It is called convergent evolution. When two different animals have to adapt to the same environment (both whales and fish have to adapt to marine environments) evolution will make them start to look similar, even though they will still retain fundamental differences. For example, whales are mammals, and fish are... fish

Theory of evolution
Plate tectonics could have influenced the evolution of whales and dolphins by creating new habitats and changing ocean environments, which may have led to the adaptation of land mammals to aquatic life over time.
No dolphins had a different evolution from whales. Whales evolved from a footed creature similar to a hippo (no, seriously) and dolphins evolved from a footed creature a lot smaller.
The evidence for evolution in whales can be seen in their skeletal structure, particularly in the remnants of hind leg bones found within the body. These vestigial bones indicate a shared evolutionary history with land-dwelling mammals and suggest that whales evolved from terrestrial ancestors.
Is a Scientist who studies evolution, and prehistoric animals. A really cool discover was that whales used to be rather small land animal.
The similarity in DNA sequences between whales and ungulates is an example of genetic evidence for evolution, specifically molecular homology. This suggests that both groups share a common ancestor, supporting the theory of evolution by demonstrating how species can diverge from a common lineage over time. Such genetic similarities reflect the evolutionary relationships and the modifications that occur in different environments.
Because after millions of years of evolution, they now can't. Unlike their ancestors who were previously land animals.
vestigial organs such as a tail bone in humans and a hip bone in whales. also, the skeletal structure of wings of birds, flippers of whales, and hands of humans are all very very similar in structure.
Whales and Sharks are examples of coevoultion. they have very similar body shapes despite only being remotely related.
