Description |
| The Evolutionary Processes of Population Change | This is a lesson plan designed to explain three evolutionary processes: natural selection, genetic drift, and gene flow. The lesson plan consists of a brief review about mutations and DNA, a PowerPoint discussion about the three evolutionary processes, and a hands-on activity. The activity is designed to help the students understand how populations change over time due to different traits in individuals in a population, as well as how to identify the different evolutionary processes in a population. |
| Asthma Island | In this activity, students simulate the founder effect on Tristan Da Cunha island. The island is located in the Southern Atlantic Ocean between South America and the southern part of Africa. It is the most isolated island on earth. The island's population is is 268 people and there are now 80 families that live in the island. Students will explore genetic drift (bottleneck and founder effect) and the importance of genetic variation in a population. |
| Is Natural Selection Random? | Students will use the real-world example of Hurricane Opal wiping out the beach mouse population from Shell Island in 1995. Students will identify the environmental pressures that led to the differentiation of the Choctawhatchee beach mouse from the mainland population (St. Andrew beach mouse) as natural selection. They will examine the beach mouse population on this island immediately following the hurricane as an example of genetic drift, and the re-population of the island as gene flow. Students will then track changes in the population from the initial re-population following the hurricane to the current population and relate this to natural selection. |
| Selection Dance Party | In this lesson, students will learn how sexual selection leads to the evolution of species by exploring how courtship rituals lead to the selection of traits in a population. |
| Evolution of a Bead Population | Students practice modeling the processes of genetic drift, gene flow, the founder effect and natural selection using a population of colored pony beads. |
| Island Biogeography | Students will study the concept of speciation and predict an island habitat"s biodiversity based on the island's size and distance from the mainland. |

| The Oldest Fish in the World Lived 500 Million Years Ago | This informational text resource is intended to support reading in the content area. The article describes the discovery of an ancient fish that provides scientists with a "missing link" in the fossil record, helping them understand when and how organisms transitioned from boneless, jawless organisms into the fish that dominate the oceans today. The text details the adaptations these ancient fish had and draws connections to adaptations found in later species. |
| New Housecat-Size Feline Species Discovered | This informational text is intended to support reading in the content area. The article discusses how scientists have discovered a species of Oncilla (little tiger cats) in Northeastern Brazil, which are a genetically different species than those in the rest of South America. |
| Remote Sheep Population Resists Genetic Drift | This informational text resource is intended to support reading in the content area. This article describes a mouflon population located on a remote island in the Indian Ocean. This population of sheep was transplanted to Haute Island over 50 years ago. Recent studies show that the population has maintained its genetic diversity. This finding challenges scientists' beliefs about the theories of genetic drift and shows the power of natural selection. |
