Natural Selection
the process by which new species were brought into existence.
Evolution shows us that species are not immutable but that they change over time through natural selection
Species
a group of related organisms that share a distinctive form and are capable of interbreeding and producing an offspring that interbreeds
Speciation is the evolutionary process by which new biological species arise
Evolution is considered science because it is observable and testable
