| Term | Definition |
|---|
| evolution | Genetically based changes in the appearance, function and or behavior of organisms through successive generations. |
| deoxyribonucleic acid | DNA in long form |
| DNA | The genetic material that serves as a "recipe" for materials, cells, organisms |
| genes | Regions along a strand of DNA which serve as recipes for the synthesis of products. |
| mutation | A change in the DNA of an individual, which most commonly arise from mistakes made during the replication of DNA. |
| mutagen | A chemical or form of radiation that can cause a mutation. E.g. mercury or UV radiation. |
| beneficial | Three basic types of mutation: ________, neutral, harmful. |
| neutral | Three basic types of mutation: beneficial, ________, harmful. |
| harmful | Three basic types of mutation: beneficial, neutral, ________. |
| harmful | Most common type of mutation. |
| mistakes made during replication | Most common cause of mutation |
| heritable | A mutation or trait that occurs within a sex cell, which can be passed to offspring and spread into a population |
| reproductive rate | What determines how fast a mutation will spread through a population |
| natural selection | Survival of the fittest. Organisms that are best suited for their particular lifestyle will be more likely to produce more offspring. Mechanism behind Charles Darwin's theory. |
| selective pressures | The primary driving forces behind natural selection are environmental change (abiotic?), and co-evolution of other organisms (biotic) within a community |
| environmental change | Two main selective pressures: __________ and co-evolution. |
| co-evolution | Two main selective pressures: environmental change and __________. |
| become extinct | Three responses to selective pressures: adapt, move, _______ |
| move | Three responses to selective pressures: adapt, _______, become extinct |
| adapt | Three responses to selective pressures: _______, move, become extinct |
| biological | Five types of extinction: _______, local, ecological, mass, background. |
| local | Five types of extinction: _______, biological, ecological, mass, background. |
| ecological | Five types of extinction: biological, _______, mass, background, local, |
| mass | Five types of extinction: biological, background, local, ecological, _______. |
| background | Five types of extinction: biological, mass, local, ecological, _______. |
| biological | Type of extinction where a species is no longer found anywhere on earth |
| local | Type of extinction which occurs when a species is no longer around in an area that it once inhabited, but can still be found in other areas |
| ecological | Type of extinction when there are so few members of a species left that it can no longer play its "role" in an ecosystem where it is found. |
| mass | Type of extinction where there is a significant rise in the number of species extinctions above the background extinction rate. We are in the 6th one. |
| background | The number of species that will go biologically extinct naturally |
| 33 | Percentage of all species of plants and animals classified as vulnerable in the US |
| endangered | Classification of a species that could soon become extinct over all. |
| threatened/vulnerable | Classification of a species that is likely to become endangered in the near future. |
| habitat destruction | Five ways for extinction to occur: rapid environmental change, ________, over hunting/collecting, pollution, introduction of alien/invasive spp, |
| over hunting/collecting | Five ways for extinction to occur: ________ , habitat destruction, pollution, introduction of alien/invasive spp, rapid environmental change |
| pollution | Five ways for extinction to occur: habitat destruction, introduction of alien/invasive spp, over hunting/collecting, ________ , rapid environmental change |
| introduction of alien/invasive spp | Five ways for extinction to occur: habitat destruction, over hunting/collecting, rapid environmental change, pollution, ________, |
| rapid environmental change | Five ways for extinction to occur: habitat destruction, over hunting/collecting, pollution, introduction of alien/invasive spp, ________. |
