This provides an advantage to the male because the female will more quickly copulate with him and raise his young rather than the young from the previous mate; his fitness increases through use of infanticide. Infanticide in one-male breeding units has also been observed in red-tailed monkeys [11] and blue monkeys. [12]
Infanticide not only reduces intraspecific competition between the incumbent's offspring and those of other males but also increases the parental investment afforded to their own young, and allows females to become fertile faster. [12] This is because females of this species, as well as many other mammals, do not ovulate during lactation. It ...
Mothers provide their young with food, warmth, and protection, and teach them certain skills. In addition, a chimpanzee's future rank may be dependent on its mother's status. [107] [108] Male chimpanzees continue to associate with the females they impregnated and interact with and support their offspring. [109] Newborn chimpanzees are helpless.
A new study describes the first case of an adult male chimpanzee being observed snatching, and then eating, a newly born member of the group.
Chimpanzees have full mouth-to-mouth contact, and bonobos kiss with their mouth open and mutual tongue stimulation.

Altricial birds are less able to contribute nutrients in the pre-natal stage; their eggs are smaller and their young are still in need of much attention and protection from predators. This may be related to r/K selection; however, this association fails in some cases. [18] In birds, altricial young usually grow faster than precocial young.
