Evolution ✔Correct Answer--The changing of an entity over a period of time
Darwin ✔Correct Answer--Developed ideas on natural selection and heritable traits
Origin of species ✔Correct Answer--Darwin's book written about his findings on the Galapagous
Galapagos Islands ✔Correct Answer--Key location of Darwin's studies of natural selection; off the
west coast of South America
Finches ✔Correct Answer--Key species in Darwin's studies of evolution
Mutation ✔Correct Answer--A base pair or set of base pairs on a strand of DNA are changed; rare
and random
Natural selection ✔Correct Answer--A mechanism of evolution in traits that increase survival rate
are favored and increase within a population
Genetic drift ✔Correct Answer--Movement towards a specific allele or trait; can result in fixation;
Can be random.
Gene flow ✔Correct Answer--The movement of genes/alleles from one population to another
Non-random mating ✔Correct Answer--Certain traits enhance an individuals attractiveness and
ability to mate
Stabilizing selection ✔Correct Answer--A type of natural selection; median traits are favored
Directional selection ✔Correct Answer--A form of natural selection; one extreme version of a trait

favored.
Balancing selection ✔Correct Answer--A form of natural selection; variation is favored
Oscillating selection ✔Correct Answer--A form of natural selection; Different versions of the trait
are favored at different times; occurs repetitively
Sexual selection ✔Correct Answer--A form of natural selection; non-random mating influences the
traits and genotypes present in a population.
Heterozygote advantage ✔Correct Answer--A case in which individuals with a dominant and
recessive allele have some kind of advantage; ex. sickle cell anemia and malaria.
Intersexual selection ✔Correct Answer--Selection between sexes; female choice
