100 – EVIDENCE
THIS TYPE OF EVIDENCE EXPLAINS WHY AT
CERTAIN TIMES DURING DEVELOPMENT
VERTEBRATE SPECIES LOOK VERY SIMILAR
100
EMBRYOLOGY
200 – EVIDENCE
THIS STRUCTURE EVOLVES INDEPENDENTLY IN
UNRELATED SPECIES LIVING IN SIMILAR
ENVIRONMENTS
200
ANALOGOUS STRUCTURES
300 – EVIDENCE
THIS TYPE OF EVIDENCE SUPPORTS THE
THEORY OF MICROEVOLUTION
300
BIOCHEMISTRY
400 – EVIDENCE
THIS STRUCTURE WAS ONCE FUNCTIONAL IN
AN ANCESTRAL ORGANISM
400
VESTIGIAL
500 – EVIDENCE
THIS LAW STATES THAT WITHIN ROCK LAYERS
THE OLDEST LAYER IS ON THE BOTTOM &
YOUNGEST LAYER IS ON TOP
500
LAW OF SUPERPOSITION
100 – PATTERNS
THIS PATTERN FORMS MULTIPLE SPECIES
FROM ONE COMMON ANCESTOR
100
ADAPTIVE RADIATION
200 – PATTERNS
THIS PATTERN EXPLAINS WHY TWO RELATED
SPECIES BECOME LESS & LESS SIMILAR
200
DIVERGENT EVOLUTION
300 – PATTERNS
THIS PATTERN EXPLAINS WHY WHALES &
SHARKS BOTH HAVE SIMILAR ADAPTATIONS
TO HELP THEM SURVIVE IN THE OCEAN BUT ARE
UNRELATED SPECIES
300
CONVERGENT EVOLUTION
400 – PATTERNS
THIS PATTERN EXPLAINS WHY BEES &
FLOWERS EVOLVE TOGETHER OR MUTUALLY
400
COEVOLUTION
500 – PATTERNS
DARWIN’S FINCHES ARE AN EXAMPLE OF THIS
TYPE OF PATTERN OF EVOLUTION

ADAPTIVE RADIATION
100 – POPULATION GENETICS
THIS IS THE TOTAL GENETIC INFORMATION
AVAILABLE IN A POPULATION

GENE POOL
200 – POPULATION GENETICS
THIS IS THE STABILITY OF ALLELE FREQUENCIES
ACROSS GENERATIONS
200
HARDY-WEINBERG EQUILIBRIUM
300 – POPULATION GENETICS
THIS PROCESS EXPLAINS HOW EVOLUTION
OCCURS WITHIN GENOTYPES RATHER THAN
PHENOTYPES
300
NATURAL SELECTION
400 – POPULATION GENETICS
GIVE THE EQUATION FOR FINDING THE
PHENOTYPIC FREQUENCY
400
# OF INDIVIDUALS WITH A CERTAIN
PHENOTYPE DIVIDED BY THE TOTAL # OF
INDIVIDUALS
500 – POPULATION GENETICS
NAME THREE THINGS THAT MUST OCCUR IF
ALELLE FREQUENCIES ARE TO REMAIN THE
SAME
500
NO MUTATIONS, NO GENE FLOW, LARGE
POPULATION, RANDOM MATING, NO SELECTION
100 – DISRUPTION OF GENETIC EQUILIBRIUM
THIS PROCESS EXPLAINS HOW GENES FLOW
FROM ONE POPULATION TO ANOTHER
100
MIGRATION
200 – DISRUPTION OF GENETIC EQUILIBRIUM
THIS PROCESS EXPLAINS WHY ORGANISMS
MATE WITH OTHER ORGANISMS WITH
SIMILAR PHYSICAL CHARACTERISTICS
200
NON-RANDOM MATING
300 – DISRUPTION OF GENETIC EQUILIBRIUM
THIS TYPE OF SELECTION DESCRIBES HOW THE
AVERAGE FORM OF A TRAIT IS MORE FIT THAN
THE EXTREME FORMS
300
STABILIZING SELECTION
400 – DISRUPTION OF GENETIC EQUILIBRIUM
THIS TYPE OF GENETIC DRIFT OCCURS WHEN A
POPULATION IS DRAMATICALLY EFFECTED BY A
NATURAL DISASTER OR HUMAN IMPACT
400
POPULATION BOTTLENECK
500 – DISRUPTION OF GENETIC EQUILIBRIUM
THE PEPPERED MOTH CHANGING IN
COLORATION AFTER THE INDUSTRIAL
REVOLUTION IS AN EXAMPLE OF THIS TYPE OF
SELECTION
500
DIRECTIONAL SELECTION
100 -- SPECIATION
THIS CONCEPT DEFINES A SPECIES
ACCORDING TO ITS STRUCTURE &
APPEARANCE
100
MORPHOLOGICAL CONCEPT OF SPECIES
200 -- SPECIATION
NAME ONE LIMITATION OF THE BIOLOGICAL
SPECIES CONCEPT
200
NOT HELPFUL FOR THOSE ORGANISMS
ALREADY EXTINCT OR ASEXUAL
300 -- SPECIATION
THIS TYPE OF ISOLATION IS THE PHYSICAL
SEPARATION OF POPULATIONS
300
GEOGRAPHIC ISOLATION
400 -- SPECIATION
THIS RATE OF SPECIATION OCCURS DURING
PERIODS OF RAPID GENETIC CHANGE
400
