- a the study of allele frequencies of populations and how they change over time. It is based on mendelian genetics.
- b not due to inheritance similarity is the result of convergence (parallel evolution) where different organisms adapt for similar functions in similar environments in unrelated Lineage's like birds and bats both have wings.

5 True/False Questions
Reliablity → that which when put to the test turns out to be true
Derived traits → trait that is a reduced or incompletely developed structure that has no function or has reduced function but is clearly similar to functioning organs on closely related species.
four criteria of theories → must be tested, must be falsifiable, cannot be proven only confirmed or disconfirmed, must be subject to revision or change.
Fitness trade-off → a change in allele frequencies occurring due to genetic drift when a new population is established from a small sample of the original population called a founder event
five concepts of the modern synthesis → traits are genetically based, continuous characters under mendelin control like discontinuous ones, species are variable based on location, evolution was changes in allele frequency over time, change over time was due to natural selection and random allele changes or mutation
