Evolution
| Term | Definition |
|---|---|
| Evolution | Evolution is the process of change in living organisms over time through genetic modification, resulting in the development of new species from common ancestors |
| Natural selection | Natural selection is the process by which organisms with traits better suited to their environment survive and reproduce more successfully, passing those advantageous traits to their offspring |
| Charles Darwin | Whose theory of evolution by natural selection |
| Adaptation | the process of adjusting to new conditions, the modification of an organism through natural selection, and the creation of a new work based on an existing one |
| Population | the total number of people living in a specific country, region, or the world |
| Homologous structure | similar anatomical features in different species that have a common origin but may have evolved to have different functions |
| Vestigial structure | a physical feature or behavior that has lost its original function through evolution but remains in an organism as a remnant of an ancestral trait |
| Divergent Evolution | the process where closely related species or populations accumulate differences, leading to the formation of new species from a common ancestor |
| Convergent Evolution | the process where unrelated organisms independently evolve similar traits because they adapt to similar environments or ecological niches |
| Analogous Structure | body parts in different species that have similar functions but evolved independently, without a common ancestor |
| Embryology | the scientific study of the formation and development of an embryo and fetus from fertilization until birth |
| Inherited | to receive something from a predecessor, whether it's property, a quality, or a genetic trait passed down from parents |
| Acquired Traits | characteristics that an organism develops during its lifetime, rather than being born with them |
| Artificial Selection | the process where humans intentionally choose plants and animals with desirable traits to reproduce and pass those traits to offspring |
| Mutation | a change in the DNA sequence of a cell, which can occur spontaneously or be caused by environmental factors like chemicals or radiation |
