Chapter 23, Problem 9TYU
SYNTHESI2E YOUR KNOWLEDGE
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.

Applying your knowledge of genetics, natural selection and evolution, how is the positive response to global climate change possible? Is your answer supported by the information from the article “Can Evolution outrace Climate Change”? According to the authors of this article, what are the conditions necessary for an organism to evolve to accommodate climate change?
MAKE CONNECTIONS Human actions are causingclimate change, thereby affecting Earth’s ecosystems—few of which have been affected as greatly as those in theArctic. Hypothesize how climate change might cause evolution in arctic tundra populations. Explain
