What is evolution?
Content is AI-assisted and continuously improved through educator review
Learning Objective
Students will define and understand evolution through guided practice and application.
Welcome to Evolution and Natural Selection! In this lesson, we'll explore what is evolution?. Scientific inquiry allows us to investigate and explain natural phenomena.
Evolution is change in species over time. Natural selection, discovered by Charles Darwin, explains how evolution works. Process: 1) Variation: individuals have different traits (some due to mutations). 2) Competition: more organisms are born than can survive. 3) Selection: individuals with helpful traits survive and reproduce more. 4) Adaptation: helpful traits become more common over generations. Example: faster rabbits escape predators, survive, and pass on "fast" genes. Over time, the population evolves. Natural selection explains life's diversity and adaptation!
As you work through today's material, pay attention to the examples and try to identify the patterns or strategies being used. This will help you apply these concepts to new problems.
Take notes on key points and make connections to what you've already learned in previous lessons.
