Although a King of the Steppe, Lions Harbor Numerous Troubles
For humans, seven times a day is already a remarkable number. However, for lions, this number is still too little, they can do 20-40 times a day, and up to 100 times, the time is just a little shorter, only dozens of seconds.
So the question is, how do they do it?
Why do lions have so many times?
The biggest reason why humans can't do 20-40 times a day is that male humans don't have a bone in a certain part, they can only rely on blood to maintain hardness.
While lions retained this bone during evolution, so they can reproduce with females at any time.,
Researchers found that this gene first appeared at the time when the placental and non-placental animals differentiated, that is, at the time of human's distant ancestors had this gene, but it was lost during evolution.,
Later, people also thought that: God didn't use Adam's rib when he made women, but this piece of bone.,
Of course, this is just a joke.,
Lions not only have this bone, but also have spikes outside, these spikes are made of keratin, which is the same as nails, about 1cm long, just looking at the picture can imagine, during the process, the female lion was very painful.,
When watching 'Animal World', if you pay attention, you will find that lions bite the female lion's neck during reproduction, this is because the male lion feels pain from the spikes on its body. If not for the male lion biting them, they would run away.,
Male lions' spikes can help them clean the sperm from the previous lion in the female lion's body during reproduction. At the same time, these spikes can stimulate the female lion's brain to induce ovulation.,
In general, it takes 4 or more times for the female lion to ovulate, and the more times, the higher the chance of conception, so male lions try to reproduce with them as many times as possible.,
After the female lion finishes the process, she will roll on the ground, which is said to be good for conception.,
Lion's development
Male lions' sperm quality is poor, about 50% are abnormal, some have multiple heads, some have two tails, and some cannot move at all.,
Scientists believe that male lions' sperm quality is poor because of inbreeding. About 100,000 years ago during the ice age, the number of lions was sharply reduced, and the surviving lions had to choose inbreeding. Later, the number of lions increased, but genetic diversity did not increase.,
Although lions are large carnivorous animals, the number of lions is small and the survival rate of cubs is low. This is related to their food sources.,
On Earth, almost all sources of biological energy come from sunlight, and a small part comes from geothermal energy. However, living beings cannot directly use sunlight, they need plants to convert sunlight into biological energy, and then energy can be transferred between plants-herbivores-carnivores.,
Every time the energy is converted, the energy will be consumed by 75%-95%, and lions are at the top of the food chain, so the total energy is limited.,
Furthermore, lions have to compete with other predators, such as tigers, leopards, etc., so that on Earth, the number of lions that can support is limited.,
And 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.,
Summary
Why lions reproduce so many times a day is because lions need to stimulate the female lion to ovulate, only continuous stimulation of 4 or more times can induce ovulation, and the more times, the higher the chance of conception, so lions reproduce so many times a day.
