Evolution & Ecology+50 
Evolution & Ecology are interconnected scientific fields. Evolution studies how species change over time through genetic variation and natural selection, leading to adaptation and the emergence of new species. Ecology examines how organisms interact with each other and their environment, shaping communities and ecosystems. Together, these disciplines explain the diversity of life on Earth, how organisms adapt to their environments, and how environmental changes influence evolutionary processes and ecological relationships.

💡 Key Takeaways
- Explain how genetic variation and natural selection drive evolution and adaptation.
- Describe how evolution can lead to the emergence of new species (speciation).
- Understand how organisms interact with each other and their environment (predation, competition, symbiosis) to shape populations and communities.
- Explain how ecosystems organize energy flow and nutrient cycles (food webs, trophic levels) to influence biodiversity.
❓ Frequently Asked Questions
What is evolution?
Evolution is the change in the genetic makeup of a population over generations, driven by variation, natural selection, mutation, gene flow, and genetic drift.
How does natural selection lead to adaptation?
Natural selection favors individuals with traits that improve survival or reproduction, increasing those traits in the population over time and resulting in adaptation.
What is ecology?
Ecology studies how organisms interact with each other and their environment, including relationships, energy flow, and how communities and ecosystems are formed.
How are evolution and ecology connected?
Evolutionary processes act on populations within ecological contexts; ecological interactions and environments create selective pressures that shape evolutionary changes.
