Structural Factors in Evolution
Laboratory activities encourage evolutionary biology scholars to consider homologous structures as evidence of common ancestry. They learn how to formulate phylogenic trees and that environment influences to genetic variation. Activities...

Evidence of Evolution by Natural Selection
Walk your junior biologists through the evidence that supports evolution. The fossil record, anatomical record, and molecular record are explained and supported by colorful graphs and pictures. Extensive notes are provided for some of...
Curated OER
Evidence for Evolution
In this evidence of evolution worksheet, students review notes given by referring to the Nelson Biology text, chapter 11/13. Students read the notes and the specified pages in the text.

Evolution: Evidence From Living Organisms
By examining fossils, scientists have collected evidence that supports the theory that species changed over time. As you read this article, study this evidence and critically evaluate whether it indicates that species may have arisen by...
