Question | Answer |
Evolution is…. | ability of organism or population to change slowly over time. |
A species can…. | mate and produce fertile offspring |
Adaptation is…. | a characteristic that helps an organism survive and reproduce (happens over a short time) |
Fossils….. | remains or imprints organisms preserved in layers of rock |
Fossil record | timeline of life provided by remains of dead organisms |
Sediment/sedimentary rock | where fossils are likely to be found |
Father of evolution is…. | Charles Darwin |
Types of bird Darwin examined and compared. | Finches |
What characteristic did Darwin compare with the finches? | the shapes of their beaks |
What was limited in his theory on evolution/natural selection because he didn't know about... | genetics/differences in genes create variation |
A trait is…. | an inherited characteristic |
Natural selection….. | lets individuals with the better traits survive and reproduce more successfully |
Four parts of natural selection | overproduction - inherited variation - struggle to survive - successful reproduction |
When spider produces hundreds of eggs and only few survive; this is... | over production |
When organism's offspring are not identical - that is... | inherited variation |
Groups of individuals of same species living in same place... | population |
Populations are limited by... | starvation, disease, competition and predation |
Why do insects adapt quickly to insecticides? | there generation time is short |
When two isolated groups become isolated and start adapting to new environment - this begins | speciation |
Parts of speciation | separation - adaptation - division |
When speciation does occur - what is a result | The two groups cannot interbreed anymore |
If a farmer want to produce vegetables that will grow in a specific climate... | selective breeding |
If two organisms have similar traits and DNA…. | probably share a common ancestor |
