Humans and vampire bats are both mammals but are very different from each other. Both do live in large groups and both practice altruistic behaviors. Altruistic behaviors are behaviors that increase another individual’s fitness at the cost of one's own fitness. Vampire bats go out at night and feed on blood, they have been observed to feed other bats that are not related to them. They will feed other bats, but the behavior is a give and take. Bats only feed other bats that have fed them. Haplodiploidy is not relevant here, humans and bats are diploid. Chiroptera is the group that contains the bats, humans are primates. The feeding is not based on kinship; it is based on concept of reciprocity. If you scratch my back, I’ll scratch yours.
