What is evolution?
He is known as the Father of Evolution

The oldest fossil are found in what rock layers?
What is the bottom layer/deeper layers?
Similar structures that evolved from a common ancestor such as bones humans, cats, bats, and whales have in common.
What are Homologous Structures?
Any inherited trait that increases an organism's chance of survival is known as this.
What is an adaptation?
Populations that are more likely to survive a changing environment need to have lots of ...
variations
Physical Characteristics that are passed down to the next generation such as hair, eyes, height, weight, etc. Phenotype or genotype.
Phenotype
Preserved remains of ancient organisms
What are fossils?
The concept that organisms who are the best suited to their environment will be the most successful
What is survival of the fittest?
A mistake or change that occurs in the DNA sequence is called a ______________________.
What is a mutation?
The concept of humans selecting desired traits in species
What is artificial selection or selective breeding?
According to the modern theory of evolution, new traits are produced by....
What are mutations?
Inherited Characteristics that cannot be seen on the organism such inherited diseases, genetic disorders, etc. Genotype or phenotype.
genotype
This type of vestigial structure is found in our digestive system. This organ used to be used to digest cellulose for our ancient ancestors.
What is the appendix?
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?
What is Natural Selection?
Organs/ structures that no longer serve a purpose and have disappeared or reduced in size
Vestigial Organs/Structures
Being able to blend in with your environment.
camouflage
Study of how embryos develop similarly
Embryology
When an organism completely dies out.
What is Extinction?
Name one evidence of evolution
analagous structures, homologous structures, similar embryos, fossils, DNA analysis
Evolutionists believe that similar orgamisms evolved from a(n)
What is common ancestors?
speciation, new species
When one species changes into two or more different species
Speciation
Body structures on different organisms that are similar in function but did not evolve from the same ancestor (bird wing and butterfly wing)
What are Analogous Structures?
While in the Galapagos Islands, Darwin noticed that the Finches' beak shape had evolved based on the...
food source
Any fossil which gives us information about a transition from one species to another; helps support the Theory of Evolution
