Document Summary

Advantages and disadvantages of living in a group: advantages: Groups of cooperating predators capture prey more effectively. Groups of defense have more watchful eyes/ears and more lures. It might be someone else that gets captured rather than you: disadvantages: May facilitate the spread of contagious diseases and parasites. Meaning and dominance hierarchy, kin selection, altruism, recirprocal altruism, eusocial, haplodiploidy: dominance hierarchy: when members of a group interact and create a ranking system. Sometimes only dominant individuals reproduce: kin selection: individuals are more likely to help close relatives, altruism: helping another individual.

Favoured by natural selection as long as cheaters are denied future aid: eusocial: when single female produces offspring and nonreproductive individuals help. Males haploid (hatch from an unfertilized egg) Identify why haplodiploidy can favour high levels of cooperation in social insects. In haplodiploidy, males are related to each other by an average of 75%
