Change over time Evolution
All living things share a Common Ancestor
"Father" of Evolution Charles Darwin
Ship that Darwin sailed on for 5 years Beagle
Evolution occurs through the process of Natural Selection
Changes that help an organism survive and reproduce Adaptations
The key to evolution Reproduce successfully
Fossils, vestigial structures and comparing organisms all provide what for evolution Evidence
Solidified remains or imprint of a once living organism Fossil
Remnant of a once-useful structure Vestigial Structure
The process by which organisms with favorable traits survive and reproduce Natural Selection
Overproduction, Genetic Variation, Struggle to Survive, and Successful Reproduction are the four stages of Natural Selection
Production of more offspring than will survive Overproduction
Individuals in a population are slightly different Genetic Variation
Individuals compete for resources Struggle to Survive
Change in a gene Mutation
Populations that can produce offspring that can have more offspring are said to be the same Species
The process by which two populations of the same species become so different that they can longer interbreed Speciation
Separation, Adaptation and Division are all possible explanations for Speciation
When a portion of the population is physically isolated from the others due to a mountain, lake, canyons, natural disaster Separation
When a species dies out completely Extinction
Metaphor for the concept of Natural Selection Survival of the fittest

Which kingdom contains the oldest living organisms, prokaryotic cells Archaebacteria
Which kingdom contains common prokaryotic cells Eubacteria
Organisms that eat other organisms Consumers
Organisms that make their own food Producers
Organisms that break down nutrients in dead organisms Decomposers
A new part of an organism grows off the old one Regeneration
A part of an organisms falls off and grows into a new one Budding
Which protist uses flagellum for movement, is green and makes its own food Euglena
Which protist uses pseudopods for movement Amoeba
Which protist uses cilia for movement Paramecium
