Evolution can be supported by the lines of evidence which are presented in this resource. Recognize these lines: fossil evidence, homologies, distribution in time and space, and evidence by example.

Understanding Evolution provides evidence for evolution using fossils. There are also links to lesson plans.

Find out how fossil evidence has been the major link to learning about Earth's geologic history. See several illustrated interpretations of a geologic time scale in this online biology textbook.

Students hear a story as they "find" bones that you have put in an envelope for them. Their job is to begin assembling the bones as best they can. The students will invariably come up with different configurations--just like scientists...

Charles Darwin's theory that all living organisms are connected in some way has been confirmed through intense studies over centuries. Understand the similarities that bond all things living to the same family tree by checking out this...

This in-depth article illustrates the concept of geologic time, and helps the learner understand why fossils are rare.

This resource provides graphics, as well as explanation, of the remains of Homo habilis.

This illustration from Evolution by Monroe W. Strickberger shows the remarkable similarities between the bones in the forelimbs of various tetrapods, all of whose limbs serve very different functions.

Read a description of Homo sapiens as a species, learn about the variety of Homo sapiens fossils that have been found, and discover evidence of the culture of these early people.
