Nhm: Amino Acid Sequences Show Evolution
This lesson plan focuses on differences in the amino acid sequence of hemoglobin and myoglobin proteins. They use the number of differences to create a phylogenetic tree.

Ck 12: Life Science: Structural Evidence for Evolution
[Free Registration/Login may be required to access all resource tools.] Even though two different species may not look similar, they may have similar internal structures that suggest they have a common ancestor. That means both evolved...

University of California Museum of Paleontology: Similarities and Differences
A module explaining how two different organisms can possess similar traits by sharing a common ancestor(homology) or due to convergent evolution(analogy).

University of California Museum of Paleontology: Homologies
These pages are from the Understanding Evolution website for teachers. They focus on homologous structures that organisms with common ancestors share.

Understanding Evolution: An Introduction to Evolution
A textbook definition along with an explanation of the scientific theory of evolution.
Northern Arizona University
Northern Arizona University: Embryos and Evolution
In this lesson, students study the embryos of different organisms at three stages of development to look for features that suggest a common ancestry.

Alex: Why Comparative Embryology Matters in the Real World
In this lesson, students compare similarities in the embryos of different organisms to look for features that would indicate common ancestry. They will then investigate how understanding this aspect of evolution has real-world...

Pbs News Hour Extra: Scientists Discover Oldest Human Ancestor
Scientists have recently published their research into fossil bones from Ethiopia that they say came from an ancestor common to both humans and chimpanzees. They have named the ancestor Ardipithecus ramidus. In the articles and video,...

Access Excellence: Molecular Biology/primate Phylogeny
This lesson plan involves comparison of amino acids to create a phylogenetic tree of primates. Students will also use other species information to draw conclusions about evolutionary relationships.

Nhm: Restriction Maps to Cladograms Lesson
This lesson plan requires students to analyze DNA restriction maps to determine the differences in the sequence for several primates and humans. They then use the information to create a cladogram.

Biology Wise: Examples of Analogous Structures
Explains that analogous structures are ones that are similar in different organisms yet have no common ancestry. This type of phenomenon occurs with convergent evolution. Includes lots of examples for both animals and plants.

Wonderville: Charles Darwin
Charles Darwin was born in England on February 12, 1809. He was a "naturalist," best known for his theories of evolution. Darwin collected evidence that all life on Earth "evolved" from a common ancestry. He studied the process of...
