Why are men taller than women, and why are animals more likely to be males?

Because of the influence of body structure, in the process of evolution, men often go out hunting, etc., through continuous exercise, men are taller than women, and animals can only obtain the right to reproduce each other if their bodies are larger than women.

Women have the skills to have children, so men have to occupy territory and make themselves evolve stronger. This is also the case with most animals in nature, where males can only make themselves stronger in order to have the right to reproduce in order to grab territory.

Whether it is male or female, or female and male animals, they all need to reproduce, and females usually give birth to offspring, while males have to bear a certain capacity, and the stronger the offspring, the better.

Fittest. Humans, like animals, are females who give birth to offspring, and males occupy territory and protect their homes. The taller and stronger the male, the more attractive it is to the female.

This is from the outside. Males do have more good looks than females in animals. Therefore, it is believed that males are generally prettier than females.

However, there is no such data for human beings, and there are more beautiful women and less men, so I think this is the idea.

Because that's the way it is, girls don't look ugly as long as they dress up.

There are many more, ants, praying mantises, spiders, bees, great white sharks, spotted hyenas, leopard seals, birds of prey ......

The animal with the largest difference between males and females in the world, females are 40,000 times larger than males.

The survival of wild animals in nature is not simple, almost every day and every minute there are potential threats, most species are not like lions and tigers, etc., are the top predators standing on the food chain, many creatures will be threatened by natural enemies, so they are still more vigilant in daily life.

But any species needs to reproduce offspring, which is the most essential pursuit of life, and this time is precisely the most dangerous moment for female beasts, because after mating and conception, they need to raise the fetus, and after giving birth, they need to be raised. Therefore, it can be said that the breeding and mating of organisms in nature has a great price, so they will be very "picky" in choosing their mates.

But in wild animals, it is not a two-way choice, it is generally a one-way choice, and the absolute condition of who is dominant is to see who pays the higher price for the offspring. This theory is called the parental investment theory, and the core of the theory lies in the word "investment". In some birds, for example, most of them are "temporary couples", and during the mating season, the males with bright plumage will dance or show their beautiful singing voices to attract the attention of the females.

If the females are satisfied with their performance, it means that the courtship behavior is successful, and a female and a male become a temporary couple, and when the mating task is completed, most of the time the male flies out of the nest and may go to find a new female for the next round of courtship, and the female needs to lay eggs and raise the offspring.

There is <> such a bird called the yellow-breasted weaver, they interpret the "scumbag" behavior to the fullest, the male is generally responsible for building the nest, when the breeding season arrives they begin to perform, and so on to attract the female to complete the courtship, the male yellow-breasted weaver will fly away from the nest and then build a second home, and carry out courtship behavior again, there are records that a male yellow-breasted weaver bird has three litters of offspring during the breeding period.

In fact, we can see that whether it is a combination of humans or wild animals, there will be a selection process, which will select more dominant individuals, so that their offspring can be inherited, while inferior individuals may not find a mate in the wild, and eventually the gene will end, and the existence of sexual selection has a positive effect on the development and evolution of species.

But for monogamous species, they are generally a two-way selection process, such as the emperor penguins in Antarctica, there is not much difference between male and female, and males do not need to rely on fancy appearance to attract female emperor penguins.

This is unfounded, I think there are many good-looking men and women, and there are many unsightly, and this percentage should be about the same, and it is a matter of genes to determine whether men and women look good or not.

I think it's because the direction of evolution is different, and the degree of evolution is also different.

No, as long as you keep a handsome batch. And women don't grow hair, and all the attacks must be good-looking.

Males are generally prettier than females in the animal kingdom, but humans are more beautiful than males, why?
