- Classroom activity
Time: 50 minutes
In this reading-, writing-, and discussion-based activity, students learn about how changes in the environment can influence the phenotype of organisms. More specifically, students will be investigating the concept of a mismatch disease and how it relates to many present human phenotypes that are no longer beneficial.
- [Evidence of evolution: Grades 9-12] There is a fit between organisms and their environments, though not always a perfect fit. (LS4.C)
- [Evidence of evolution: Grades 9-12] There is a fit between the form of a trait and its function, though not always a perfect fit.
- [Mechanisms of evolution: Grades 9-12] Depending on environmental conditions, inherited characteristics may be advantageous, neutral, or detrimental.
- [Nature of science: Grades 9-12] Scientific knowledge is open to question and revision as we come up with new ideas and discover new evidence. (P4, P6, NOS3)
- [Nature of science: Grades 9-12] A hallmark of science is exposing ideas to testing. (P3, P4, P6, P7)
- [Nature of science: Grades 9-12] Scientists can test ideas about events and processes long past, very distant, and not directly observable.
- [Studying evolution: Grades 9-12] Our knowledge of the evolution of living things is always being refined as we gather more evidence.
- [Studying evolution: Grades 9-12] As with other scientific disciplines, evolutionary biology has applications that factor into everyday life.
