Darwin noted that island communities are often missing plants and animals typically found on continents.

What theory did Darwin propose?

Darwin proposed the theory of natural selection. It is the evolutionary change that is significantly based on the differential reproductive success of individuals within a species. He observed this process of natural selection in the Galapagos islands.

Darwin observed that the plants and animals of the Galapagos Islands were the same as those on islands off the coast of Africa with similar environments. Natural selection can cause the spread of an advantageous adaptation throughout a population.

Therefore, Darwin noted that island communities are often missing plants and animals typically found on continents.
