- it takes many generations to take effect
- individuals with when compared to other members of individuals have a distinct trait that gives them an advantage in survival or reproduction. a selective disadvantage is a trait which leaves the species at a disadvantage to survive and reproduce.
- individual variation, heritable traits, differential survival and reproduction, survival and reproduction are tied to heritable traits.

5 True/False Questions
what is the ultimate source of genetic variation → a genetic constraint that prevents an organism from making a change that would improve its fitness because it lacks the prerequisite genes.
overtime do species develop more complex traits due to evolution → struggle for existance among individuals, there are differences in survival and reproduction among individuals, over time differential survival and reproduction changes the population
Qualitative traits → discrete and categorical such as presence or absence of a particular structure or the state of a color,can be binary or multistate
thales → gave natural explanations to natural things
HLA genes → code for immunity and H-W test proved evolution was occuring
