BIOL 3200 Lecture Notes - Lecture 5: Vitalism, Mendelian Inheritance, Cell Theory
Document Summary
The organic connection: evolution pervades cell biology, there is a connection between cell theory and mendelian genetics. The cell theory a new generation of biologists: early 19th century was the birth of biology, all organisms at one time began as a cell so all are linked in some way. Issues about materialism and vitalism: scientific discovery is more than what meets the eye, discovery (cid:272)a(cid:374)(cid:374)ot (cid:271)e attri(cid:271)uted to o(cid:374)e i(cid:374)di(cid:448)idual it is a (cid:272)o(cid:374)tri(cid:271)utio(cid:374) (cid:271)y (cid:448)arious individuals. Reification: changing a process into a thing (thingification, turning a process into a concrete thing such as a discovery. Birth of the germ theory of disease: development of microscopy occurred mainly in germany. Pleiomorphism: nageli: bacteria were highly plastic and changed into diverse kinds, germ theory: one germ one disease. Miller-urey experiment (1953: double helix structure was discovered in 1953, they put methane, ammonia, hydrogen, water and electric sparks in a flask and left it for days yielded 7 a(cid:373)i(cid:374)o a(cid:272)ids.
