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...

Structures That Reveal Common Ancestry
Float like a butterfly, sting like a bee, check out wing shapes for common ancestry! Beginning biologists compare wings as analogous structures and discover that environment influences evolution of adaptations. A third activity relies on...

Introduction to Adaptation
Tenth graders observe collections of specimens and discuss their answers to provided questions. They explore common ancestry, homology, analogy, adaptive radiation, and evolution, while formulating creative answers based on their...

Using Amino Acid Sequences to Show Evolutionary Relationships
Compare protein fragments, count amino acids, and use the information to explore common ancestry. The resource mentions a student worksheet, however, a separate printable worksheet is not provided. The exercises are written into the...

Evidence of Evolution by Natural Selection - Testable Hypotheses
The factors that affect selection and evolution are investigated here. Information about some common ancestry examples are given but with no real scientific evidence. This presentation is very obvious in making biased claims about...

What Can Pseudogenes Tell Us About Common Ancestry?
Students compare/constrast DNA sequence data for a portion of the rat GULO gene to the corresponding sequence in the inactive GULO gene in humans, chimpanzees, orangutans, and crab-eating macaques by identifying the shared sequences in...
