Lowest 3 only!
A group of similar organisms that can breed and produce fertile offspring.
What is species?
100
Selection by humans for breeding of useful traits from the natural variation among different organisms
What is artificial selection?
100
Traveled to the Galapagos Islands on the HMS Beagle and later wrote the book "The Origin of Species."
Who is Charles Darwin?
100
A structure that is present in an organism but no longer serves its original purpose (ex. hip bones in whales)
What are vestigial structures?
100
The struggle between organisms to survive as they attempt to use the SAME limited resource
What is competition?
200
Lowest 3 only!
A trace of an ancient organism that has been preserved in rock
What is fossil?
200
Difference among members of a species.
What is variation?
200
Organisms make more __________ than will actually survive.
What is offspring?
200
Lowest 3 only!
Genetic information that can be used as evidence of evolution between organisms.
What is DNA?
200
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?
300
A trait that helps an organism survive and reproduce
What is adaptation?
300
Structures in different species that are similar because of common ancestry.
What are homologous structures?
300
All the fossils throughout the history of the Earth that are used as evidence of evolution.
What is the fossil record?
300
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.
300
These organisms have amniotic eggs.
Who are lizards and birds
400
Change in a kind of organism over time; process by which modern organisms have descended from ancient organisms.
What is evolution?
400
These changes in DNA are responsible for the variation within species
What are mutations?
400
An ancestral species from which later species evolved
What is common ancestor?
400
This is the cause of speciation when land features seperate two populations.
What is geographic isolation?
400
Lowest 3 only!
A mistake or change that occurs in the DNA sequence is called a ______________________.
What is a mutation?
500
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?
500
Study of developing embryos used as evidence of evolution.
What is Embryology?
500
Lowest 3 only!
When an organism completely dies out.
What is Extinction?
500
This is the tendency of individual genetic characteristics in a population to differ from one another
What is genetic variation?
500
This creature is thought to be the ancestor of most land animals.
Who is Tiktaalik?
600
An example of this process is humans selecting corn kernels of teosinte and creating the evolution of modern corn.
What is artificial selection?

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?
