Instuderingsfrågor The divergent evolution is defined as the process in which the groups having the same ancestor evolve and accumulate differences and the result comes as the formation of new species. The divergent evolution can from a response to change in Abiotic factors like a change in environmental conditions or when a new niche available. Artbildning är när nya arter uppstår, och orsaken till livets stora mångfald.

En klassisk jämförelse är mellan pungdjur i Australien och högre däggdjur Divergent evolution or divergent selection is the accumulation of differences between closely related populations within a species, leading to speciation. Divergent evolution is typically exhibited when two populations become separated by a geographic barrier (such as in allopatric or peripatric speciation ) and experience different selective pressures that drive adaptations to their new environment.

Groups of accessions are presented according to At5g10330 and/or At1g71920 genotypes and transcript accumulation phenotypes. Accessions (underlined) from each group were crossed to Col and/or Cvi and tested for LD1 incompatibility and compatibility to confirm the loss of function of one or the other duplicate gene. Q. Sharks and dolphins look very much alike-- both have streamlined bodies, fins, and sharp teeth. Sharks and dolphins, however, show every few similarities in protein and DNA structures implying that they are not closely related.

Egenskaperna utvecklas inte likartat på grund av att de har en gemensam förfader, det är enbart framkallat genom ett likartat levnadssätt.
