True of False: Lamarck hypothesized that traits developed during an organisms lifetime could be passed to its offspring. For example, a parent works out and has big muscles therefore, the child will have big muscles.
True

What is the difference between relative dating and radiometric dating?
Relative dating is an estimate age. Radiometric dating is an exact age.
200
a type of rock formed when layers of sand, silt, clay or mud are deposited from a solution. Also, where most fossils are found.
Sedimentary rock

Darwin proved that ______________ means that organisms with traits best suited to their environment are more likely to survive and reproduce
Natural Selection
200
When organisms fight for food and living space this is called?
Competition
200
The term for body parts that are similar in origin and structure
Homologous Structures

Whats the difference between variation and adaptation?
Variation is a difference in an individual that makes it different than the rest of the species. An adaptation is a variation that makes an organism better suited for its environment
300
This makes an individual species different from other members of that species
Variation

What is the name of the ship that Darwin sailed on?
HMS Beagle
300
Explain how a new species can form
Helpful variations (like the peppered moths) and Geographic isolation (like the little Key Deer in Florida)
300
A rapid change that occurs when a mutation of a few genes results in a species suddenly changing to a new species
Punctuated Equilibrium
300
Whats the difference between fossils that are found on the top compared to the ones found on the bottom of sedimentary rock?
The top fossils are younger than those found on the bottom
400
Any variation that makes an organism better suited for its environment
Adaptation
400
Where did Darwin study many plants and animals?
Galapagos Islands
400
Give an example of a helpful variation.
Camouflage, beak shapes, wings, ear size, etc.
400
Structures that do not seem to have a function
Vestigial Structures

Whats the difference between fitness and differential reproduction?
Fitness is an organism's ability to survive and produce offspring. Differential reproductions is the fact that not all individuals get to reproduce to their full potential.
500
A slow, ongoing process by which one species changes to a new species
Gradualism
500
In what year did Darwin sail to the Galapagos Islands?
1831

What does it mean if a species goes extinct? Give an example.
Extinction means there are no living organisms of a certain species left on Earth. Examples: Dinosaurs, Dodo bird, Woolly Mammoth, etc.
500
A small group of organisms that share similar characteristics and can reproduce among themselves to produce fertile offspring
Species

What is the difference between the rock pocket mice? Explain what happened and why some are better suited for the environment
A mutation in the DNA led to a dark mouse being born in a population of light brown mice. The mutation allows the dark mouse to be better suited to the environment to blend into the dark rocks, while the brown mice continue to blend in to the desert.
