grade 7 evolution test questions

📚 Quick Study Guide

• 🌍 Evolution: The process of change in the inherited characteristics of biological populations over successive generations.
• 🧬 Natural Selection: The mechanism of evolution where organisms better adapted to their environment tend to survive and reproduce more successfully. This is often summarized as 'survival of the fittest'.
• 🌱 Adaptation: A trait that helps an organism survive and reproduce in its environment. Examples include camouflage, mimicry, and specialized structures.
• 🕰️ Fossils: Preserved remains or traces of ancient organisms. They provide evidence of past life and evolutionary changes.
• 🤝 Common Ancestry: The concept that all living organisms share a common ancestor and have diverged over time through evolution.
• 🧪 Evidence for Evolution: Includes fossil records, comparative anatomy (homologous structures), embryology, and molecular biology (DNA).
• 💡 Key Figures: Charles Darwin (known for his theory of evolution by natural selection) and Alfred Russel Wallace (independently conceived the theory of natural selection).
