Document Summary
Was a product of the coal mining, during 1770 and 1850 (industrial revolution) Coal particulate went up into the air and fell to the ground. 2 types: (can interbreed) typica (typical light like birch trees) With the increase of the war living (lots of coal burning) the frequency of the dark carbonaria expanded. With the cleaning up of the land and fossil fuel burning the typica begins to increase again with a decrease in carbonaria. Therefore, clean environment = typica is more hidden war environment = carbonaria is well hidden. Exam try and map organisms to the 5 conditions. Talked about jumping genes on the moths (barbara mcclintock) Also mentioned linneus (linnaean categories) nested hierarchy. Grouping based on similarities and differences vs. grouping based on order of dichotomous branching. Nested hierarchies vs. only monophyletic groups recognized. Linnaean levels important vs. not typically, morphology-based vs. often includes molecular data. Unfortunately, the field of cladistics is terminologically well-endowed (from text)
