Terms/Vocab
Question | Answer |
---|---|
Paleoanthropology | (prospecting for fossils) Systematic study of fossil evidence for human evolution (Artifacts, traces, impressions and fossils included) |
Archeology | looking for new fossils |
Lab Analysis | using old fossils and techniques to stimulate new hypotheses analyzing the physical characteristics |
Jean B. Lamarck | Inheritance of aquired characteristics was the right idea VOLISM: determination to develop fitness over life span CANNOT be passed on to offspring WRONG IDEA, difference between sex cells vs. Body Cells |
Adaptive Radiation | Species separated by genetic reproductive boundary that hinders the ability to mate successfully with other species |
Community | Share common genetic resources |
Separation | Inability to mate with other groups |
Allopatric Speciation | Geographic Isolation -> Reproductive Isolation |
Micro-Evolution | Evolutionary gene changes in frequency within populations by generations |
Macro-Evolution | Longterm evolutionary changes as a whole unified population |
Mophology | Typological species concept physically based distinguishing traits |
Graded | Boundaries between species are arbitrary Anagenesis vs. Cladogenesis |
Anagenesis | (single) |
Cladogenesis | "Clade": Boundaries between are well defined |
Homology | Similar morphologies shared by 2 species DUE TO COMMON ANCESTORS ex. Humerous Bone: Forelimb pattern of design is common but different functions |
Analogy | Similar Morphology shared by 2 species BASED ON FUNCTION -feels more coincidental (ex. Brid Wing, Insect Wing, Bat Wing all developed to fly but common ancestor didn't have wings) |
