Why do some animals run, but others cannot?

Because the species are different.

The campus is filled with countless hexagonal elves that look like flowers and butterflies, they silently moisten everything, and dress up the campus with a delicate magic wand, and the mischievous elves are unrestrained, cheerful, and light in the air performing a wonderful dance, perhaps because they have been in the sky for a long time, they seem to release the energy of the whole body, rendering all the ......

Listen, "Ding Ding dangdang", occasionally a few snowflakes fell on the fence, and then fell to the ground, like a high jumper, from time to time to make some crisp knocking sounds, it seemed that a lively ** meeting was held on the empty playground, however, the pure snowflakes finally turned into water, attached to the fence, the wind was blowing, they were crumbling, and they looked like they were unwilling to give up. In the melting snow, a whole new world is faintly reflected.

Until now, the snow is still falling, everything seems to be transparent, everything seems to have just been washed, and the rhythm makes people look forward to the next day when the snow will fall.

I love snow, I love winter even more, winter is the ring of the soul. Although it is very cold, it has an incomparable warmth and hope.

The difference in body structure is a difference caused by different evolutionary directions.

Animals with feet can run, but animals without feet can't.

Each species has its own laws.

2. Greyhound Retriever;

3. a hare; 4. Indian black antelope;

The leopard is the fastest, and the ostrich is also quite fast.

Speed Run: 1Animals that can run at high speeds are streamlined, so that the drag value can be reduced to a minimum when running.

2.Speed running consumes a lot of oxygen, so the nasal passages of animals that are good at running are usually larger than those of ordinary animals. (It's the nasal cavity, not the nose!)

You don't have to have a big nose to run fast! ） 3.The limbs are slender but powerful, especially the hind legs.

4.Very well balanced. 5.

Generally, the body of such animals is very thin, the bones are light, the muscles are tough, and the elasticity is good. Endurance Run: 1

The limbs are powerful, but not necessarily slender. 2.The body is strong and the muscles are strong.

3.The bite force is strong.

Leopard Profile: Rabbit Profile:

According to Darwin's "Theory of Evolution", animals are naturally eliminated due to various factors due to the environment and the natural selection method of survival of the fittest, and the remaining animals have inherited good genes. Because rabbits are at the bottom of the food chain, they gradually become short in the front legs and long in the long evolutionary process, and the muscles of the hind legs become developed, so they gradually adapt to fast running and are used to avoid natural enemies, so there is a certain scientific principle for rabbits to run fast.

Antelope Profile: The antelope can reach a maximum speed of 88 kilometers per hour, which is second only to the existence of the cheetah in the animal kingdom in terms of running ability. Antelope by the tendency of overbreeding, there is a struggle for survival in the antelope population, some antelope mutated the allele that runs fast, the ring (natural enemy) directional selection of antelope with fast running gene, the slow antelope is eliminated, the gene frequency of the antelope (running fast or slow) "running fast" gene frequency becomes high, the antelope evolves, so run fast!

Rabbits are the best animals at running!
