In mammals, humans can only run on one leg, while animals run on both legs at full speed at the same time, accelerating faster and faster. In addition, the length of the limbs of the animals is consistent. When running, the lower back and abdominal muscles can stretch forward, while humans can only rely on their legs to push forward, and their upper body can only maintain balance, so animals can run very fast.
Even hippos can't run, it's quite normal, hippos live in the wild for a long time, they exercise a lot, and hippos are significantly larger than people and run naturally more in mammals.
<> hippos they can run at speeds of 30-40 km/h, with the fastest reaching speeds of up to 48 km/h. The world record for the 100-meter dash is seconds. During the day, hippos prefer to sleep in shallow water and occasionally on dense mudflats, where mating and childbirth occur.
When there is no shallow water, the hippopotamus will place its nostrils above the surface of the water and breathe in deep water. At dusk, hippos come out of the water and come ashore to feed.
Over short distances, hippos can easily beat the fastest man on the planet, reaching speeds of up to 30 kilometers per hour. However, due to their large size and the fact that they are prone to evaporation and loss of water, they have poor endurance on land and usually stay in the water.

Because human beings have not been able to run in the long evolution.
It can be said that all primates (humans, modern apes, monkeys, lemurs, etc.) are not very fast, this is because primates, from the time they appeared, were arboreal or semi-arboreal animals, sheltered by trees, and did not need to run quickly.
When the apes changed from arboreal to terrestrial and gradually evolved into humans, wisdom was already generated, and with the help of tools to improve their ability to defend themselves against natural predators and obtain prey, there was no need to run fast.
No living thing takes the time and effort to evolve and produce unwanted abilities. As a result, human eyesight is inferior to that of carnivores; Hearing and smell are inferior to herbivores; Running speed is also not good. But humans were able to compensate for almost all their physiological defects with their intelligence and tools, and became the most successful species in the history of biological evolution.
-
In mammals, people can't even run hippos, which is also very normal, hippos survive in the wild environment for a long time, regular exercise, and the hippopotamus is obviously much larger than the size of people, and the range of running is naturally greater.
-
This is a matter of human evolution, and now human beings do not hunt or hide from predators every day, and their ability to run will naturally deteriorate. It's normal to not be able to outrun other animals.
-
Because most of the animal kingdom is on all fours and runs on four legs, people only have two legs, and of course they can't run on four legs.
-
Because there are really only two legs, and animals have four legs, and of course two legs can't outrun four legs.
-
It's normal, people are two-legged animals, and they walk upright, and their explosive power is limited.
-
Why can't many animals outrun in mammitals, even live horses, oh, okay, fast, I don't know, I haven't been to see those animals.

The fastest mammal is the cheetah.
Cheetahs travel at speeds of about 115 kilometers per hour, and the genus Cheetah is the only species in the genus Cheetah, also known as the Indian leopard, which is the only species in the genus Cheetah, which mainly inhabits tropical and temperate grasslands, deserts and grasslands with open forests. Dust shed.
Cheetah is a carnivore, and its prey is mainly antelope, zebra, ostriche, etc., and can only prey one prey at a time, because although the cheetah runs fast, the distance and time it runs is not long. Cheetahs are mainly distributed in Algeria, South Africa, Zambia, Kenya and other African regions, and now due to the decline of herbivores, the lack of food for cheetahs, and the destruction of the living environment, the number of cheetahs has decreased, and it has been listed as an endangered animal.
Breeding of cheetahs
Cheetahs usually have a gestation period of about 3 months and usually have 2 to 8 pups per litter. Newborn cubs have dark brown coats with inconspicuous spots, and by the time they are 4 months old, their coats turn yellow-brown and their bodies are covered with black spots. The tail of the pups has black stripes and no spots, but when they become adults, they become the same color as their bodies, and the ends of their tails become white.
The pups have long, tall fur on their backs that run from the neck to the base of their tails, the so-called cape, which makes the cubs look like a honey badger, and this so-called cloak allows them to hide in the tall grass and help them escape from the threat of lions and coyotes. The light gray mantle on the back fades slowly and remains visible until 15 months of age when it reaches adult size.

The fastest speed of the cheetah can only be maintained for more than ten seconds, and it can't run for 3 minutes at all, and it is impossible to run 6 kilometers in 3 minutes.
Cheetah is a champion in sprinting, but not suitable for middle and long distance running.
Because when mammals use poison, their own condition will also be greatly damaged.
I personally think it is an ostrich, because the ostrich has a vision of 25 and can recognize objects within 10 km, and the ostrich can clearly see ants moving at a distance of 42 5 meters from it. Since the beginning of the Jurassic, birds have extensively adapted to the Cretaceous and evolved a variety of water and land birds to adapt to a variety of environments. After entering the new generation, due to the extinction of the terrestrial dinosaurs, the ecological status of mammals was mostly replaced by birds before they developed into large animals. >>>More

Blue whale.
The largest mammal in the world is the blue whale. It weighs about 170 tons and can reach a length of about 30 meters. Newborn calves weigh tons and are meters long. >>>More
In fact, many people are lethargic in winter, and animals even start their long hibernation directlyMainly because in winter, the animals feel very cold, and because they can't find a lot to eat, they choose to hibernate. <> >>>More
