Document Summary

1. 5 -- explain the (1) relationship btwn a hypothesis and a prediction and (2) why experiments are convincing ways to test predictions. 25. 3 -- explain the difference between biological and everyday english definitions of fitness, adaptation, and selection. Fitness is ability to produce viable, fertile offspring, relative to that ability in other individuals in. Adaptation is heritable trait that increases fitness of individual in particular environment relative. Selection increases fitness and leads to adaptation. to individuals lacking trait. increases fitness. Biological species concept uses reproductive isolation as criterion to identify species. Morphospecies concept identifies species using distinctive morphological traits. Phylogenetic species concept identifies species as smallest monophyletic groups on tree of life. 28. 1 -- reading phylogenetic tree & concept of parsimony. Parsimony : choose simplest scientific explanation that fits the evidence. In tree building, all other things being equal, best hypothessis is one that requires fewest evolutionary changes. 29. 1 -- explain the difference between bacterium, archaeon, and eukaryote.
