What Is Evolution?
A change in traits within an individual organism over its lifetime,
What is NOT evolution?
The only driver that consistently leads to adaptation
What
is fitness?What is natural selection?
Both founder effect and bottleneck effect are types of this evolutionary mechanism
What is genetic drift?
Selection that favors one extreme phenotype
What is directional selection?
Evolution resulting in similar traits in unrelated species
What is convergent evolution?
A change in allele frequencies in a population over time
What is evolution?
The random change in allele frequencies due to chance
What is genetic drift?
A small group breaks off to colonize a new area
What is the founder effect?
Selection that favors the average phenotype
What is stabilizing selection?
Evolution from a common ancestor leading to different species
What is divergent evolution?
The level of biological organization at which evolution occurs
What is a population?
The movement of alleles between populations
What is gene flow?
A population is drastically reduced by a natural disaster
What is the bottleneck effect?
Selection that favors both extreme phenotypes
What is disruptive selection?
Bird wings and insect wings are examples of these
What are analogous structures?
The source of genetic variation that evolution acts on a molecular level
What is mutation?
This driver introduces new alleles into a population
What is mutation?
Why both effects reduce genetic variation
What is random sampling of alleles?
The type of selection that often reduces variation
What is stabilizing selection?
Bat wings and whale flippers are examples of these
What are homologous structures?
True or False: Evolution always results in organisms that are more “advanced”
What is false?
A driver that affects genotype frequencies but not allele frequencies
What is non-random mating?
Which effect is more likely caused by disease, fire, or overhunting
What is the bottleneck effect?
The type of selection most likely to lead to speciation
What is disruptive selection?
The type of evolution most strongly supported by homologous structures
What is divergent evolution?
