Anthropology 361


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)
