This type of adaptation allows an animal to blend into the environment so the creature is not seen.
What is camouflage?
100
This theory says that species can gradually change over a long period of time
What is evolution?
100
This is essential for the continued survival of life on the planet.
What is variation?
100
A random change in allele frequency
What is genetic drift?
100
This is remains of living things that were trapped in the Earth and kept from decomposing.
What are fossils?
200
This happens when an animal evolves to look like another creature that is much more dangerous.
What is mimicry?
200
A well-supported testable explanation of what happened.
What is a scientific theory?
200
This consists of all genes, including all the different alleles that are present in a population.
What is a gene pool?
200
This happens when two populations are separated by geographic barriers such as rivers or mountains.
What is geographical isolation?
200
This allows scientists to determine the age of a fossil by looking at what rock layer it is in.
What is relative dating?
300
This is the result of adaptations
What is fitness?
300
This person's work caused Darwin to think about what factors influenced whether or not an organism survives.
Who is Malthus?
300
These are the two main sources of genetic variation
What are mutations and genetic shuffling?
300
This happens when two populations are capable of interbreeding but have differences in courtship rituals or other reproductive strategies that involve behavior.
What is behavioral isolation?
300
Scientists can determine the actual age of a fossil using this method. It involves radioactive atoms
What is absolute dating?
400
This is any inherited characteristic that increases an organism's chance of survival
What are adaptations?
400
These people caused Darwin to consider that his theory could be true since the earth is many millions of years old.
Who are Hutton and Lyell?
400
This can only change or alter existing traits, they do not create new traits.
What is a mutation?
400
This effect sees some traits become common because they were in the founding members.
What is the founder effect?
400
The organs may look the same from organism to organism. But they do not always serve an important function.
What are vestigial organs?
500
This process says that animals that are well suited to their environment will survive and produce lots of offspring.
What is survival of the fittest?
500
This person had an idea that the way organisms could evolve was by not using or using certain organs.
Who is Lamark?
500
Alleles in this combination they can be lethal and still be passed down from generation to generation
What is a heterozygous genotype?
500
This is a group of organisms that breed with one another and produce fertile offspring.
What is a species?
500
What principle states that all animals are related to one another.
