(See Lessons) Life forms have changed over time. Many life forms have gone extinct. (See Lessons) To help you teach these concepts, you may want to explore Patterns. Return to Top Evidence of Evolution Concepts Today there are many diverse forms of life. (See Lessons) Living things are alike in some ways and different in other ways. (See Lessons) Plants and animals have features that allow them to live in various environments. (See Lessons) Form is linked to function. (See Lessons) Fossils provide evidence of past life. (See Lessons) To help you teach these concepts, you may want to explore Lines of Evidence. Return to Top Mechanisms of Evolution Concepts Living things have offspring. Offspring inherit many traits from their parents, but are not exactly the same as their parents. Siblings are similar to, but not identical to, one another. There is variation within a population. (See Lessons) To help you teach these concepts, you may want to explore Descent with Modification or Natural Selection. Return to Top Nature of Science Concepts Scientists ask and address questions about the natural world. Science explains the natural world using evidence from the natural world. We learn about the natural world using our senses and extensions of our senses. (See Lessons) To help you teach these concepts, you may want to explore Nature of Science. Return to Top Studying Evolution Concepts Scientists study living things. (See Lessons) Scientists study rocks. Scientists study fossils.
