The ancient lizard whale is one of the most primitive whales and a huge whale, but what you can't imagine is that such a primitive giant whale actually ran down from the tree. According to archaeologists, about 50 million years ago, the earliest whales appeared in the ocean, and the only mammals, but the whales at that time were not the same as today, and it was not until the time of the ancient lizard whales that they really evolved into whales.
The ancient lizard whale, also known as the toothed whale, is a carnivorous whale, 18 meters long, 3 times the length of the great white shark, but it is difficult to imagine such a big guy, the ancestor would be a small, hairy mammal living in trees. According to recent fossil discoveries, the earliest whales appeared in the ocean about 50 million years ago, and the only mammals in the ocean.
According to estimates, the ancestors of whales are likely to have evolved from the middle beast, which is a mammal living by the stream, they are only 2.4 meters long, feeding on fish, but after a series of evolutions, evolved into walking whales, their four feet also have hooves for walking, but the feet are large, can play a webbing role, this time can not be considered a real whale, the real whale is from the ancient lizard whale.
3 million years after the walking whale, the Lord whale appeared, also only 2.4 meters, also belonging to amphibian mammals, but the size tended to be streamlined, but also evolved like a whale suitable for swimming large and elastic tail, until 10 million years later, the deep sea gradually became the home of ancient lizard whales, the real whale can be regarded as the emergence.
At this time of year, toothed whales flock to the northern shores of the ancient Mediterranean to mate. Several male toothed whales were pursuing a female, but in the end it chose the oldest and largest male to mate. Disasters from the far South Pole are changing the fate of this female ancient lizard whale, and for the first time in hundreds of millions of years, the oceans in the polar regions have frozen, and the currents have been disturbed. A whale needs 80 kilograms of food a day, and the slightest change in the ocean's fish population can have a big impact on the whale, and the food base on which the female whale depends for survival is about to collapse, but by this time she is pregnant.
Many people don't know that hippos are actually cetaceans, because they don't look like whales at all, and they look a bit like pigs, but according to genetic research, hippos are indeed related to whales. If you look at the hippopotamus alone, the ancient Greeks thought it was related to horses, and now scientists think that it has a relationship with pigs, but they did not expect to be an ancestor with whales.
According to early fossil studies, cetaceans and hippos have a common ancestor that lived in the water, about 50 million years ago, but this ancestor evolved two different species, one is the ancient lizard whale that lives in the deep sea, and the other is a variety of animals that look like pigs, which later multiplied rapidly, forming 37 different species, but 2.5 million years ago, most of these species were extinct, and only hippos survive to this day.
