|---|---|---|---|---|---|
| Charles Darwin: Who was he and what did he do? | A scientist who came up with the idea of evolution by natural selection
🗑
|
||||
| Adaptations + Examples | The tortoises and finches were noticibly different on different islands. They had different shells and beaks depending on the environment
🗑
|
||||
| Evolution + examples | Darwin thought that species gradually changed over time like giraffe necks. It makes the species better adapted to new conditions
🗑
|
||||
| Natural selection + examples | Makes certain individuals better adapted to their environment like finches from a rain forest versus a forest
🗑
|
||||
| Overproduction + examples | Most species produce far more offspring than can possibly survive like lions
🗑
|
||||
| Competition + examples | Since food and other resources are very limited the offspring has to compete to get food
🗑
|
||||
| Variations + examples | Indivdual members of a species differ from one another in their individual traits. For example some turtles will swim faster than others.
🗑
|
||||
| Survival of the fittest | Some variations allow individuals in a species to survive more easily than others. For example "fast swimming" turtles will survive more easily when first hatched than the slower swimming turtles
🗑
|
||||
| How a new species forms | When a group of individuals remains separated from the rest of the group long enough to evolve different traits to survive in a different environment
🗑
|
||||
| Fossils as evidence | Scientists use many different methods other than DNA to prove evolution , fossils as clues for evolution
🗑
|
||||
| Homologous structures + examples | similar bone structure are evidence to a common ancestor, similar structures in organisms but used for different purpose depending on the environment they are in . Suggests a common ancestor
🗑
|
||||
| Similarities in embryos | common ancestors
🗑
|
||||
| Similarities in DNA | species inherits genes from common ancestor
🗑
|
||||
| Branching trees | a diagram that shows how scientist think different groups of organisms are related
🗑
|
||||
| Explain what happened in Bird Buffet in terms of Darwin's theory and Darwin's finches | nspired by observations of finches on the Galapagos Islands, Charles Darwin came up with an idea that is perhaps the most influential idea in all of science - natural selection.
