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 ...
Infanticide in non-human primates occurs as a result of exploitation when the individuals performing the infanticide directly benefit from consumption or use of their victim. [1] The individual can become a resource: food ( cannibalism ); a protective buffer against aggression, or a prop to obtain maternal experience.

Children are taken from their parents immediately after birth and submitted to a highly competitive selection process while being raised in public "crèches".
A lack of sleep is not only dangerous to the health of humans but it also puts the health of these animals at risk, no matter their shape, size or species. ... much sleep particular animals ...
Sleep can follow a physiological or behavioral definition. In the physiological sense, sleep is a state characterized by reversible unconsciousness, special brainwave patterns, sporadic eye movement, loss of muscle tone (possibly with some exceptions; see below regarding the sleep of birds and of aquatic mammals), and a compensatory increase following deprivation of the state, this last known ...

Infanticide (or infant homicide) is the intentional killing of infants or offspring. Infanticide was a widespread practice throughout human history that was mainly used to dispose of unwanted children, [1]: 61 its main purpose being the prevention of resources being spent on weak or disabled offspring.
The pressure to stay alive eliminated the genes needed for long life. Citing reptiles and other animals with a much slower biological aging process than mammals, de Magalhães hypothesizes that ...
