Early Study of Evolution
The gradual change in species over time
What is evolution?
A process in which individuals that have certain inherited traits tend to survive and reproduce at higher rates than other individuals because of those traits
What is natural selection?
Ability of an organism to survive and reproduce in its environment
What is fitness?

What is Charles Darwin?

What is artificial selection?

What is an adaptation?
An error in gene replication that leads to a change
What is a mutation?
Movement of alleles into or out of a population due to the migration of individuals to or from the population
What is genetic flow?

What is the Galapagos Islands?
The name of the book Darwin published his ideas in about the theory of evolution
What is The Origin of Species?
A change in the allele frequency of a population as a result of chance events rather than natural selection.
What is genetic drift?
The theory that states organisms can change during their lifetime by selectively using parts of their body or not
What is Lamarck’s Theory of Transformation?
Darwin identified three factors that affect the process of natural selection
What is overproduction, variation, and competition?
Who said "It is not the strongest of the species that survives, not the most intelligent that survives. It is the one that is most adaptable to change"
