What is inclusive fitness?

Inclusive fitness provides evolutionary explanation of altruistic behavior between animal communities. When we think about "survival of the most suitable", we combine selfish behavior with organisms that always try to live longer and more successfully reproduce. Inclusive fitness, however, takes into account close genetic relatives in a larger mission of passing conventional genes, rather than only the genes of one organism. The foundations of Darwin's evolution are not violated. Perhaps he was considering colonies of ants where sterile workers work infinitely in favor of the queen and colony in general, without the hope of reproduction. Did it not be the fundamental principle of evolution that the aim of the organism is to live long enough to reproduce, and that reproducers represent the strongest of the group?

instead of Restrihamilton, which performed the urge to reproduce only its exact genetic code, has expanded its urge to include behavior that would allow genes to pass closely with it. This means that animals are acting first to protect but also act tAK to protect their closest family members such as parents and siblings because they share some of their genes. In rare circumstances, his behavior will be protected by other relatives, such as cousins ​​and siblings of parents. When the costs do not exceed benefits, we observe the so -called altruism in many animal communities, which is better explained by inclusive condition.

For example, PSI prairi will cooperate in searching for predators. If one sees a snake, it will be a warning that the others can cover. Although the noise, however, the dog dog actually draws attention to itself and the snake is more likely to attack it. Intusive Fitness makes sense to this non -intuitive behavior by pointing out that the relatives of dogs dogs, those who share many of its genes, will have the advantage of surviving and reproducing. In this sense, "fitness" means the probability of genome, a collection of genes to pass on Dalies generation.

those who study inclusive fitness have developed a handy equation that shows when the cost of altruism is doing or overcomes over benefits. R means the rate of affinity of two individuals. R is higher when they are closely related, such as the whole siblings, and lower when they are remote relationships. C is the price for individuals, if it risks behavior presented as the likelihood of not reproducing. Finally, B is a number that measures the benefit that provides an altruistic act to the recipient. Thus, if it is greater than zero, the animal is "altruistically" on behalf of the inclusive fitness.
