Divergent evolution is the process through which individuals that share common characteristics develop and acquire differences, resulting in the emergence of new species.
WebAnatomy and Embryology. Another type of evidence for evolution is the presence of structures in organisms that share the same basic form. For example, the bones in human, dog, bird, and whale appendages all share the same overall construction (Figure 2) resulting from their origin in a common ancestor’s appendages. WebThe concatenation of these two processes–mutation and natural selection will result, as Darwin argued, in changes within populations (microevolution), and concomitantly, in changes between populations (macroevolution). Microevolution and macroevolution thus involve different mechanisms, and unfold over different time scales.
