Humans are not that different from animals but surprisingly show mixed behaviours, unlike other animal species. Are we even one species and not many subspecies pretending to be one? A cooperator engages prey both when it is alone or with a companion. Most common behaviour of extroverts. A cheater only engages when it is the first to find prey, but lets another individual make the kill if it arrives second. The author of the article in this case. Plenty of extrovert cheaters too pretend to read books by citing cliff notes. Ambiverts I suppose. A scavenger and a solitary hunter never hunts and waits for another individual to make a kill. A solitary avoids others and always hunts alone. Dangerous l33t hackers on the loose. Taken from https://doi.org/10.1086/284844 https://doi.org/10.1086/284844
