According to the extended evolutionary synthesis, parents who teach their young at a particular behavior that aids in their evolutionary success are practicing kin selection. This form of natural selection occurs when close relatives share genes and helping a close relative increases the chances of passing on one's own genes. An example of kin selection is when a parent teaches their young to migrate for better chances of survival.
