According to the theory of evolution, if humans keep waving their arms, can they grow wings?

As we all know, evolution is the mainstream theory recognized by the scientific community, but at the same time, some people also put forward a strange problem.

If humans do nothing but wave their hands and imitate the flight of birds, will humans evolve wings in a million years?

It sounds like a ridiculous question, but before Darwin put forward the theory of evolution, many people believed it.

In the process of studying the evolution of natural organisms, there are two great men, one of whom is the world-famous biologist Darwin.

His theory of evolution not only changed the view of human beings on the origin of natural organisms, but also completely denied the view that human beings were created by God.

Another great man appeared earlier than Darwin. He was Lamarck, a French biologist. He was the first to put forward the theory of biological evolution and was the advocator and pioneer of the theory of evolution.

When it comes to Lamarck, I believe many people learn it from high school biology textbooks.

Although his theory of “using to advance, discarding to retreat” has been questioned, he provided the basis for Darwin and many other biologists to study biological evolution.

So why don’t organisms evolve now?

Take us as an example. Since apes evolved into humans, their appearance has been basically stable.

Is human evolution over?

In fact, this is not the case.

Human evolution has been slow. We are not only the evolution of appearance, but also the evolution of brain and heart. Although evolution is extremely slow, human beings have been evolving.

We will be like, “if humans keep waving their arms, can they grow wings?” This absurd and interesting hypothesis is based on Lamarck’s “use in, discard in” hypothesis.

The more you use a certain structure of the body, the more developed it will be. In fact, the theory of “using to advance, discarding to retreat” is wrong or untenable.

Let’s take the necks of giraffes as an example. Some people think that giraffes make special efforts to stretch their necks in order to survive and get leaves from trees.

Because the more frequently used organs are used, the more developed they are, and the traits obtained in this way can be inherited, so that the neck will gradually grow over the generations. This is the saying of “use to advance, discard to retreat”.

But from the perspective of Darwin’s “natural selection”, giraffes live in the Savannah, with leaves concentrated in the upper layer. The longer their necks are, the more food they can get. The shorter their necks are, the more food they can get. The life they can get will last, while those who can’t get will be gradually eliminated.

Birds, for example, can be said to be the most successful flying animals on earth, they rely on feathered wings to fly.

But from the earliest point of view of birds, their longer forelimbs and feathers were not born for flying. The longer forelimbs were for climbing trees, while feathers were for keeping warm.

But as their forelimb feathers continue to grow longer, some birds begin to learn to glide, and over time, they will fly. Because birds have to learn to fly with their wings to adapt to the air environment.

But for human beings, even if our arms are always waving like birds flying or propellers every day, it can only produce the effect of stronger and longer arms, but can not grow wings.

Because we don’t need to evolve wings to adapt to the environment, and we don’t have any motivation to evolve wings.

If we have to grow wings, maybe we can only realize this “dream” by finding a way to change the genetic nature of species and mutate genes, or by means of future science and technology.

Xiaobian believes that in the actual evolution, only the most adaptable physical characteristics can survive better and pass on their own genes.

The lengthened forelimb has no advantage in human society, on the contrary, it will consume limited energy, resulting in the individual being at a disadvantage in the competition and eventually being eliminated.

So even if someone is really bored with flying and always waving his wings, he will not grow wings. At most, his forearm flexibility will be improved, and he will suffer from periarthritis of shoulder too early.
