ANT203H5 Lecture Notes - Lecture 2: Femur Neck, Bipedalism, Scientific Method
Document Summary
As we became more bipedal, chances of arthritis increases. As we became more bipedal, femoral neck of leg bone thickened. Charles darwin credited with theory of evolution by process of natural selection. What is science: the body of knowledge gained through observation and experimentation. Evolution common misconceptions: e(cid:448)olutio(cid:374) is (cid:862)o(cid:374)ly a theo(cid:396)y(cid:863, hu(cid:373)a(cid:374)s (cid:862)e(cid:448)ol(cid:448)ed(cid:863) f(cid:396)o(cid:373) (cid:373)o(cid:374)keys, evolution is a linear trend towards complexity. Misconceptions mostly occur because of not learning about it during high school. Some people still think evolution does not exist. Theory substantially verified through repeated testing of hypotheses. Examples of other scientific theories: theory of relativity, theory of gravity.
