| Who said species don't become extinct but instead evolve into different forms in response to changes in their environment? | Lamarck |
| Who believe that more complex forms of life evolved from less complex forms? | Darwin |
| Who believed that the earth is much older than previously thought? | Buffon |
| To be considered members of the same species, organisms must be able to..... | Reproduce together and have a fertile offspring |
| What is incorrect about Lamarck's theory of how organisms evolve? | He did not explain how traits were passed on to the offspring |
| Which scientist developed a system for classifying organisms that is still used today? | Carolus Linnaeus |
| Who thought of this idea? Changes on earth occurred to by small steps over long periods of time – gradualism? | James Hutton |
| Who thought of this idea? Resources such as food, water, and shelter were natural limits to population growth? | Thomas Malthus |
| Who thought of this idea? Geologic processes add up over a long period of time to produce great change – uniformitarianism | Charles Lyell |
| What is a trace of an organism that existed in the past? | A fossil |
| What is the process of biological change by which descendants come to differ from their ancestors? | Evolution |
| What are events such as volcanoes, floods, and earthquakes called? | Catastrophism |
| What can be summarized by the phrase the present is the key to the past? | Uniformitarianism |
| Who was Charles Darwin's poetic grandfather? | E. Darwin |
| Who thought that giraffes longneck evolved from reaching high trees? | Lamarck |
| Who groups living organisms into categories based on what they look like? | Linnaeus |
| Who wrote history natural in 1749? | Buffon |
| What is a variation among members of different species called? | Interspecific variation |
| What is variation among members of the same species called? | Intraspecific variation |
| What island chain in South America was the source of many of Darwins insights? | Galapagos islands |
| Dharmasala populations of various species that seemed well suited to their environment. What did this suggest? | That species might be able to adapt to their surroundings overtime |
| True or false? Darwin theorized that the fossils of huge animals such as Glyptodon, a giant armadillo, which looks similar to armadillos in Darwins time, showed that living species were related to one another once. | True |
| True or false? Darwins discovery of marine organisms high in the mountains led him to think that ancient people have carried sea animals from the seaside up into the mountains. | False |
| True or false? Darwin thought the earth must be much older than scientist previously thought. | True |
| True or false? If earth was much older than previously thought, darwin knew there had been time for species to evolve gradually. | True |
| Adaptation or variation? Differences in the physical traits of an individual from those of other individuals in the group to which it belongs. | Variation |
| Adaptation or variation? A feature that allows an organism to better survive in its environment. | Adaptation |
| Adaptation or variation a tortoise population lives in an area with high grass. These tortoises have longer necks then tortoises that live in other areas. | Adaptation |
| Adaptation or variation? One bird in a population has a slightly thicker beak then it's relatives. | Variation |
| Why did artificial selection interest Darwin? | He had noticed that humans could breed for certain characteristics and animals |
| Why must a selected trait be heritable? | If I selected trait is not heritable, it cannot be passed down to the next generation |
| In natural selection, what must be true of traits that are passed down through generations? | The traits must be one that gives an advantage to certain individuals |
| What important idea from Thomas Malthus inspired Darwin? | Disease and a limited food supply keep the population smaller |
| What is producing many offspring, some that may not survive? | Overproduction |
| What are individual differences that may be heritable? | Variation |
| What is a certain variation well-suited for the environment? | Adaptation |
| What is a heritable trait becoming common in a population? | Descent with modification |
| What is this an example of? Large teeth and jaws become more common in jaguars because there heritable characteristics. | Descent with modification |
| What is this an example of? Jaguars with large teeth and jaw's survive longer because they can eat shelled the reptiles. | Adaptation |
| What is this an example of? By chance, some jaguars are born with slightly larger teeth and jaw's. | Variation |
| What is this an example of? A jaguar or may produce many offspring, but because of competition, not all of them will survive long enough to reproduce. | Overproduction |
| Humans are the selective agent in.... | Artificial selection |
| The environment is the selective agent in.... | Natural selection |
| The ability of a trait to be passed down from one generation to the next is called..... | Heritability |
| ______ Selection occurs when humans deliberately breed for certain characteristic | Artificial |
| ______ Selection occurs when individuals with beneficial Traits produce more surviving offspring than other individuals of the same species. | Natural |
| What type of evidence describes the example? Species in one area may match species in another area that is separate but still nearby. | Geography |
| What type of evidence describes the example? Two different species may have larvae that are very similar. | Embryology |
| What type of evidence describes the example? The body parts of different species may have homologous structures. | Anatomy |
| Pelvic bones in snakes are in example of: | vestigial structures |
| What conclusion can you draw from the fact that many modern whale species have vestigial pelvic and leg bones? | The ancestors of whales may have been land mammals |
| Feature that is similar in structure in different organisms but has different functions is an example of: | Homologous structures |
| Feature that performs a similar function in different organisms but not similar in origin is an example of: | Analogous structures |
| Feature that is not evidence of a common ancestor is an example of: | Analogous structures |
| Remains of an organ or structure that had a function in an early ancestor is an example of: | Vestigial structure |
| What is the wing of a bat and the hand of a human an example of? | Homologous structures |
| What is the wing of a bird in the wing of an insect an example of? | Analogous structures |
| Which concept is this evolutionary theory describing? The more related organisms are, the more similar their DNA will be. | DNA sequence analysis |
| Which concept is this evolutionary theory describing? The basis of molecular fingerprinting, which compares proteins among cell types. | Proteins comparisons |
| What is the study of the distribution of organisms around the world? | Biogeography |
| what is adaptation | the feature that allows an organism to better survive in environment |
| what is artificial selection | process which humans change a species by breeding it for a certain trait |
| what is decent with modification | a heritable trait becoming common in a population |
| what is natural selection | mechanism by which individuals that have inherited beneficial adaptions show differentials reproduction success |
| who is being referred to when you see "acquired characteristics" for example is you are really toned, then your child will be as well | Lamarck |
