Adaptation and Environmental Pressures: How Life Responds to Change
Discover how organisms develop structural, behavioral, and physiological adaptations in response to environmental pressures through the powerful mechanism of natural selection.
What You'll Learn
Adaptations are inherited traits shaped by natural selection over generations.
Three adaptation types are structural, behavioral, and physiological traits.
Environmental pressures like predation and climate drive natural selection forward.
Genetic variation provides different traits for natural selection to act upon.
What You'll Practice
1
Students identify structural, behavioral, and physiological adaptations with examples.
2
Questions explore how environmental pressures drive natural selection in populations.
3
Learners analyze real animal adaptations like camouflage, mimicry, and food caching.
Why This Matters
Understanding how environmental pressures drive adaptation helps students explain biodiversity, predict species responses to climate change, and appreciate the mechanisms that sustain life on Earth.
