The mating habits of animals are always strange. Some animals mating relatives do not recognize and return to with their family members .
Backcross between dogs
People will inevitably think, is the same as the lion standing at the top of the food chain? What behavior will a wandering lion do when it grows up when it meets its mother?
Animals that do not recognize relatives mate
Animals in nature have a strong sense of mission to reproduce and reproduce. In order to inherit genes, they will use various means to mating.
Some species have started to act as "Lao Wang next door" , mixing their sperm cells into the female's "sperm bank", and letting the other party reproduce for themselves without knowing it.
Some use group mating to make the sperm and egg cells fully contact and increase the probability of female fertilization.
Humans and most animals are from this
Among all mating forms, there is one mating method that is the most harmful. This mating method is inbreeding , and species will consciously avoid this breeding method.
However, in special circumstances, inbreeding is a means that must be used.
1908, there were only 13 Asian lions left. In order to prevent this species from extinction, people captured all wild Asian lions and kept them artificially. During the reproduction and mating process, because the number was too small, people had to use inbreeding methods.
In 2008, the number of Asian lions increased to 350, but the genes of these Asian lions have gradually deteriorated, have low risk resistance, and are easily troubled by diseases and other problems.
Lion around the world has a slight difference in appearance
This is the harm brought by inbreeding. Although it can barely allow the species to continue, it can easily lead to the species decline .
In fact, for these Asian lions, even if human intervention in , they will choose inbreeding when the species is at the end.
Lions and in-kins
Lions are a group of people among a few large predators. They are usually led by the Lion King to establish a lion group of 8 to 30 lions.
In the lion group, although the Lion King is the absolute overlord, the number of females is far more than that of males. These females are basically the Lion King's "concubine" .
"Concubines" take into account the hunting and raising of lion groups, and will take good care of every descendant in the lion group, even if the descendants are not their own.
, while male "child" must leave the lion group and live alone. Even if it does not want to leave, parents will force the child away with coercive means.
The male lions who leave the lion group will temporarily wander for a while, because the male lion's sexual maturity age is around 5 years old, and the male lions who have no desire to mating will not look for a new lion group for the time being.
Lion: I have principles
At the same time, the male lion usually runs far away from the lion group and activity area where their parents are located, which is to avoid back-crossing with their family after they are sexually mature.
These male lions usually train themselves in the wild. When they have enough competitiveness , the wandering lions begin to look for the lion group and duel with the Lion King among the lion groups.
When the wandering lion wins, the old lion king leaves the lion group and becomes the new stray lion. The new lion king takes office and has the mating power of all the females in this group.
The process of fighting for mating rights in nature is bloody and violent
If there are cubs of the old Lion King in the lion group at this time, the new Lion King will kill them without hesitation.
Therefore, in order to protect their children, some lionesses choose to leave the lion group and live alone . When the child is about 2 years old, the lioness bids farewell to the child and then looks for a new lion group.
What to do if you meet your mother?
Some male lions may get lost while wandering, and after sexual maturity, they accidentally bumped back into the original lion group.
It is also possible that after the male lions wander, the original lion group just migrated to the place where the male lions wandered.
At this time, the lion meets his mother again, and the lion has just reached the stage of sexual maturity. Will the lion return to with its relatives?
The male lion in the middle of life
The answer is The affirmative . At this time, the male lion is likely not remembering his original ethnic group and challenging his old father.
Once the challenge is successful, the young lion will stage a tragedy of " Oedipus " in the lion group.
The difference is that this young lion will also include his own sister and sister in the "harem group" and even kill young brothers and sisters.
Of course, if incomparable behavior occurs only in the first generation, the impact of on lion offspring is not so significant, and the probability of backcrossing is also very low.
lioness group
The consequences of inbreeding in animals are different from those of humans. As long as inbreeding is not adopted for multiple generations, there will be no malformed fetuses, or the phenomenon of inducing multiple infectious diseases.
lion group can also be effectively continued, but the next generation of genes cannot be improved and evolved.
For animals, there is no moral concept accusation, they don't need to think too much about it.
But if the next generation continues to breed inbreed, its harm will gradually become prominent.
"The Lion King" clip
The lion also realized the problem of the lion cubs "usurping power", so they kicked out the adult lions in the lion group.
Since the stray lion may return with his mother, is it possible for the young lionesses who stayed in the lion group to return with their father?
Female lions reach sexual maturity at the age of 2 to 3 years old and can go into estrus throughout the year.
There is a clear time for male lions to have a estrus period. Their estrus period is in spring and autumn seasons, and usually lasts 4 to 5 days.
Reproduction and offspring. Animals spare no effort
Under the strong desire for mating, if the status of the Lion King cannot be shaken for a long time, it is not impossible for the father and daughter to intersect, but the probability of such a situation also is not high.
Because the competition in the lion group is very cruel, many lion kings are often replaced by stronger lions before their butts are hot.
The bigger the lion group, the harder the Lion King's throne will be to sit firmly. Once the Lion King's body has abnormal problems, its throne may be replaced, and the old Lion King's descendants will not be able to survive.
In addition, the competition between lion groups is also quite fierce. As the strongest existence among lion groups, the Lion King is the main combat force of lion groups conflicts and the "thug" responsible for lion groups conflicts.
If you want to carry the crown, you must bear the weight
So, don’t look at the Lion King’s usual carefreeness, but once something happens, the Lion King must resist it.
In the cruel competition among lion groups, the adult rate of lion cubs is only about 30%.
When the Lion King loses his throne, what he ushers is the ruthless Wandering Life .
Unlike the wandering when they were young, the elderly lion lacks food during the wandering process, and its elderly body is difficult for them to support them to prey on medium and large herbivores.
In order to make your elderly life easier, sometimes several elderly lions will gather to form an "Sunset Red" organization.
Everyone works together to hunt and cross the last years together.
lions do not live long among beasts, but also lose to cats
Some elderly lions have a sense of arrogance in their hearts and do not want to cooperate with other lions and choose to live their lives alone.
Most of these lions starved to death in the wilderness miserably.
Tigers also don’t recognize their relatives
In nature, another creature standing at the top of the food chain - tiger , also doesn’t recognize their relatives when mating.
Unlike lions, tigers are solitary animals and do not form their own "harem group". Instead, they look for mating partners during the estrus period, and leave after they finish, leaving behind a romantic debt.
Lion and tiger can also mate
For tigers in estrus, it doesn’t matter whether they have blood ties. What’s important is whether the other party can mate with themselves and pass on their offspring.
