Document Summary
Identify the meanings of kin selection, altruism, reciprocal altruism, eusocial. Competitive altruism: individuals actually compete with each other to be more cooperative. Longer lived species are more likely to develop cooperative behaviour than shorter- lived ones. Nephew/ neice and aunt/uncle. Identify why haplodiploidy can favour high levels of cooperation in social insects. In bees and other eusocial insects, sex is determined genetically through haplodiploidy. Female bees are diploid because they receive a set of chromosomes from each parent. The high degree of relatedness among workers in some colonies of eusocial insects may explain their level of cooperation. Spite: both the actor and the recipient suffer a reduction in fitness. Altruism appears to be widespread through the animal kingdom: behaviours that are, or are not, altruistic . In many species such as king penguins and bengal tigers there is a phenomenon known as parental care. Parental care is not considered to be altruism but rather cooperation.
