ANT 101 Lecture Notes - Lecture 22: Piltdown Man, Biostratigraphy, Dendrochronology
Document Summary
Examination of the morphology or structure of skeletal remains used to infer evolutionary relationships with other specimens. Determines only whether an object is older or younger than another but not it"s exact age. Based on the geological principle of superposition. Lower strata (layers) are older than higher strata. Applies to buried bones and groundwater seepage. If there"s more fluorine it"s older than the one with less fluorine. This skeleton seemed to fit the pattern of what people were expecting, discovered in england, it was discovered that this was an archaic skull, what was an anatomically modern human with a completely modern orangutan jaw. When rock is formed, the magnetic particles align towards the pole. Comparison of animal remains to determine similarity in time level. Radioactive decay how fast do they lose these particles. Time it takes for the original amount of material to be reduces by one half. This can date anything that used to be alive.
