12001200522 | Natural Selection | A process in which individuals that have certain inherited traits tend to survive and reproduce at higher rates than other individuals because of those traits. | 0 | |
12001200523 | Major points of The Origin of Species | Evolutionary change is based on the interactions between populations and their environment which results in adaptations (inherited characteristics) to increase fitness. 1. Adaptations 2. Overproduction | 1 | |
12001200524 | Evolution | Change over time in the genetic composition of a population. | 2 | |
12001200525 | Evolutionary Adaptations | A genotype of inherited traits that enhance an individuals ability to survive and reproduce in a particular movement. | 3 | |
12001200526 | Taxonomy | The scientific study of how living things are classified. Created by Linnaeus. | 4 | |
12001200527 | Aristotle | Life forms arranged by complexity. Believed in Creationism and Natural Theology. | 5 | |
12001200528 | Natural Theology | theology or knowledge of God based on observed facts and experience apart from divine revelation. Studying nature | 6 | |
12001200529 | Linnaeus | founder of taxonomy; binomial nomenclature | 7 | |
12001200530 | Cuvier | Paleontologist; look into strata; believed in catastrophism. | 8 | |
12001200531 | Catastrophism | Catastrophe destroyed many living species then immigrant species repopulated | 9 | |
12001200532 | Hutton | Gradualism. earth is millions of years old, major changes are caused by small changes over time. Continuous process. | 10 | |
12001200533 | Lyell | Uniformitarianism; Earth processes same rate since the past. Earth is old. | 11 | |
12001200534 | Lamarck | Published Theory of Evolution in 1809. 1. Told of Inheritance of Acquired Strengths. 2. Use and Disuse | 12 | |
12001200535 | Malthus | Economist; More babies are born than deaths. | 13 | |
12001200536 | Charles Darwin | Origin of Species. Descent with modification. | 14 | |
12001200537 | Voyage of the Beagle | 1831 trip around the world- mainly Galapagos Islands. | 15 | |
12001200538 | Alfred Wallace | Published his own theory of evolution by natural selection about the same time as Charles Darwin | 16 | |
12001200539 | Artificial Selection | Breeding organisms with specific traits in order to produce offspring with identical traits. | 17 | |
12001200540 | Darwin's Mechanisms of Evolution | Descent with Modification | 18 | |
12001200541 | Homologous Structures | Have similar structures from common ancestors, but serve different functions. Ex: human arm, bat wing | 19 | |
12001200542 | Vestigial Structures | A structure that is present in an organism but no longer serves its original purpose | 20 | |
12001200543 | Analogous Structures | similarities among unrelated species that result from convergent evolution. Ex: Wings for flying | 21 | |
12001200544 | Molecular homologies | similar molecular composition of proteins, DNA | 22 | |
12001200545 | convergent evolution | Process by which unrelated organisms independently evolve similarities when adapting to similar environments. | 23 | |
12001200546 | Biogeography | study of the distribution of organisms around the world | 24 | |
12001200547 | Endemic Species | Species that are native to and found only within a limited geographic area. | 25 | |
12001200548 | embryonic homologies | Comparison of early stages of animal development reveals many anatomical homologies in embryos that are not visible in adult organisms | 26 |
