All of the fossils ever found on the Earth make up the____?
The Fossil Record

Who was Charles Darwin?
He was a British Naturalist who first suggested the theory of evolution by natural selection. (answers may vary)
100
What are adaptations?
An inherited trait that increases an organism's chance of surviving and reproducing in its environment
100
Scientists use molecular biology to determine how two species are related by comparing the genes in one species to genes... a.) in extinct species b.) in related species c.) in human species d.) in related fossils
b.) in living species that are related.

Which process uses a code on an RNA molecule to make a protein? a.) Mutation b.) replication c)transcription d.) translation
D.) Translation

Name two different ways fossils form (not what type of fossils are their)
Mineralization and Carbonization

What is the full name of the ship he voyaged on for 5 years?
HMS Beagle

What are the four characteristics that are needed to drive the process of natural selection
Reproduction=>Variation=> Competition=> Selection
200
What type of body parts/structures lose their original function through the process of evolution? Give an example
Vestigial Structures, pelvis of a whale, human tail bone, eye 's on a blind cave salamander.....

Which is the sequence by which natural selection works? a.) selection ->adaptation->variation b.) selection->variation-> adaptation c.) variation->adaptation->selection d.)variation->selection-> adaptation
d.)variation->selection-> adaptation

What is the geologic time scale and why is it important?
The geologic time scale is a chart that divides earths history into different time units. The time scale is important because scientists can use it to determine what type of organisms lived during that period as well as track the evolutionary process.

What did Darwin noticed about all of the species on the Galapagos Islands and he went from island to island that led to his groundbreaking theory?
He noticed tortoises, mockingbirds, and finches. It particular he was startled by the amount of VARIATION between the populations that lived on different islands.
300
Even though all species have adaptations suited for their environment, under the theory of evolution, what do they have in common with one and another?
A Common Ancestor

What is the difference between a homologous structure and an analogous structure. Give examples, please
Homologous structures are body parts of organisms that are similar in structure and position but different in function. Such a bird, cat, frog, and human arms Analogous structures perform a similar function but differ in structure (Bird, Bat, and insect wings)
300
Which is the source of variations in a population of organisms. A.) Changes in environment B.) Changes in genes C.) The interaction of genes with an environment D.) the interaction of individuals with an enviroment
B.) Changes in genes

What can lead to extinction events? Be able to describe and give two examples of different ways this can come about.
Sudden Change or Gradual change. Environments can change quickly like a meteorite impact like the dinosaurs. Or it can happen gradually, like sea level change or tectonic plate movement
400
Why is variation important to the process of natural selection? Describe it, please
Variation is important because it makes a population better suited to the particular environment they live in. Variation can lead to adaptation over time within this population.

How do camouflage and mimicry differ?
Camouflage is an adaptation that enables a species to blend in with its environment Mimicry is an adaptation of one species to resemble that of another species. One is adapted to the surroundings while one is made to look like another species all together.

How is comparative anatomy used to relate living species together?
Comparative anatomy compares the similarities and differences among structures of living species to see how closely related they are.
400
What is the eon, era and period humans live in?
Phanerozoic, Cenozoic, and Quaternary

Describe how scientists date sedimentary rock and fossils they may find buried within them?
Scientists use relative age dating (law of superposition) to date sedimentary rock. They figure that the layers on top are much younger than the layers below. They also you absolute age dating (radioactive decay) to date the igneous rock layers to give better estimates a layers above and below it.

Give the definition of Natural Selection as Charles Darwin described it. Give an example
Natural selection is the process by which populations of organisms with variations that help them survive their environments live longer, compete better and reproduce more than those that do not have that variation. Finches with different beaks can eat different kinds of seeds which make them better fit for their environment
500
What is the difference between artificial selection and natural selection.
Artificial selection breeds organisms for desired/selected traits which become more abundant over time. Natural selection has variations in the population which are randomly selected by the influence of the environment.

Summarize Darwin's theory of evolution by natural selection using the Galapagos finches as an example
Finches have different beak variations to eating specific seeds in their environment. Over time, on the Galapagos, these variations made some beaks more beneficial depending on the environment of the particular island. As such, the beneficial beaks became more abundant in the population and led to different adaptations depending on the finch and the seed they were eating. Thus different species of finches evolved due to the selective eating pressure of the seeds and competition with others as well.
