A change in the DNA sequence
How well an organism is able to survive and reproduce in its environment
This person wrote On the Origin of Species after a long voyage to the Galapagos Islands
Who is Charles Darwin?
Preserved remains of ancient organisms
What are fossils?
What is natural selection?
A heritable trait that helps an organism better survive and reproduce in their environment
What is an adaptation?
When humans breed organisms for specific features
What is artificial selection?
All living things are trying to do two things:
What is Survive and Reproduce?
the combined genetic information of all members of a population
What is a Gene Pool?
A form of reproductive isolation in which 2 populations have differences in courtship rituals or other types of behaviour that prevent them from interbreeding
What is behavioural isolation?
The whale's pelvic bones
What is vestigial structure?
Has similar functions but different structures and do not share a common ancestor 
What are analogous structures?
change on a small scale, evolution in a single population over a short period of time
What is Microevolution?
formation of a new species
What is speciation?
Has similar bone structures and a common ancestor

What are homologous structures?
A decline in genetic variation when a small group becomes separated from a larger population
![]()
What is the founder effect?
When a species separates into 2 groups that are geographically isolated from each other, creating 2 separate species
What is geographic isolation?
A sharp decline in a population's genetic variation due to outside forces or random events
What is the bottleneck effect?
large-scale evolutionary changes that take place over a long period of time
What is Macroevolution?
A form of reproductive isolation in which 2 populations reproduce at different times
What is temporal isolation?
Had a previous theory of evolution that stated inheritance of acquired traits: acquired characteristics can be passed on to offspring
Who is Lamarck?
Includes the following: the fossil record, Geography, Anatomy, Embryology, and DNA Similarities
What is Evidence of evolution?
The five things that help push evolution and natural selection forward.
What is Inherited Variation, Overproduction, Fitness, and Limited Resources?
A diagram showing evolutionary relationships of organisms with a common ancestor resembles a tree
What is a phylogenetic tree?
Organisms moving from a population of one species to a separate population of the same species, changing the allele frequency or introducing new traits
What is gene flow
