Curated OER
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...
Curated OER
Understanding Evolution: Homology and Analogy
In this understanding evolution worksheet, 9th graders define homology and analogy. Students compare and contrast similar structures in several given species.
Curated OER
Homologous Shoes
Students examine the concept of homology by observing their shoes and those of their classmates. They summarize the observations of everyone's shoes relating it to chromosomes in cells. They share their observations with the class.
Curated OER
Homology: Where Does The Evidence Lead
Students are introduced to the topic of homology. In groups, they read a case study and compare different drawings of early vertebrate emryos. They work together to answer discussion questions and label the various parts of each embryo.
Curated OER
Homology
Students investigate the concept of homology. They are particularly interested in finding information about developmental homology. Students design a new animal correcting obvious mistakes on a worksheet provided by the teacher. They...

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).
