artificial selection
Individuals are ____________, populations __________
selected, evolve
Similar structures that evolved from a common ancestor such as bones humans, cats, bats, and whales have in common.
Homologous Structures
A change in DNA that can cause a new trait to appear in a population
what is a mutation?
Any inherited trait that increases an organism's chance of survival is known as this.
What is an adaptation?
Darwin was from the 1800's. What part of modern science did he lack knowledge of in order to better explain how traits were passed down from parent to offspring?
genetics or DNA knowledge
A record of Earth changing over a long period of time
What is fossil record?
Preserved remains of ancient organisms
What are fossils?
This term refers to different traits and alleles within a population.
What is variation?

what is most closely related?
Similarities between the bone structures of paws, hooves, wings, and fins are examples of this.
What are homologous structures?
the type of plate boundary that occurs when the plates move apart
divergent
The concept of humans selecting desired traits in species.
What is artificial selection?
Structures that have no apparent function and appear to be residual parts from a past ancestor
Vestigial Structures
the trait did humans develop that caused changes in foot structure as well as hip bone structure
what is bipedalism? (walking on two feet)
a change in DNA that can cause the appearance of new traits in a population
what are mutations?
Which term refers to the process by which individuals that are better suited to the environment survive and reproduce therefore passing down their genes to their offspring?
Natural Selection
