Concerted evolution information


Concerted evolution is the phenomenon where paralogous genes within one species are more closely related to one another than to members of the same gene family in closely related species. In other terms, when specific members of a family are investigated, a greater amount of similarity is found within a species rather than between species.[1] This is suggesting that members within this family do not in fact evolve independently of one another. [2]

The concept of concerted evolution is a molecular process which leads to the homogenization of DNA sequences. [1]

As shown from the diagram on the right, as each organism evolves, it creates a species that is more closely related to their genes than anyone else in their species. This is demonstrated by the different colors of circles. If each different color is representing a different organism in one species, this is showing that once the blue and the orange reproduce, they create organisms that are incredibly alike to them (thus they are represented as the same color)

This fundamental process operates in all organisms, even if it doesn't seem ultimately present at every moment.
