Guys do not need 10 examples of wildlife
• The men do not need 10 examples of wildlife
Yes, it happens in nature, such that there is no need for females to males. They do an excellent job, and with women and with men's responsibilities. Such "virgin birth." Do not believe me? See for yourself)
It called a "virgin reproduction" parthenogenesis. It takes place in such a way that the female sex cells develop independently in the body females without fertilization. It is believed that there was this kind of breeding in the evolution of dioecious forms.
The genus includes 20 of these lizards, bisexual and gay 7 species. In fact, in vertebrates, parthenogenesis is rare and these lizards - one of the few representatives of this phenomenon.
tardigrade - the neubivaemy type of invertebrate. Sneeze they would like to change the temperature, a strong X-ray emission, open space ... I think they - the only ones who can survive the present apocalypse. So guys do not need them. Though tardigrades have males, but they occur rarely, because parthenogenesis have well developed.
The London Zoo and Chester England observed, in the absence of males, females lay eggs from which the offspring appeared. The ability to reproduce such a Komodo monitor lizards can be explained by the need for forced female to found new colonies, when during a storm washes away their neighboring islands.
For two consecutive years, appears in the female offspring zheltobryuhoy a water snake, which lives in the environmental downtown Cape Girardeau, Missouri. The last time she saw eight years ago, so here is another example of the virgin breeding.
Most aphids lay eggs, some species typical of a live birth. But fertility in almost all kind of happening via parthenogenesis. Individuals who have wings, are often forced to develop new colonies, and because this type of breeding them is very convenient.
The other species of termites reproduction takes place in a conventional manner.
A lot of bees from unfertilized eggs develop into males - the drones and the fertilized appear uterus and worker bees.
And if you moisten them, they repair themselves, by their inclusion in the DNA of genes of organisms eaten, because they were many years can go without sexual reproduction.
In 2001, Henry Doorly Zoo Hammerhead produced offspring after a long stay in the water tank, where there were no males. Just when DNA analysis confirmed the presence of only maternal cells calf material.
As populations that reproduce this strange way have been found in some species of cockroaches, ants, fish, birds (including chickens).
