Fossil Evidence
A chart that divides earth's history into different time units
Geologic Time Scale
A person who studies plants and animals through observations.
naturalist
In natural selection, this is the agent that "selects" for or against traits of an organism. This also chooses which organisms will be successful in the habitat.
What is the environment?
What is an adaption that enables a species to blend in with its environment? What type of adaptation is this?
Camouflage
Structural
A scientist who studies the science of the development of embryos from fertilization to birth
Embryologist
This is made up of all the fossils ever discovered on earth.
Fossil Record
When the last organism in a species dies what is that called
Extinction
Any kind of inherited trait that improves an organism's chances of survival and reproduction in a given environment.
What is an adaptation?
The resemblance of one species to another species to increase survival is .....
Mimicry
These parts of an embryo is evidence of a common ancestor among vertebrate animals
Pharyngeal pouch
backbone
A less accurate way to measure the ages of rocks based on their position in a rock layer.
Relative Age Dating
What is bipedalism
When an organisms walks with two legs.
This can be inferred about a particular time period if fossils show a high rate of extinction
What is a large amount of environmental change
Giraffes have developed long necks to eat from the top of tress this is an example of what type of adaptation.
Structural Adaptions.
adaptations that involve chemical changes in the body system
functional behavior
What does the law of "Super Position" say about rocks and fossils
It states that rocks on the bottom are older and rocks on top are younger.
This person traveled to the Galapagos Islands in the early 1900's and developed the theory of evolution?
Charles Darwin

This type of adaption could be seen in animals that migrate in the fall.
Behavioral Adaption
Disappearance of a type of fossil in the fossil record is evidence of
Extinction
A more precise method of finding the ages of rocks and fossils by measuring the decay of isotopes in the rocks.
What is absolute dating?
A slight difference in an inherited trait of an individual member of a species
Variation
The random appearance of a new trait in an organism.
What is a mutation?
The oryx has evolved its body to only have to drink water once every few weeks. This shows what type of adaption.
Functional Adaptation
