Pride is the group of Lions. Pride is the community of lions composed of one single male lion and several females where they live and reproduce.
As the male of the pride grows old, it is taken by another male lion who is younger. Then, the younger lionkills the cubs of the previous male, just to ensure that those genes are nottransferred to future generations. Also, during the females feeding the cubs, they can’t reproduce due to lactational amenorrhea. Killing the cubs makes the females free to reproduce again.
Pride is the social community of lions where they grow, mate, reproduce, communicate, hunt etc. When male lions gets control of a new territory or a pride, they most of the times kill the cubs of the pride because they are not biologically related and do not want to waste their energy by ensuring that the cubs genes are passed on.
They don't want to be stepfathers. Female lions also will not be responsive to mating during the time they are feeding, so killing the cubs allows the male lions to reproduce.
