Natural Selection
Natural differences in traits within the same species like fur color.
What is Variation.
An alteration in an organisms DNA structure.
What is Mutation?
Similar organisms that normally produce fertile offspring
What is a Species?
The thing that describes a group that shows of an ancestor and all of its descendants.
What is a Clade
The permanent removal of a species over time.
What is Extinction?
The Movement or transfer of alleles from one type of population to another.
What is gene flow?
The evolution in which occurs when individuals with certain traits are more likely to survive and reproduce than others.
What is Natural Selection?
A neighboring population, that each interbreeding with its neighbors and are arranged in a circular shape.
What is Ring Species?
The thing that represents the most recent common ancestor.
What is Node?
Physical features in different species that share a common ancestor.
What is Homologous Structures?
The name of the book Darwin first came up with the idea.
What is On the Origin of Species?
A random change in allele frequencies with a population that mechanism has a larger effect on smaller populations.
What is Genetic Drift?
The rapid that is most likely a single-generation forming a new, reproductive isolated species.
What is instantaneous speciation?
A taxon outside the rest of the group/away from the rest of the taxon on the tree.
What is an Outgroup?
Features or behaviors that have lost most or all of their original function through evolution.
What is Vestigial Structures?
What is the difference between natural selection and artificial selection?
Natural Selection is when the environment determines which organisms survive and reproduce.
Artificial Selection is when humans selectively breed organisms for the traits that they want.
A reduction in population size due to environmental events or human activities that causes a large loss of genetic diversity.
What is the Bottleneck Effect?
The three different types of speciation.
What is Allopatric Speciation, Sympatric Speciation, Instantaneous Speciation?
The acronym of LUCA.
What is Last Universal Common Ancestor?
The pattern of evolution during which new species evolve in short, rapid time then after long periods of stability.
What is punctuated equilibrium?
The difference of favorable and unfavorable Alleles
Favorable alleles are when they help the organism gain a selective advantage.
While unfavorable alleles show a disadvantage.
A loss of genetic variation that happens when a new, isolated population is put by a very small number of individuals from a larger population
What is The Founder Effect?
The difference between Hybrid inviability and Hybrid sterility.
Hybrid inviability means the hybrid offspring died before they reached maturity. While hybrid sterility means that the hybrid survives to adulthood but is unable to reproduce
Control genes that determine the basic body plan of an organism.
What is Hox Genes?
The Patterns in Macroevolution.
What is: 1. Gradualism and Punctuated Equilibrium 2. Extinction 3. Divergent evolution and Adaptive Radiation 4. Parallel Evolution 5. Convergent evolution 6. Coevolution
