Evolution
What is Law Of Superposition?
The prediction of the top rock layers are the youngest and the bottom rock layers are the oldest.
What is Analogous Structure?
Body parts that share a common function, but not structure.
What is Stabilizing Structure?
When natural selection favors one extreme trait.
What is Asexual Adaptation?
Process by which a single parent reproduces by itself.
What is Genetic Drift?
Random change in allele frequencies that occurs in small population.
What is Biological Resistance?
The natural or genetic ability of an organism to avoid or repel attack by biotic agents.
What is Homologous?
Structures in a different function/species but are similar because of common ancestry.
What is Speciation?
The formation of new and distinct species in the course evolution.
What is Divergent Evolution?
When two or more species share a common ancestor become more different overtime.
What is Prokaryote?
An organism without a nucleus or membrane bound organelles.
What is Relative Dating?
A technique used to determine which of two fossils is older.
What is a Vestigal Structure?
A structure that is present in an organism but no longer serves its original purpose (ex; wisdom teeth, human tailbones)
What is Species?
A group of similar organisms that can breed and produce fertile offspring.
What is Convergent Evolution?
Unrelated organisms independently evolve similiarities when adapting to similiar environments.
What is Eukaryote?
An organism with a nucleus and membrane bound organelles.
What is Theory Of Acquired?
Theory Of Acquired is a theory that species acquire traits during their lifetime and pass on to their offspring
What is Directional Selection?
When natural selection favors one of the extreme variations of a trait.
What is Gene Flow?
Movement of alleles from one population to another.
What is Punctuated?
When species evolve during short periods of rapid change.
What is Aerobic?
A requirement for oxygen.
What is Natural Selection?
Natural selection is a process in which individuals that have certain inherited traits tend to survive and reproduce at higher rates than other individuals.
What is Disruptive Selection?
When natural selection favors both extremes of phenotype range.
What is Adaption?
A trait that helps an organism survive and reproduce.
What is Genetic Pool?
Combined genetic information of all the members of a particular population.
What is Fitness?
How well an organism can survive and reproduce in its environment.
