Theory of Evolution.
| Question | Answer |
|---|---|
| What is evolution? | Change over time. |
| What was Charles Darwin's contribution to science? | Darwin developed a theory of evolution tat explains how modern organisms evolved over long periods of time from common ancestors. |
| What did Darwin notice about biodiversity around the world? | Places around the world that had similar habitats often had different animals that were ecologically similar |
| What is fossil? | the preserved remains or traces of ancient organisms. |
| What did Darwin notice about biodiversity within a local area? | Darwin noticed that different, related species often lived in different habitats within a local area. |
| What did Darwin notice when he compared some fossils to living species? | Darwin noticed that some fossils of extinct animals were similar to living species. |
| How did Jean-Baptiste Lamarck propose that species evolve? | Lamarck suggested that indiviual organisms could change during their lifetimes by using or not using parts of their bodies. |
| How did James Hutton and Charles Lyell conclude about Earth's history? | Hutton and Lyell concluded that Earth is extremely old. |
| What was Thomas Malthus's view of population growth? | Malthus reasoned that if the human population were to grow without control, then there would not be enough space and food for everyone to live. |
| What is artificial selection? | The selective breeding of plants and animals to promote desirable traits in offspring. |
| How is variation used in artificial selection? | In artificial selection, nature provides the variations, and humans select traits they find useful. |
| What is adaptation? | A heritable characteristic that increases an organism's ability to survive and reproduce in its environment. |
| What is fitness? | How well an organism can survive and reproduce in its environment |
| What is natural selection? | The process by which organisms that are most suited to their environment survive and reproduce most successfully |
| What is natural selection also called? | Survival of the fittest. |
| When does natural selection occur? | Natural selection occurs when more individuals are born than can survive. |
| How does common descent explain the connection between living and extinct species? | According to the principle of common descent, all species (living and extinct) are descended from ancient common ancestors |
| What is biogeography? | The study of past and present distribution of organisms. |
| How does the geographic distribution of species today relate to their evolutionary history? | Patterns linking adaptations to environments around the world provide evidence for natural selection |
| What is homologous structures? | Structures that are similar in different species of common ancestry. |
| What do homologous structures suggest about the process of evolutionary change? | Evolutionary theory explains that homologous structures adapted to different purposes are the result of descent with modification from an ancestor. |
| What analogous structures? | structures that are similar in function but not in structure; they do not suggest common ancestry. |
| What are vestigial structure? | A structure that is reduced in size and has little or no function. |
| What do similarities in embryonic development suggest about the process of evolutionary change? | Similar patterns of embryo development provide evidence that organisms have descended from a common ancestor. |
