Evolution
7th Grade Science Evolution~PearsonSucess
| Question | Answer |
|---|---|
| Aristotle classifyed by thoses that can..... | swim,fly and walk/crawl/run |
| Who recorded each species appearance,movement and behavior? | Aristotle |
| Who believed that species are more closely related based on observable features? | Linnaeus |
| Who invented Binomial Nomenclature? | Linnaeus |
| What is a group that can mate and produce fertile offspring? | Species |
| A Genus is..... | a group of similar, closely, related organisms |
| Who thought that species with similar evolutionary histories are classifyed more closely together? | Darwin |
| What is the process by which a species changes, gradually based on it's enviroment? | Evolution |
| Who wrote "Philosophic Zoologigue: Therory of Inheirited Acquired Characteristic"? | Lamarck |
| Who's ideas were highly disaproved? | Lamarck |
| Lamarck believed in a __________ therory... | use/disuse |
| Who thought that changes occur within a lifetime are passed to offspring? | Lamarck |
| How is Binomial Nomenclature formatted? | Genus,species (underlined or itailizized) |
| Wallace wrote......? | "The Malay Archipelago" |
| Who was the first to concieve the idea of evolution through natural selection? | Wallace |
| Darwin wrote.....? | "On the Origin Species" |
| Who officialy established/ originated the theorory of evolution? | Darwin |
| What ship did Darwin ride on? | HMS Beagle |
| Which islands did Darwin visit? | Galapogos |
| Darwin is best known for studying.....? | Finches |
| What is the fact that some variations gradually accumulate while other variations disapear? | Selection |
| What is adaptattion (add-dap-tay-shun)? ;) | a trait that helps an oganism survive and reproduce |
| What is one example of adaptation? | *answers may vary* .the trait of beak shape. |
| What is an example of natural selection? | *answers may vary* .different beak shapes. |
| The process by which individuals that are better adapted to their enviromentare more likely to survive and reproduce, than other members of the same species? | Natural Selection |
| Dog breeding is an example of...? | Artificial selection |
| In artificial selection who chooses which traits will be passed on? | Humans |
| Far more turtles are born than will survive is an example of....? | Overproduction |
| The struggle for limited resources is...? | Competition |
| A turtle not finding enough food or shelter oooorrrr suffer to predation is an example of....? | Competition |
| Some turtles are born with the ability to swim faster away from predation. This is a differance between cells of individuals of the same species. What is the term for this situation? | Variation |
| The ability to reproduce offspring who can also reproduce desirable/fertile offspring: ex. survivng turtle live long enough to reproduce and pass genes. This is an example of....? | Biological Fitness |
| What is the process in which new genetically different species evovle from the rest of the main/original populaation? | Speciation or Population Bottleneck |
| What is the definition and an example for Geographic Isolation? | The seperation of 2 population of the same species or breeding group by a physical barrier: ie... land, water, habitait or volcano. An example of this is the different types of African Elephants... western is different than central, eastern and southern. |
| What is it called when organisms are seperated by behavioral, physical or genetic differances... you seperate yourself.(ex:birds of the same species in different habitaits decorate nests with different material to attract mates.....? | Reproductive Isolation |
| Blank is when changes occur in genetics due to chance (not natural selection.... probability)? | Random Genetic Drift |
| What is an example of a Random Genetic Drift? | *Ansers will vary* "smalll beetles are generally weaker and should die off, but live donto random situations......." |
| What do scientists use to track the evolutionary history of species? | A Branching Tree |
| What are the four types of evidence that scientists use to determine relationships among greoups? | Anatomical (body Structure) Embryonic (early) Development DNA Fossil Record |
| What is Anatomical(Body Structure)? | Comparing the struture of living things |
| What is a homologous structure? | Body structure that are structually similar in related species;provide evidence that the structures were inheireted from a COMMON ANCESTOR!!! |
| What type of evidence compares stages of developement BEFORE birth? | Embryonic (Early) Developement ~Having similar structures in early development suggest relationship and a common ancestor |
| How is DNA evidence used? | ~Compares the chemiccal makeup of living AND extinct organisms... (DNA, RNA, Nucleic Acids (Make DNA) Amino Acids (Make Proteins)) |
| What does fossil record compare? | The structure and chemical makeup of EXTINCT organisms. |
| What is punctuated equilibria? | A hypothesis that evolutionary development is marked by isolated episodes of rapid speciation between long periods of little or no change. |
| What is the policy of gradual reform rather than sudden change or revolution called? | Gradualism (slow and stedy) ~Darwin believed in this |
| What type of dating iss it when two fossils are being compared in order to find which is older? | Relative Dating |
| What is absolute dating? | Absolute dating is when scientists use the speed of radio active decay of elements to predict the actual age of an individual fossil. |
| What is the order of the levels of classifacation? | Kingdom Phylum Class Order Family Genus Species (7 levels) ~Keeping Precious Creatures Organized For Grumpy Scientists |
| Who's theory of evolution LED TO Darwin's Therory of evolution? | Wallace |
| Who's therory of ACQUIRED characteristics was criticized and disapproved? | Lamarck |
| What is the process of grouping things based on their similarities? | Classification |
| Genus isss... | A classifacation grouping that consists of a number of similar, closely related species |
| What is a taxonomic key? | A series of paired statments that describe the physical chracteristics of different organisms |
| When a variation makes an organism better able to survive and reproduce, then this variation gradually accumulates while other variations disappear, what is this term called? | Selection |
| The process by which organisms that are better suited to their enviroment are more likely to survive and reproduce than other members of the same species is..... | Natural Selection |
