Group 1
Who proposed the theory of evolution by natural selection
Charles Darwin
Preserved remains of ancient organisms
Fossils
A characteristic that helps an organism survive
Adaptation
When populations reproduce at different times, preventing them from mating with each other.
Temporal isolation
A animal, plant, or any living thing.
Organism
Refers to the variety of living things
Biodiversity
A tool used to identify organisms through a series of paired choices.
Dichotomous key
The process by which one species gives rise to two or more distinct species.
Speciation
When differences in courtship or other mating behaviors prevent populations from reproducing with each other.
Behavioral isolation
The taxonomic rank directly below order and directly above genus.
Family
Process by which evolution occurs
Natural Selection
The process of organizing organisms into groups based on similarities and evolutionary relationships.
Classification
The two-part scientific naming system for organisms.
Binomial nomenclature
A condition in which populations cannot successfully reproduce with each other, or otherwise do not exchange genes through reproduction.
Reproductive isolation
The differences in the physical traits of organisms
Variation
Changes over time
Evolution
Diagram showing the evolutionary relationships between organisms.
Cladogram
Darwin was from the 1800's. What part of modern science did he lack knowledge of in order to better explain how traits were passed down from parent to offspring?
Genetics and DNA
When a physical barrier, such as a river or mountain range, separates populations and restricts gene flow.
Geographic isolation
A group of organisms whose members can naturally reproduce with one another and produce fertile offspring, under the traditional biological species concept.
Species
Islands that Darwin visited
Galapagos
The study of fossils or extinct organisms.
Paleontology
New organisms come into or out of a population
Gene Flow
An ancestral organism or population from which two or more evolutionary lineages descended.
Common ancestor
The ultimate source of genetic variation
Genetic Mutation
