EVOLUTION

3. preserved remains or traces of ancient organisms.
5. Describes how well an organism can survive and reproduce in its environment.
6. this person argued that laws of nature are constant over time.
7. This person reasoned that if the human population grew unchecked, there wouldn't be enough living space and food for everyone.
8. Any heritable characteristic that increases an organism's ability to survive and reproduce in its environment.
11. nature provides the inherited variations, and humans select those variants they find useful.
12. Change overtime; the process by which modern organisms have descended from ancient organisms.
13. Similar structures, like the bones of vertebrate limbs, that are shared by related species and have been inherited from a common ancestor.
14. This person suggested that individual organisms could change during their lifetime by selectively using or not using various parts of their bodies.
16. occurs in any situation in which more individuals are born than can survive, natural heritable variation affects the ability to survive and reproduce, and fitness varies among individuals.

1. inherited structures from ancestors, but have lost much of their original size and function.
2. this person recognized the connections between geological processes and features.
4. Body parts that serve similar functions, but do not share structure and development.
9. the study of where organisms live now and where they and their ancestors lived in the past.
10. Ancestral organism shared by two or more descendent lineages.
15. Developed a theory of biological evolution that offered a scientific explanation for the unity and diversity of life, by proposing how modern organisms evolved through descent from common ancestors.
