Just as detectives use fingerprints, DNA samples, and other evidence from a crime scene to speculate about what happened, scientists use observations of living species, fossil remains of ancient species, and a variety of other evidence to form and support the theory of evolution.
Many different scientists have contributed to the theory of evolution. Advances in fields of science such as paleontology, embryology, geology, and molecular biology all support and expand upon the theory of evolution based on natural selection proposed by Charles Darwin and Alfred Russel Wallace. Like with any scientific theory, scientists continue to review and expand on the theory of evolution as new data is revealed.
When you have completed this lesson, you should be able to:
1. identify early ideas about evolution
2. discuss theories that influenced scientific debate over evolution
3. recognize the major sources of evidence for evolution
4. recognize the pattern of features that reveal the history of a species

List two new traits (structural or behavioral) that each new species of rat might demonstrate as it adapts to the conditions on two of the four islands. choose only two islands that are described in the lesson. record the island latter and the major habitat feature of the island. then list two new traits each rat subspecies might demonstrate in order to survive the habitat on that island. note: new traits should be unique to that island and be in response to that island’s habitat feature. i cannot remember islands that were names in the lesson so only answer if you have done the lesson (5.13 life science 7b) choose 2 of the islands and describe a structural and a behavioral trait for a rat on each island so 4 total answers, 2 different structurals and 2 different behaviorals, one for each rat for each island
