acid decarboxylase proteins View ORCID Profile Michael P.

These new species appear different on the outside but are very similar internally. This pattern is also known as adaptive radiation, these species evolve… Divergent evolution is the process whereby groups from the same common ancestor evolve and accumulate differences, resulting in the formation of new species. Divergent evolution may occur as a response to changes in abiotic factors, such as a change in environmental conditions, or when a new niche becomes available. Main Difference – Parallel vs Convergent Evolution. Groups of organisms or species undergo natural selection over time due to environmental pressure, giving rise to different patterns of evolution. Parallel evolution, divergent evolution, and convergent evolution are the three main patterns of evolution.
