Lowest 3 only!
A group of similar organisms that can breed and produce fertile offspring.
What is species?
Selection by humans for breeding of useful traits from the natural variation among different organisms
What is artificial selection?
Traveled to the Galapagos Islands on the HMS Beagle and later wrote the book "The Origin of Species."
Who is Charles Darwin?
A structure that is present in an organism but no longer serves its original purpose (ex. hip bones in whales)
What are vestigial structures?
The struggle between organisms to survive as they attempt to use the SAME limited resource
What is competition?
Lowest 3 only!
A trace of an ancient organism that has been preserved in rock
What is fossil?
Difference among members of a species.
What is variation?
Organisms make more __________ than will actually survive.
What is offspring?
Lowest 3 only!
Genetic information that can be used as evidence of evolution between organisms.
What is DNA?
Lowest 3 only!
A natural process resulting in the evolution of organisms best adapted to the environment ex. fastest, smartest, quietest, loudest, best eyesight, etc.
What is survival of the fittest?
A trait that helps an organism survive and reproduce
What is adaptation?
Structures in different species that are similar because of common ancestry.
What are homologous structures?
All the fossils throughout the history of the Earth that are used as evidence of evolution.
What is the fossil record?
Why did the population of pepper moths change?
Industrial revolution, smoke, trees turning black, the mutated black moths were able to survive and reproduce better and their population grew.
These organisms have amniotic eggs.
Who are lizards and birds
Change in a kind of organism over time; process by which modern organisms have descended from ancient organisms.
What is evolution?
These changes in DNA are responsible for the variation within species
What are mutations?
An ancestral species from which later species evolved
What is common ancestor?
This is the cause of speciation when land features seperate two populations.
What is geographic isolation?
Lowest 3 only!
A mistake or change that occurs in the DNA sequence is called a ______________________.
What is a mutation?
Process by which individuals that are better suited to their environment survive and reproduce most successfully; also called survival of the fittest
What is natural selection?
Study of developing embryos used as evidence of evolution.
What is Embryology?
Lowest 3 only!
When an organism completely dies out.
What is Extinction?
This is the tendency of individual genetic characteristics in a population to differ from one another
What is genetic variation?
This creature is thought to be the ancestor of most land animals.

Who is Tiktaalik?
An example of this process is humans selecting corn kernels of teosinte and creating the evolution of modern corn.
What is artificial selection?
Lowest 3 only!
This is the closest relative to modern whales.
What is the hippopotamus?
Lowest 3 only!
Archaeopteryx demonstrates a transition between these two groups of organisms.

What are dinosaurs and birds
These are three examples of vestigial structures in humans.
What are the tailbone, appendix, wisdom teeth?
This now extinct species was the closest relative to humans and even is thought to have interbred with them in Europe.
Who are neanderthals?
