This kettle lake forracd 14,000 years ago when a glacier that covered the surrounding area melted. Initially devoid of animal life, over time the lake was colonized by Invertebrates and other animals. Hypothesize how mutation, natural selection, genetic drift, and gene flow may have affected populations that colonized the lake.

Adaptive radiations can be a direct consequence of three of the following four factors. Select the factor that is NOT a direct consequence of adaptive radiation. Select one: a. Genetic drift b. Vacant ecological niches (niches are environment "space" where a particular organism has resources required to survive and reproduce) c. New evolutionary innovations d. Colonization of a new region that contains suitable habitat and few competitor species
Is the following statement consistent with the provided data?  Answer TRUE if the statement is consistent with the data.Answer FALSE if the statement is not consistent with the data.  1. The evolution of freeze tolerance involves some factors that were not shaped directly by natural selection. 2. Because of their freeze tolerance, wood frogs may colonise more of the remainder of the island of Newfoundland than the leopard frog. 3. The distribution of the wood frog and leopard frog supports character displacement as a plausible hypothesis for why they overlap.
