New discovery of the physique of mammals

According to a study published November 25 in the United States, due to not being competitive by large reptiles, mammals eat a lot and use their new physique to warm up and fight off those Predator.

Research shows that when dinosaurs appear on Earth, the average physique of mammals is small, at least as small as a baby rabbit, and the largest is a rabbit hound.

When dinosaurs become extinct, the maximum physique of these animals is from 1 to 10kg. However, the growth of mammals did not take long after the extinction of dinosaurs 65 million years ago and 25 million years later, their physique has increased by 1,000 times with gravity. The maximum amount is 17 tons. Until then, they had to scramble for food with larger dinosaurs.

According to the same study, living in cold climates is not a problem for mammals' lives once their physique develops.

Mammals with large stature will not have to struggle to keep their bodies warm. Cold climates tend to favor their evolution.
