Webb14 maj 2024 · Evolution involves two interrelated phenomena: adaptation and speciation. In adaptation, over the course of time, species modify their phenotypes in ways that permit them to succeed in their environment. In speciation, over the course of time, the number of species multiplies; that is, a single species can give rise to two or more descendant ...
