Answer:
The phenomenon is called convergent evolution
Explanation:
Convergent evolution is the name given to the evolutionary phenomenon whereby a similar characteristic appears independently in two unrelated species, that is, that do not have a direct common ancestor from whom they could inherit that characteristic. Similar characteristics resulting from evolutionary convergence are called analogues or homoplasms (from the Greek, “shaped in the same way”). This process is very common and can be explained by natural selection, since similar selective pressures tend to favor similar adaptations.
