They argue that the bright appearance of the male is not yet proof that there are few females in the population.
Old man Darwin was wrong. Scientists from the University of Bath in Great Britain came to this conclusion after long and painstaking research. They almost fulfilled the dream of many scientists who tried to catch the founder of the theory of evolution at least on something, convict him of incompetence and turn the theory itself to dust. British experts tried to pull one brick out of the fortress created by the legendary man who so irrevocably exalted the monkeys, and perhaps they really succeeded.
So what did the British notice? They found out that Darwin was wrong in the theory of natural selection, which says that vivid sex characteristics increase the chances of an animal getting a mate. According to the evolutionist, the fewer females, the more pronounced the appearance of the male, which competes with rivals, should be. However, new evidence shows that this is not the case. Take peacocks for example. The more luxuriant the tail of the male, the easier it is for him to bypass competitors. But the females in this population are not in the majority. So there is no particular point in showing off before them. Each creature will still have a pair.
Scientists have examined with particular awe the sexual size dimorphism (when males are larger than females) in 462 animal species, including baboons and elephant seals. Large size allows males to dominate rivals in the fight for the female. However, the most intensive sexual selection, as it turned out, occurred in species with an abundance of females. Here it is, the inconsistency. There are more than enough females, but there is still competition between males, they find out who is cooler than whom. It turns out that this happens in populations where males have harems for themselves. In fact, the winner gets the opportunity to fertilize a large number of females, and as a result, small males cannot give offspring at all.
In a word, even where ladies are the predominant number, there is still a rivalry between gentlemen.
However, the zoologist Yevgeny Abizov believes that there is no obvious contradiction between the conclusions of Darwin and the conclusions of the British.
– Darwin always repeated that evolution is impossible without competition. That is, there should be competition “in any case”. And the concept of beauty, by the way, is also quite relative. If proportions seem beautiful to a person, then for an animal, it is quite possible that something disharmonious is more interesting. There are no proportions in nature, but there is a vector of striving.
