evolution

3. a random fluctuation in the frequencies of different gene versions (alleles) within a population, particularly in small or isolated populations
4. a process where humans intentionally choose parent organisms with desirable traits to reproduce and pass on those traits to future generations
5. internal, functional changes in an organism's body that help it survive and reproduce in a specific environment
7. the phenomenon where some individuals within a population leave more offspring than others, due to variations in their traits, which can influence their survival and reproductive success
9. the seasonal or regular movement of animals, typically from one habitat to another, in search of better conditions for reproduction, food, or other resources
10. a change in the DNA sequence of a cell
12. a natural adaptation where organisms, including animals and plants, blend into their surroundings to hide from predators or prey, or to deceive them
14. the physical characteristics of an organism that enhance its survival and reproduction within its environment
15. anatomical features or structures that were fully functional in ancestral organisms but have lost most or all of their original function in the descendant species

1. the process by which different kinds of living organisms are thought to have developed and diversified
2. similar features in different species that serve the same function but have different evolutionary origins and underlying structures
6. an organism's ability to survive and reproduce in its environment
8. when one organism, the mimic, evolves to resemble another organism or environmental feature, the model, to gain an advantage, often protection from predators or other selective pressure
11. refers to the heritable traits (physical, behavioral, or physiological) that enhance an organism's ability to survive and reproduce in a specific environment
13. the process by which organisms better adapted to their environment tend to survive and reproduce more successfully
