Whales Evolution Essay
The Whale’s Evolution Whales evolved from an ancestor that lived on land. That may be incredibly hard to believe, but we have a lot of information to lead to that conclusion. Land mammals and whales have a lot more in common than you may think. Land mammals have hair, a nasal opening by its snout, arms, legs,etc, and DNA leading back to millions of years. Whales also have similar qualities to those of the land mammals. Whales weren’t always the whales we know today because long ago, before their evolution another animal excited. Evolution is the descent of any living thing with modifications over time. There have been two very bold claims there were; all living things are related and that evolution is powered by a natural process.

Modern day whales have hair, nasal passages, and have very similar anatomy. You may have thought that whales evolved from a fish, but in reality the whales evolved from a land mammal. Dolphins also are very close related to humans. Both dolphin and human embryos have arm and leg buds. They also have very similar bone structure and breathing abilities to land animals. This evidence means that dolphin embryos are closer related to land mammal embryos instead of fish. This piece of evidence is saying that dolphins, just like whales, are closer related to land mammals too because of their way of breathing, embryo comparison, and the structure of the nasal passages. The DNA of whales is closer related to that of hippos than that of fish. That means both the whale and the hippo have a common ancestor that existed roughly 54 million years ago. This evidence shows that all animals are related because we all evolved from one group or a couple groups of animals that existed millions of years ago. In conclusion, whales are closer related to land mammals than fish because of all the different qualities they have in common. They have very similar bone structure, DNA, breathing habits, ways they give birth, and so many other similarities. The whales and land mammals evolved from an animal that lived millions of years ago which is why they have so many similarities up until this very
