Evolution Of Dolphin Research Paper
Dolphins are mammals, breath air, give birth and nurse their young ones. The ancestors of dolphins were animals that once lived on land but turned to the sea about 50 million years ago and never returned to land hence the dolphin’s ancestor had to slowly adapt to its new environment. Its front legs became flippers and its tail became flukes that it uses for swimming and steering respectively. The same bone structure is shared by bats, flying mammals in the order Chiroptera. While the trait for them was inherited from a common ancestor, the bones that form flippers in dolphins form a bat’s wings (homologous trait, example of divergent evolution) Its back legs diminished completely into the body. They have a layer of blubber beneath their

Gray Whales Evolution
166 Words | 1 PagesThe invertebrates that form the gray whales primary prey are restricted to shallow water environments, but global sea-level changes during the Pleistocene eliminated or reduced this critical habitat multiple times. Because the fossil record of gray whales is coincident with the onset of Northern Hemisphere glaciation, gray whales survived these massive changes by adapting their feeding habits. When continental glaciers locked up vast quantities of the earth 's water, ocean levels dropped up to 400 feet. This transformed what is now the sea bottom into wind-scoured steppes. At the height of the ice age, most of the modern gray whale food source would have been high and dry, and yet, the whales survived.
