Are animals that walk on two legs necessarily smarter than animals that walk on four legs? Why?

IQ is not desirable in terms of the number of legs, and there is no evidence that the fewer legs, the higher the IQ. Penguins and chickens also walk on two legs, but their behavior suggests that they are much less intelligent than large mammals, and the more objective indicator is the encephalogenesis index.

First of all, it should be noted that human beings have not yet invented a perfect way to measure IQ, and the current IQ measurement is nothing more than a comprehensive measurement of behavior, psychology and other characteristics, but humans and beasts do not understand each other, and naturally cannot well understand the psychology of animals, and there are deficiencies in the IQ measurement of animals. But if it is divided according to the brainification index, it is relatively objective, but it is only under the standard of our human race.

At present, the higher animals of life on the earth usually have differentiated nerve centers such as the brain and spinal cord, and the shorter the time for the species to appear (indicating the longer the years of biological evolution), the higher the degree of differentiation between the brain and the spinal cord, and the division of labor is more and more obvious. In contrast, humans have the highest encephalogenesis index (the proportion of brain mass in the whole body), reaching about 5, and the closest to humans are some species of dolphins, which only reach about 2, and there is a high difference in IQ from humans, and they don't even have legs, but they have fins and tail fins with alienated upper limbs.

Organisms walk on a few legs is only a difference in physiological structure, is the embodiment of the unique adaptability of organisms affected by the environment, and organisms adapt to the environment does not necessarily have a high IQ, like the key to penguin survival is to survive in the cold Antarctica, IQ does not matter, Antarctica lacks penguins natural enemies, and has a vast coastline, but because it is very cold, if you can't adapt to it will be extinct. Penguins are an ancient bird that has evolved a lot of fat and a special way of circulating blood in their feet in cold environments to minimize the loss of body heat.

But it may also be because of this that they are unable to evolve a higher IQ, and the body consumes more energy to keep warm, which limits the development of the brain. Human beings are a special case of nature, in the course of evolution, human body hair has gradually decreased, but human beings have gradually become more suitable for the environment, mainly human beings can observe and learn from nature well, can use flame heating to offset the differences in human physiological structure, but correspondingly to keep the body warm consumes less energy, more developed nerve centers like the brain to provide enough nutrients.

IQ is a very complex concept, including not only the ability to think, the ability to understand nature, but also the ability to adapt to society and other indispensable abilities for survival, and the form of species is diverse, and the way to adapt to the environment is very different, so the measurement of IQ cannot simply be measured by the number of legs.

Animals that feel like they walk on two legs have more developed brains. Two legs can have extra hands and get things that four legs can't get. Two-legged animals evolved more completely.

I don't think a two-legged animal is necessarily smarter than a four-legged animal. Take itWolves and ducksIn contrast, wolves are animals that understandof the groupFighting, there is a clear hierarchy, and the two-legged duck clearly does notThe wolf is smarterBright.

Answer: Pro, we will be happy to answer for you. In 1861, the Upper Jurassic limestone of Sorenhofen in the Bavarian province of Germany (i.e., the limestone formation formed in the late Jurassic) found the oldest bird fossil, not only the skeleton has been preserved, but also there are traces of feathers, it was named Archaeopteryx.

1. Birds are two-legged movements, and there are many species, second only to fish among vertebrates. In the 21st century, there are more than 9,000 species of birds known worldwide, and more than 1,300 species have been recorded in China alone. For example:

Ostriches, loomers, grouse, whirling woodfinch, rock pipits, wrens, peacebirds, great bustards, hairy-legged sandgrouse, sand larks, sand pengs, sand finch, parrots, grass owls, hornbills, biting cuckoos, broad-billed birds, eight-colored thrushes, peace birds, etc.

2. As artificially raised birds, animals are also two-legged animals, generally pheasants and ducks, such as chickens, ducks, geese, etc., and there are also birds of other families such as turkeys, pigeons, quails and various songbirds.

Summary. Hello dear, man is a higher animal, so in the process of evolution, man gradually walked upright, freed his hands, and since then, there has been a clear division of labor between hands and feet. Man began to walk on two feet, and his hands were used to invent and create things.

Why do humans walk on two feet while animals walk on four feet?

Hello dear, man is a higher animal, so in the process of evolution, man gradually walked upright, freed his hands, and since then, there has been a clear division of labor between hands and feet. Man began to walk on two feet, and his hands were used to invent and create things.

In order to use tools with free hands, man evolved to walk on two feet. Walking on all fours may still be monkeys, animals walking on feet, then it is possible that the forelimbs will degenerate, like the Tyrannosaurus rex, if the forelimbs are developed and the use of tools does not rule out the possibility of becoming intelligent creatures.

Greek mythology. The Sphinx, a sphinx in Greek mythology, once stood on the road and asked a riddle to passers-by. The content of the riddle is:

What kind of animal is it that walks on four legs in the morning, two at noon and three at night? The answer to the riddle is:"people".Morning, noon, and evening are metaphors for a person's childhood, middle age, and old age, respectively.

Legend has it that this puzzle was later answered correctly by the young Greek Oedipus, and the Sphinx committed suicide.
