Identify the examples of convergent evolution from the following: (i) Flippers of penguins and dolphins (ii) Eyes of octopus and mammals (iii) Vertebrate brains

Convergent evolution occurs when two groups of largely unrelated organisms are exposed to very similar environments and develop similar adaptations to survive. The examples of convergent evolution from the above-given examples are: (i) Flippers of penguins and dolphins (ii) Eyes of octopus and mammals
