How did dolphins evolve?
Archaeological evidence reveals that whales and dolphins evolved through time from four legged animals that were initially semi-aquatic, then mostly-aquatic, and finally to fully-aquatic marine mammals. The original forerunner is named Pakicetus and lived about 50 million years ago.Click to see full answer. In this way, how did dolphins evolved over time?Dolphins, rather surprisingly, are…

In this way, how did dolphins evolved over time?Dolphins, rather surprisingly, are mammals that evolved from animals that used to live on the land; in other words they went back to live in the sea. Scientists believe that dolphins evolved from a hoofed, land-living mammal called ‘Mesonyx’, and returned to live in the seas some fifty million years ago.Beside above, where did dolphins come from? The first oceanic dolphins such as kentriodonts, evolved in the late Oligocene and diversified greatly during the mid-Miocene. The first fossil cetaceans near shallow seas (where porpoises inhabit) were found around the North Pacific; species like Semirostrum were found along California (in what were then estuaries). Moreover, what did dolphins and whales evolve from? Both hippos and whales evolved from four-legged, even-toed, hoofed (ungulate) ancestors that lived on land about 50 million years ago.When did dolphins first appear on Earth? 5 million years ago
