Mechanics of Evolution
The movement/flow of alleles from one population to another
what is gene flow?
Acronym stating evidences for Evolution
What is FAME?
Process of a new species being created
What is speciation?
Organisms that share a recent common ancestor build up enough differences they become TWO different species (Hint: NOT SPECIATION)
What is divergent Evolution?
The Cell that is formed after fertilization
What is a zygote?
A type of Natural Selection where mating preferences drives evolution
what is sexual selection?
Evidence that analyzes embryos of different species look similar early in development
What is Embryology?
What is allopatric speciation?
Evolution where unrelated species develop similar traits
What is Convergent Evolution?
Describes an organisms ability to survive and reproduce in its environment
What is Fitness?
humans choosing which traits get passed down in a population
what is artificial selection
Physical, historic evidence of organisms
What are Fossils?
Isolation where fertilization happens but the children cant reproduce/ are sterile.
What is hybrid sterility?
Evolution where one species gives rise to MANY others.
What is Adaptive Radiation?
A situation where a trait becomes more common because it increases fitness
What is adaptation?
Evolution that is caused by random events
What is genetic drift?
Best evidence for evolution
What is molecular evidence?
Speciation that happens when organisms live in the same habitat/ without a physically barrier.
what is sympatric speciation?
Evolution that is caused by the relationship between two species, like host and parasite.
Structures with similar function but unsimilar structure
What are Analogous Structures?
type of genetic drift when genetic variability is reduced due to a small group of individuals being separated from the larger, more genetically diverse group.
what is founders effect?
Structures that no longer exhibit a function that serve as evidence for Evolution
What are Vestigial Structures?
Sperm is transfered but egg is not fertilized
What is Gamete Mortality?
Gradual Divergence, some populations can interbreed, but some can not.
When the average trait is selected for
What is stabilizing selection?
