Natural Selection

1. A phrase that describes the principle of natural selection, where the organisms best suited to their environment are more likely to survive and reproduce.
7. A trait or characteristic that enhances an organism's ability to survive and reproduce in its environment, resulting from the process of evolution.
8. An English naturalist and biologist known for developing the theory of evolution through natural selection. His work laid the foundation for modern evolutionary biology.
9. Actions or behaviors of an organism that help it survive in its environment, such as migration patterns or feeding habits.
10. The gradual development of species over time through changes in their genetic traits. This process can lead to the emergence of new species.

2. Physical features of an organism that enhance its survival and reproduction, such as the shape of a beak or the color of fur.
3. A group of organisms that can interbreed and produce fertile offspring. Members of the same species share common characteristics.
4. The process by which organisms better adapted to their environment tend to survive and produce more offspring. This mechanism drives evolution.
5. Differences in DNA among individuals, which can lead to variations in traits. This variation is essential for natural selection to occur.
6. Internal body processes that enhance an organism's ability to survive, including changes in metabolism or temperature regulation.
