Natural Selection
Types of Natural Selection
100
Selective breeding for specific traits
Artificial Selection
100
Which animal is more closely related to the gray wolf? The dog or the gray wolf?
Dog
100
the adaptations that produce the highest fitness will become more prominent in the population
Natural Selection
100
What would cause one animal to have higher fitness than another?
Having more offspring.
100
Normal Distribution is also called
Bell Curve
200
Similar structures in organisms that share a common ancestor
Homologous Structure
200
Which animals do not have amniote eggs?
Amphibians, fish, and sharks
200
how well an organism can survive and reproduce in its environment
Fitness
200
change in allele frequency due to random occurrences
Genetic Drift
200
One extreme form now provides higher fitness
Directional Selection
300
Similar structures that have the same function, but organisms do NOT share a common ancestor. These structures have evolved independently
Analogous Structure
300
The wings of a bird and a moth and examples of what types of structures?
Analogous Structures
300
heritable characteristic that increases an organism’s fitness (can be physical or behavioral)
Adaptation
300
What populations that are not experiencing natural selection have
Genetic Equilibrium
300
Average traits now provides higher fitness
Stabilizing Selection
400
Structures that have lost their original function, because that organism no longer needs them
Vestigial Structure
400
The Pelvis and Femur bones of a whale are examples
of which type of structure?
Vestigial Structures
400
all the different alleles present in a population
Gene Pool
400
What are the three types of speciation
Geographic Isolation (physical barrier)
Temporal Isolation (time)
Behavioral Isolation
400
Both extreme traits now provides higher fitness. Lowest fitness in the center. Distribution splits into two curves
Diversifying Selection
500
Chart showing the order that specific organisms have evolved from a common ancestor
Cladogram (phylogenetic tree)
500
What are the two models of evolution
Gradualism and Punctuated Equilibrium
500
percentage of an allele within the population
Alelle Frequency
500
List 3 sources of genetic variation
Mutation/ Translocation, Crossing Over, Independent Assortment, Sexual Reproduction, Immigration
