For each of the following situations, determine whether the population is in Hardy-Weinberg equilibrium or is evolving. Choose the correct status for each population. A group of birds is blown from the mainland to a small island during a storm. They remain there and develop into a new population. A population of humans lives in a secluded community and tends to intermarry within their own group. Occasionally they bring in young people from communities in other areas. A large forested area has remained relatively untouched for thousands of years. The population of red oak trees has not been subjected to any known diseases or other environmental stresses. In a rain forest, several populations of a monkey species coexist relatively close to each other. Each population has its own range, but mating sometimes occurs between adjacent populations.
