| Define Evolution | The gradual change in species over time. |
| Define Overproduction | A kind of organism reproduces too much that the food cycle is unbalanced. |
| What is natural selection? | The process by wich individuals are is better adapted to their environment and are more likely to survive and reproduce. |
| How does natural selection led to evolution? | Natural selection leads to evolutionary change when individuals with certain characteristics have a greater survival or reproductive rate than other individuals in a population and pass on these inheritable genetic characteristics to their offspring. |
| What are homologous structures? | Homologous structures are body structures that are similar to related species. |
| what is an example of a homologous structure? | The arm of a human, the wing of a bird or a bat, the leg of a dog and the flipper of a dolphin or whale. |
| What are 4 pieces of evidence that support the theory of evolution? | 1. The fossil record 2. Genetic commonalities 3. Common traits in embryos 4. The universal genetic code |
| What is geographic isolation? | A population of animals, plants, or other organisms that are separated from exchanging genetic material with other organisms of the same species. |
| How can a geographic isolation lead to the creation of a new species? | The organism has to adapt to their new environment and evolve. |
| What is a branching tree (in relation to the classification of organisms? | A diagram shows how scientists think different groups of organisms are related. |
| What is taxonomy? | The scientific study of how living things are classified. |
| Why do scientists organize living things into groups? | Scientists organize living things by observing their observable traits. |
| What are two parts of an organism's scientific name? | Class, Species |
