Energy Due to motion of an objects is referred as kinetic energy and energy stored due to its position is called as potential energy. Therefore sum of kinetic energy and potential energy of an object is called total mechanical energy.
Total mechanical energy=KE+PE
The phenomeno is called risky shift. This phenomenon occurs when people make more risky decisions when they participate in group activities when they participate in activities individually. This is because the perception of risk is divided and diluted among the members of the group and therefore the perception of danger is lower.
I hope my answer can help you.
Natural selection is the change of a species traits and characteristics over time to adapt to its environment. Over a period of time, the species will change and evolve because of its changing traits to adapt.

Answer: Genetic Drift
Explanation: Genetic drift is an evolutionary mechanism whereby gene or allele frequency of a particular population change over generations due to random chance. The effect of genetic drift is most visible in small population due to reduction in population size resulting from natural disaster or splitting of a small group from the main population to formation a colony. However, it can occur in large population as well but it's effect is as strong as that occurring within a small population.
The genetic drift among the Dunkers could be attributed to the official split between conservatives and progressives members in 1882.
