Jean Baptiste Lamark |
Darwin Predecessor. Proposed first evolutionary hypothesis. |
|
|
Theory of Acquired Characteristics |
Lamarck's belief that traits an individual aquires during a lifetime will be passed down genetically. |
Giraffees. |
|
Phenotype |
Physical appearance of a gene |
|
|
Naturalist? |
An expert in natural history - life science/wild life experent/natural historian |
|
|
Darwin |
Naturalist who developed the theory of evolution |
|
|
Beagle |
The ship Darwin took a five year year voyage on when he discovered evolution. |
|
|
What did Darwin orginally believe? |
That individuals and species and the world had remained unchanged since the begining of time |
|
|
Natural selection |
(1) Individual organisms withing a specisies exhibit variation. (2) These organsisms compete for means. (3) The terms of reproductive success differ from organism to organism. (4) Organims adapt to conditions as the environment changes. |
Four points |
|
Galopogos Islands |
Darwin noticed different finches had different beak size for eating different seeds. They must share a common ancestor. LIke the African Ostrich and the South American Rhea. |
|
|
Do Individuals or Populations evolve? |
Individuals |
Darwin not Lamarck |
|
Hypothesis |
Possible explanation or answer to a question that can be tested. |
|
|
Observation |
Anyu use of the senses to gather information. |
|
|
Scientific Theory |
A unifying explanation for a broad range of hypotheses and observations that have been supported by tested. It has great power to predict and explain natural phenomena. |
Theory of Gravity |
|
What are the four types of evolutionary evidence? |
(1) Anatomical Structures (2) Fossil Evidence (3) Biogeographical (4) Biochemcial |
|
|
Homogous structure |
Similar sturcutres that appear in different species that give the appearance of a shared common ancestor |
Arm bones in bats/horses/humans |
|
Vestigial structures |
Something that is fully developed in one group and has little-or no function in other. |
Pelvic bones in whales. Tail bones in humas. |
|
Analogous structuers |
Sturcutres that evolved seperately and despite appearing similarly show no sign of a common ancestor. |
Bird wings versus insect wings. |
|
Fossil |
Solidifed remains/imprints in sediment that help to establish a geological time line |
|
|
Transtional fossil |
Fossils that bear a resemblence/link to two groups in present day, classified seperately. |
|
|
Archaepoteryx |
Transtional fossil that links different birds to dinosaurs |
|
|
Continental drift |
Movement of the earth's crust resulting in the movement of the continents away from each other |
Pangea |
|
What does all life share? |
DNA and ATP |
|
|
What is an example of biochemical evolution? |
Superbacteria that have become antibiotic resistant. |
