Why Humans Can Mate Freely While Animals Need a Breeding Season?
At a glance, words like 'mating', 'breeding season' seem somewhat vulgar, but one must admit they represent the most fundamental level of scientific understanding, because for many animals, mating is essential for reproduction, including humans.
What is the breeding season?
The breeding season actually refers to the period when animals are willing to mate, until they refuse to mate. It is a special physiological period in which animals begin to be willing to accept mating and end when they refuse to mate. Generally, the breeding season of animals is a relatively fixed time period throughout the year.
And usually, the breeding season is mainly manifested in mammals and birds, where female animals in a specific season are the reproductive cycle of female animals in mammals and birds, namely, in terms of behavior, they attract and accept males, and in terms of physiology, they prepare for ovulation and fertilization.
For example, there are many typical examples, such as the meowing of cats at night, which is the female cat calling for males; the peacock displaying its beauty with its feathers, which is the male peacock attracting female peacocks.
Why do animals have a breeding season?
In the above, the breeding season is mainly the female animals of mammals and birds accepting the mating of male animals. Animals have a breeding season mainly because of the long-term evolution in order to adapt to the natural environment gradually formed a specific rule.
We all know that most mammals are in the winter and spring (the period from December to early March), they start to mate and reproduce, this is mainly because the gestation period of animals is generally about 6 months, so the young are produced mainly in the summer and autumn (when there is plenty of water and the temperature is high), and with sufficient food sources and high temperatures, the young can be well-protected and survive, so as to ensure the animal population and the normal reproduction of the species.
IfMammals choose to mate in winter and springthen for some animals, especially the bottom-chain animals like insects, they usually choose to mate in summer and autumn, besides food and temperature, it's also related to avoiding predators, because insect eggs hatch about 3 weeks, first, the vegetation in summer is abundant, and the larvae are easy to hide and survive, second, in autumn, the predators of these insects, such as frogs, snakes and some birds, some of them hibernate, and some migrate to the south to survive the winter, so the number of predators is reduced, which is also conducive to the reproduction of the species.
From the above content can be concluded thatAnimals choose to mate at a certain period is related to climate environment, the difficulty of obtaining food and the number of predators, but animals have a breeding season is mainly to release specific signals to attract and accept males.
As we know, animals like tigers are generally solitary and have strong territorial behavior, usually a tiger's activity range is about 100-400 square kilometers, and in some areas with limited food, it can even reach 900-1000 square kilometers. Therefore, for tigers, if the female tiger and male tiger live in the same area, it will inevitably expand the hunting range, which is obviously not conducive to the survival of tigers.
Since the same area food is limited, so only in the breeding season, female tigers and male tigers live together, andThere is an unspoken rule in the tiger world that male and female tigers always live next to each other, which is very helpful for tigers, for example, when the breeding season comes, in order to attract male tigers to matefemale tigers are very loud during the breeding season, and the sound can reach 2000 meters, which can attract the attention of male tigers.
It is worth noting that tigers generally mate from November to early February the next year. Generally, the gestation period of tigers is about 100 days, and the lactation period is about six months, and the mother tiger and cubs live together for two to three years, so during this period, the female tiger will not mate, thereforeThe breeding cycle of tigers is generally 2-3 years
Given the long breeding interval of tigers and the natural lifespan of tigers is generally 20-25 years, so theoretically, a female tiger can mate and breed up to 8-10 times in her life, and each time she usually gives birth to 2 cubs, this is also one of the reasons why tigers are easily threatened as the king of the forest.
Why don't humans have a breeding season?
In fact, it's not just humans who don't have a breeding season, many social animals on earth also don't have a clear breeding season, this is besides the relationship with the natural environment, also depends on whether they can modify and utilize the natural environment.
Unlike humans, animals can only adapt to the environment and survive and develop in harsh environments, so they can reproduce in harsh environments, but humans are higher animals, have brains, and are good at making and using tools, such as knowing the cycle of the four seasons and arranging spring plowing, summer planting, autumn harvesting and winter storage, and in a relatively limited area, they can produce more food.
