| Term | Definition |
|---|---|
| Evolution | The process of change in inherited traits of populations over generations, resulting in the diversity of life. |
| Natural Selection | the process where organisms with traits better suited to their environment are more likely to survive, reproduce, and pass those advantageous traits to their offspring. |
| Charles Darwin | An English naturalist who developed the theory of evolution by natural selection |
| Adaptation | A characteristic or behavior of a living thing that helps it survive and reproduce in its environment. |
| Population | A group of individuals of the same species living in the same area and capable of interbreeding. |
| Homologous Structure | body parts in different species that have a similar underlying structure and common evolutionary origin, even though they may have different functions |
| Vestigial Structure | a body part or organ that has lost its original function through evolution. |
| Divergent Evolution | the process where two or more species with a common ancestor gradually become more different over time, leading to the formation of new species. |
| Convergent Evolution | the process where unrelated species independently develop similar traits, often due to adapting to similar environments or ecological niches. |
| Analogous Structure | A body part in different species that serves a similar function but has evolved independently, rather than from a common ancestor. |
| Embryology | The branch of biology that studies the development of embryos from fertilization through the fetal stage. |
| Inherited | Traits or characteristics passed down from parents to offspring through the transmission of genetic material, such as DNA. |
| Acquired Traits | A characteristic developed during an organism's lifetime due to environmental factors or experiences, not from genetics. |
| Artificial Selection | when humans intentionally breed organisms with desirable traits to produce offspring with those same traits. |
| Mutation | A change in an organism's genetic material (DNA). |
