What is the most frequent mating species?
Because of human limitations, a seven-day frequency is already extremely impressive. However, for lions, this number is still too low, they can reach 20-40 times a day, and up to 100 times, with each time only a few seconds short; nevertheless, So the question arises: How do they do it?
Why are lions so numerous?
The biggest reason why humans cannot achieve 20-40 times a day is that male humans lack a bone in a certain part that cannot be maintained by blood, While lions retained this bone during their evolution, so they can reproduce with females at any time.
Researchers discovered that this gene first appeared at the time when the placental and non-placental classes differentiated, that is, at the time of human ancient ancestors had this gene, but it was lost during evolution.
Later, people also thought that God didn't use Adam's rib to make women, but this bone. Of course, this is just a joke.
Lions not only have this bone, but also have spikes on the outside, these spikes are made of keratin, just like nails, about 1cm long. It is easy to imagine how painful it must be for the female lions.
When watching 'Animal World', you will find that lions are very attentive. When lions reproduce, male lions bite the necks of female lions. This is because the spikes on the male lion cause them pain. If not for the male lion biting them, they would run away.
Male lions' spikes can help them clear the reproductive cells left in the female lion during reproduction. At the same time, these spikes can stimulate the female lion's brain to induce ovulation.
Generally, it takes 4 or more times for female lions to ovulate, and the more times, the higher the chance of conception. Therefore, male lions try to interact with them as many times as possible.
After the female lion finishes, she will roll on the ground, which is believed to be helpful for conception.
Lion's development
Male lions' reproductive cells have a high rate of deformity, about 50% of them are malformed, some have multiple heads, some have two tails, and some have no movement ability.
Scientists believe that male lions' reproductive cells are so poor because of inbreeding. About 100,000 years ago, during the Ice Age, the number of lions was severely reduced, and the surviving lions had to choose inbreeding. Later, the number of lions increased, but the genetic diversity did not increase.
Lions are large carnivorous animals, but their number is small and their offspring survival rate is low. This is related to their food source.
On Earth, almost all biological energy sources come from solar energy, and some from geothermal energy. However, living beings cannot directly use solar energy, they need plants to convert solar energy into biological energy, and then energy can be transferred from plants to herbivores to carnivores.
Every time energy is transferred, energy will be consumed by 75%-95%. Lions are at the top of the food chain, so the total amount of energy is limited.
In addition, lions also compete with other predators, such as tigers and leopards, so that on Earth, the number of lions that can support is limited.
The number of lions represents the richness of genetic diversity. Because the number of lions is not enough, the genetic diversity of lions is not rich, which makes the extinction of lions more dangerous.
In summary, lions reproduce so many times a day because lions need to stimulate female lions to ovulate, and it takes 4 or more times to induce ovulation. The more times, the higher the chance of conception. Therefore, lions have so many times a day.
