Evolution
What is the definition of evolution
This pattern of evolution occurs when species change slowly over time.
Gradualism
This mechanism occurs when individuals with beneficial traits survive and reproduce more successfully.
natural selection
Who developed the theory of natural selection?
Charles Darwin
What is paleontology?
The study of fossils
Who is the scientist most associated with the theory of evolution?
Charles Darwin
This pattern describes rapid evolution followed by long periods of little or no change.
punctuated equilibrium
Random changes in DNA that create new alleles are called this.
mutations
Another name for natural selection
survival of the fittest
What is embryology?
the study of embryos
A trait that improves survival or reproduction.
When unrelated species evolve similar traits due to similar environments, this pattern is occurring.
convergent evolution
This mechanism happens when individuals move into or out of a population, changing allele frequencies.
gene flow
Explain the process of natural selection
This is the process by which organisms better adapted to their environment survive and produce more offspring.
Define homologous structures and give an example
same structure, different function

What does “survival of the fittest” mean?
Organisms best adapted survive and reproduce.
This pattern occurs when two species evolve in response to each other.
coevolution
A natural disaster randomly killing part of a population is an example of this type of genetic drift.
genetic drift
Give an example of an adaptation
Answers may vary
What is a vestigial structure and give an example
"left-over" organs from ancestors
answers vary
What is extinction?
When a species completely dies out.
When one ancestral species evolves into many different species, this pattern is called this.
divergent evolution
This mechanism of evolution occurs when individuals choose mates based on specific traits, such as bright feathers or courtship behaviors.
Non-random mating
Do individuals evolve, or do populations evolve?
Populations
What is an analogous structure and give an example
different structure, same function
answers vary
