Natural Selection
This man is best known for his theory of Evolution via natural selection.
Darwin
This is a diagram that shows evolutionary relationships
Phylogenetic Tree
or
Cladogram
These are similarities between traits/features in different species
Homologies
Random changes in DNA are called .....
mutations
Organisms with traits that are better suited to their environment are more likely to survive and pass on those advantages to their offspring. This is called....
Natural Selection
OR
survival of the fittest
When an entire species of an organism no longer exists. We say the species is "...."
Extinct
This type of homology shows structural similarities between organisms (ex. bones, skull shape)
Anatomical
These are advantageous *good* traits that can be passed down to offspring
Adaptations
The theory of evolution via natural selection states that all species on Earth evolved from a common "...."
Ancestor
Populations can evolve. These cannot.
Individuals
This type of homology shows similarities between DNA sequences.
Molecular
Genetic variation comes from mutations. Mutations can be good, bad, or "....."?
Neutral
Being able to survive and reproduce is called .....
Fitness
These preserved remains of ancient plants/animals provide evidence for evolution
Fossils
This type of homology shows common structures in developing embyros
Embryological
A group of organisms that can interbreed and produce viable and fertile offspring is called a "...."
Species
This factor, plays a huge role in natural selection.
Environment
This is the leading cause of genetic variation.
Mutations in DNA
This is a structure that an organism has, but doesn't use
Vestigial
All living organisms of the same species living in the same area is called a "...."
Population
