Shaping evolutionary theory I
100
The Scientist who developed the theory of evolution
Who is Charles Darwin
100
How scientists can see evidence of evolution
What are Fossils
100
Structures not inherited from a common ancestor but have similar purposes
What are Analogous structures
100
A trait shaped by natural selection to increase the survival or reproductive success of an organism
What is an Adaptation
100
a principle that states: When allelic frequencies remain constant, a population is in genetic equilibrium
What is the Hardy-Weinberg principle.
200
Cumulative changes in groups of organisms through time
What is evolution
200
Primitive features that appear in ancestral forms
What are Ancestral traits
200
Anatomical structures inherited from a common ancestor
what are homologous structures
200
A measure of the relative contribution that an individual makes the the next generation
often measured as the number of reproductively viable offspring that an organism produces
What is fitness
200
individuals choosing their mates based on their genotypes or phenotypes
nonrandom mating
300
Variations that increase reproductive success will have a greater chance of being passed down
What is Reproductive Advantage
300
Newly evolved features, that do not appear in the fossils of common ancestors
What are Derived traits
300
Structures that have either a reduced function or no function in an adult organism
What are vestigial structures
300
one species evolves to resemble another
What is mimicry
300
A random change in genetic material
What is Mutation
400
The reason finches on different Islands have different beaks
What is Natural Selection
or
Because they needed to eat different kinds of food
400
why do analogous structures exist
The species lived in similar environments and needed the structure for survival
400
What are homologous structures
400
Blending in with your environment
Camouflage
400
new genes enter the population or genes leave the population
What is geneflow
500
The four basic principles of Natural Selection
What are Variation, Heritability, overproduction, and reproductive advantage
500
Why do vestigial structures exist?
These structures were functional in ancestral organisms

Bacteria adapting to be resistant to antibiotics
Antimicrobial resistance
500
Any change in the allelic frequencies in a population that results from chance
what is genetic drift
