The organisms have traits from their environments.

Detailed explanation-1: -Convergent evolution is the independent evolution of similar trait(s) in unrelated species. This usually happens because the species are living in similar (or the same) environments, so they evolve similar adaptations to face the same selective pressures. Notice how all of these organisms have similar body forms.
Detailed explanation-2: -Convergent evolution refers to the evolution in different lineages of structures that are similar or ‘analogous’, but that cannot be attributed to the existence of a common ancestor; in other words, the fact that the structures are analogous does not reflect homology.
Detailed explanation-3: -Molecular similarities provide evidence for the shared ancestry of life. DNA sequence comparisons can show how different species are related. Biogeography, the study of the geographical distribution of organisms, provides information about how and when species may have evolved.
Detailed explanation-4: -Divergent evolution: Divergent evolution occurs when two organisms with a common ancestor end up as different species. For instance, bats and mice share a recent common ancestor, but divergent evolution has turned them into two entirely different species.
