Chapter 19: Descent with Modification Evaluate whether what we know about genetics supports Lamarck's theory of evolution. Describe the evidence about evolution and natural selection available at Darwin's time and now. Explain the observations that Darwin made and the conclusions that he reached from that evidence. Explain natural selection, artificial selection, convergent evolution, and homologous structures. Describe the scientific evidence supporting evolution by natural selection.

Evolution by natural selection, initially described by Charles Darwin, is the theory that explains how a population's inherited traits change over time and describes why organisms must adapt to their environments. Evolutionary theory can explain how specialized features develop in different species. - Explain what adaptations are and explain how adaptations relate to evolution - Explain what genetic mutations are and explain how they relate to structural adaptations and genetic inheritance - Explain what the phrase "natural selection" means and how it relates to evolution - Research and describe a detailed example of a species evolving (choose an example NOT discussed in the text)

Summarize the key points of Darwin's theory of descent with modification, including his proposed mechanism of evolution.
Review the kinds of evidence for evolution analyzed in Sections $2.1-2.5 .$ List the sources of evidence that were available to Darwin and those that appeared later. For example, of the evidence for microevolution discussed in Section $2.1,$ Darwin knew, and wrote, about divergent strains of domestic plants and animals and about vestigial structures. However, in Darwin's day no one had ever directly observed change across generations in natural populations. For each section, indicate which evidence you consider strongest and which you consider weakest. Explain why.
