Filial piety has three, no queen is greater, this is the ancestral precept handed down from the ancestors, but also reflects the importance of human beings for future generations, now with the development of society, freedom, human rights and other concepts are more and more deeply rooted in the hearts of the people, "live for themselves" has become the motto of more and more young people, more and more young people choose to do Dink, want to live for themselves for a lifetime, not bound by families and children.
But for animals, they are far less thinking than humans, and mating and heredity remain their most important missions in life. In the animal world, there are no legal sanctions or moral constraints, they are often polygamous, so how can mating priorities be obtained in fierce competition? And how to ensure that the child born is your own?
Let's take a look at what animals have done in the fierce male competition to be able to have their own offspring.
01: Get priority mating rights
If you want your genes to be inherited, the first step is naturally to obtain mating rights, and there are many ways for animals to attract the opposite sex.
The first is to get the heart of the opposite sex through a beautiful appearance. Deer and dolphin fangs were originally straight and sharp enemy weapon, and later due to the lack of natural enemies in the living environment and abundant food, so full of warmth and lust, their fangs gradually bent, because the better the shape of the fangs, the more they can get the favor of the female deer dolphin, in order to obtain preferential mating rights, the former enemy weapon slowly became a courtship flower gun, because the bending is too strong, eventually the fangs will stab themselves, and even insert their own eyes, burying their lives. Deer dolphins are typical animals that use their lives to seduce their sisters. There are many animals of the opposite sex that attract with their appearance, such as peacocks, birds of paradise and other birds, and they will attract the opposite sex with beautiful feathers.

The second is to defeat the opponent through a strong physique. This category is also the most common, such as tigers, lions, walruses and other more powerful animals are through absolute strength to obtain preferential mating rights, they use their strength to defeat competitors, obtain their own territory, but also get the mating rights of all females in the territory.

The third is the spelling skill. In order to gain the favor of the female, the gardener bird must go to great lengths to build a house: the courtship pavilion. This kind of "courtship pavilion" has a complex structure and is decorated with great "taste". But it is not enough to have a room, they also have to be talented, the male bird must be able to sing, dance, shake the butt to show the female bird, when the female bird is attracted by his talent and slowly approach, its opportunity comes.

For a european dance fly, if the male wants to capture the heart of the opposite sex, it is impossible without gifts. After catching a small fly, the male will dance in front of the female and give it as a gift to the female. Smart males also wrap gifts with small silk balls, and when the female unpacks the gifts to enjoy, the males will take advantage of the opportunity. And the male also knows how to cherish the fruits of his labor, and some miserly males will return the gifts that the female has not yet eaten after the work is finished, and then give them to the next lover. Some cunning males have no gifts, but use an empty gift box to deceive the female's feelings.

02: Uniquely constructed tintin increases the success rate
Just because you have the right to mate and mate successfully doesn't mean that your baby is necessarily yours, and for polygamous animals, it is likely that the female has been intimate with other males before you. As a result, some animals have evolved multifunctional tintins, which can not only transport their own genetic material, but also clear the genetic material of their competitors.

The flat-headed brother (honey badger) is a kind of animal that is not afraid of heaven, daring to treat poisonous snakes as spicy strips, and also daring to fight with lions and leopards, looking like a second son. But in the internal competition between the same sex, they do not fight each other to death, but have evolved a spoon-shaped tintin bone, which makes its tintin like a water scoop, able to clean up the genetic material of other animals.
Felines have similar skills, such as cats, tigers, lions, tintin is covered with small barbs 1-2 mm long, like wolf's tooth sticks, although these small barbs will make the female cat extremely painful, but for the male cat is beneficial and harmless. Not only can barbs stimulate ovulation in the female cat, which allows it to fertilize and produce fertilized eggs, but more importantly, it can also be used to clean up the genetic material left in the female by other male cats.
03: As long as the little tadpole runs faster, others can't catch up with me
Some animals have not been able to evolve the "green hat" Tintin like flat-headed brothers and felines, but they choose to make a fuss about small tadpoles, and they win the priority union with eggs in the race by making the small tadpoles run faster.
The sperm head of the Kobayashi mouse (a type of mouse) evolved a hook-like structure that allowed them to wrap around each other to form a long sperm "train", which traveled much faster than a single sperm, just like it was opened and hung, and the fast running train was able to enter the station (egg) first, grabbing the only parking space.
Female desert ants have an organ called seminal vesicles, and only those sperm that enter the seminal vesicles have a chance to be fertilized, so in order to be able to enter before the seminal vesicles are full, the male ants have evolved highly cooperative sperm, which form a combination of 50-100 cells, swimming much faster than alone, so they can increase their winning percentage.
summary:
Animals can be said to have their own genes to be passed on, and the meaning of many animals seems to be to reproduce. Compared with animals, human beings are now monogamous, and human society has moral constraints and legal sanctions, men want to inherit their genes, to prevent the intervention of the old king next door, the best way is naturally to take care of their wives, earn more money, give the future baby enough material conditions, so that the other half will have enough sense of security, after all, "money" system is sometimes more effective than self-control.
