This 4 page worksheet examines three different examples of co-evolution in populations that rely directly on one another. Students are asked to pull information from text, analyze diagrams and graphs, and explain how selection pressures from competing populations can lead to shifts in allele frequency.
I have uploaded this in a .docx format, so you can modify and differentiate it to fit your classroom and students' needs. Enjoy!
HS-LS4-2 Construct an explanation based on evidence that the process of evolution primarily results from four factors: (1) the potential for a species to increase in number, (2) the heritable genetic variation of individuals in a species due to mutation and sexual reproduction, (3) competition for limited resources, and (4) the proliferation of those organisms that are better able to survive and reproduce in the environment.
HS-LS4-4 Construct an explanation based on evidence for how natural selection leads to adaptation of populations.
HS-LS4-3 Apply concepts of statistics and probability to support explanations that organisms with an advantageous heritable trait tend to increase in proportion to organisms lacking this trait.
