Document Summary
# and type of ptc alleles determined if you are a taster or not: more aav = more likely to be non-taster. Molecular clock hypothesis = set the clock by . Evidence or african origin: more mtdna variability in africans showing they"ve had more time to evolve, african populations have the oldest mtdna lineages as shown in phylogenic tree, founder effect = africa has home base of dispersal routes. Taxa = classification (kingdom, phylum, class, order, etc. ) Taxonomy = field of bio that seeks to classify diversity. Systematics = field that includes nomenclature (assigning names) and phylogenetics (reconstruction of evolutionary relationships) Scientific name = genus, specific epithet: format: drosophilia melanogaster then later d. melanogaster. Calibrate w/ fossil or geological evidence: divergence. Gibbons bonobos/chimps(6mya) humans/neanderthals (diverged 500 thousand years ago) Field diaphragm v. condenser: field diaphragm is the large dial (0-100) Close to get hexagon: condenser diaphragm lever = switchy thing, condenser = small focusing knob on the side.
