Dogs and whales have descended from the same common ancestor. "The dolphins (and whales) belong to the cetacea (a phylogenic classification) and dogs belong to the carnivora. Both of these have evolved from a group called the mesonychidae." Reposted from a post by derrick kolling, Grad student, biophysics, university of Illinois urbana champaign.
To clarify, they are two different sets of species that are the great-grandchildren of a creature that had BOTH dog and whale characteristics. They just took different evolutionary paths to become the modern creatures we see today. So yes, they are distant cousins, but one did not descend from the other.
I was told at the Virginia Marine Science Museum that Egyptian dogs used to catch fish at the shores of the Ocean until one day they left the shore and became the largest mammal on the planet, the whale.

No there is no cold hard proof of macro evolution on large scale such as mammals evolving into large sea creatures.there is only one canine family that has never been anything else.
chrimps?
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
hard core
convergent evolution
Even in punctuated equilibria there are no distinct "steps" in evolution. But a single significant event can be pointed out common to the evolution of both lineages: the initial divergence of the ancestors of whales and humans from a common ancestor, thought to have taken place between 70 and 60 million years ago.
Theory of evolution
Whales Are Mammals, Fish Are Not
There is no actual evolutionary link between whales and fish. Whales are mammals and looking at the structure of a whales flipper it looks a lot like a hand. Fish however have no bone structure in their fins.Second Answer:They're an example of convergent evolution - two structures with common features which have evolved like that due to a similar/the same purpose despite having unrelated origins. Flippers have hidden fingers.
no sharks are sharks and whales are whales. their is a differs between them.
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.
Whales are big and bacteria are small
whales and dolphins both have fins, but dolphins are much smaller than whales
