Contrast the significance of the cone of increasing diversity
withthe pattern representing decimation and diversification. can
youalso give an example of evolution at the phylotypic level
thatconforms to each of these patterns?

The history of human cultures is frequently marked by a distinctive pattern of evolution that paleobiologists term diversification and decimation. Under this process, fundamentally new socioeconomic systems appear during periods of dramatic cultural diversification,typically through cultural cladogenesis. Significant diversification episodes come about under conditions that favor group economic success under effective or geographic isolation.Typically short-lived, they are often followed by abrupt decimation under more competitive economic conditions. Regional archaeological sequences, viewed from this perspective, suggest that cultural evolutionary trends are strongly conditioned by historical contingency, though general evolutionary processes are continuously active; the emergence of new systems may be contingent on economic opportunities associated with niche reorganization; and severe competition such as that associated with demographic stress will generally favor decimation.

Explanation:

answer; i believe the answer is hydraulic action;

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat.   although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.
