- Atavism
- Divergent evolution
- Homologous organs
- Analogous organs
- Atavism
- Divergent evolution
The correct answer is: Analogous organs
Pectoral fins of sharks and flippers of dolphins are analogous organs. Pectoral fins of sharks are not pentadactyle. The flippers of dolphins are pentadactyle.
Thus basic structure of pectoral fins of sharks and flippers of dolphins are different but both are useful in swimming and perform the same function

I. Microbial experiment shows that when the pre-existing advantagoeus mutations are selected they will result in the observation of new phenotypes. Over few generations, this would results in speciation
