Prior to European colonization, tens of thousands of whooping cranes lived in North America. By 1938, due to overexploitation and habitat loss, whooping cranes were virtually extinct, with a total population of only 15 individuals. Since then, careful conservation efforts have increased the North American whooping crane population to over 800 today. From a genetic standpoint, as a result of this catastrophe, whooping cranes experienced a “population bottleneck”, which is a severe form of . The current population of whooping cranes should be expected to have , relative to the pre-colonial population.

A study on grooming among vervet monkeys has shown that individuals who groom other unrelated individuals are more likely to get a response from those they’ve groomed when they call for aid. This observation supports the hypothesis that this social behavior could have evolved by way of…
