Z's Evolution
Theory of evolution
| Question | Answer |
|---|---|
| Adaptations | Characteristics of a species that enable it to survive. |
| Behavioral adaptation | An adaptation that involves the way an organism behaves. |
| mimicry | The resemblance of one species to another species. |
| selective breeding | The breeding of organisms for desire charterstics. |
| artificial selction | the result of seletive breeding. |
| camouflage | an adaptation that enables a species to blend in with its enviroment. |
| structural adaptation | an adaptation that involves color, shape, and other physical charterstics. |
| funcitional adaptation | an adption that involves internal body system that affect biochemistry. |
| natural selection | explains how populations change as their environment changes. |
| variaitions | slight differences in the appearence of individual members of a speices. |
| geologic time scale | a chart on earths past |
| biological evlolution | changes over time |
| trace fossil | evidence of an organism activty |
| extinction | occurus when no induivduals of species remain |
| isotopes | atoms of the same element that have different numbers of nutrons |
| fossil record | all fossils ever discover on earth |
| mold | impression of an organism in rock |
| cast | fossil copy of an organsim in a rock |
| tissiue | simmilar cells that work together |
| charles darwin | devloped a theory about how speices envolved from mother speices. |
| Mineralization | is when an organism dies and can be burried in mud or sand or other sediments in a stream or river |
| Carbonization | forms when a dead organism is compresed over time and pressure drives off the orgamisms liquids and gasses |
| Molds | is the impression of an organism in a rock |
| Trace Fossils | is the preserved evidence of an organism-example foot prints |
| Comparative anatomy | is the study of similarities in differences among structures of living species |
| Analogous structure | Body part that perform a similar function but differ in structure |
| Vestigial structure | body parts that have lost their orginal through evoulution |
| Embryology | the science of the development of embryos from fertilization to birth |
| What are the four fossils are transformations? | Mineralizations, carbonization, molds & casts and trace fossil |
| what would be an example of vestigial structure? | wings on an ostrich, leg bones on pythons, and eyes on cave fish |
| cast | is a fossil copy of an organism in a rock |
| Homomlogous structures | are body parts of organisms that are similar in structure and position but different in function |
| What causes extinction? | change in enviorment, food , shelter |
| According to the fossil record how many mass extintions have occured during the Phanerozoic eon | 5 mass extinctions |
| when does a mass extinction occur? | when many species become extinct with in a few million years. |
| What is a naturalist? | A person (like Darwin) who studied plants and animals by observation. |
| Why did Darwin travel? | To look at the same kinds of species but in different enviorments. |
| What is Darwin's theory? | Organisms with variations help them survive in their own enviorment to help adapt, reproduce, live longer, and compete better. |
| Who wrote On The Origin of Species and what was it about? | Darwin wrote this book about his theory of species evolution and adaption |
| Besides the Natural Selection theory, what did Darwin learn about studing pigeons? | Selective Breeding |
| What is the geological time scale? | How scientists keep track of time millions of years ago. (History is divided into 4 eons contaning 3 era's each) |
