| A | B |
|---|
| Evidence of Evolution | fossils, comparative anatomy, comparative embryology, comparative biochemistry |
| Fossils | traces of once living found in sedimentary rock |
| Age of fossils | determined by radioactive isotopes |
| Half-life | time required for 1/2 of radioactive molecules to decay |
| Over time, organisms of ___ ___ appeared on earth | increasing complexity |
| Homologous Structures | things that have the same structure and origin |
| Vestigial Organs | organs that seem to serve no useful function |
| Embryology | comparing stages of embryonic development |
| Common Ancestry | If species change over time, there should be examples of living species that may have come from a common ancestor |
| Jean Baptiste Lamarck | "Inheritance of acquired characteristics" |
| Charles Darwin | Current Theory of Evolution - Natural Selection |
| Natural Selection | Individuals with advantageous variation are more likely to survive and reproduce. Favorable genetic traits accumulate in a population over generations. |
| Adaptive Radiation | many related species evolved from a single ancestor |
| Mutation | changes in the genetic make up of an organism |
| Artificial Selection | mates are selected by humans |
| Carrying Capacity | The limit of an organism that an area can support |
| Continental Drift | Land mass shift that happened over time |
| Extinction | When all of a species has died |
| Fossilization | The process by which organisms are preserved |
| Galapagos | Place where Darwin's observations led to his theory on evolution |
| Geographic Isolation | When populations do not come into contact with each other due to where they live |
| HMS Beagle | Name of the ship Darwin sailed on |
| Mass Extinction | When a huge number of species die off in a short period of time. |
| Migration | Movement of individuals into or out of a population |
| Origin of the Species | Darwin's book about evolution |
| Pangaea | Name of the lone land mass when there was only 1 continent |
| Speciation | Process by which a new species develops |
| Invertebrates | Animals that do not have a backbone |
| Peppered Moth | Example of how pollution in England caused changes to the organisms that live there |
| Survival of the Fittest | Term used to describe Darwin's theory that means Natural Selection |
| Population | The total number of a type of organism at some location |
