Geologic Time
The largest measure of geologic time?
Eon
This is the geographic location where Darwin studied birds and tortoises.
Galapagos Islands
This is the name of a mold that has been filled in with the same shape as the original organism.
Cast
This happens when organisms evolve during short bursts of rapid change.
Punctuated Equilibria
These are the three types of adaptations a species might develop over time.
Structural, behavioral, functional
This is the name of the chart that divides Earth's history into different time units.
Geologic Time Scale
Though he was not the first to come up with the idea, history has credited him with this theory.
Evolution
This is what it is called when fossil remains turn to stone because minerals slowly replace the original substance.
Mineralization
This helps an organism avoid being eaten by blending into the environment.
Camouflage
This is the general term given to the study of similarities and differences among structures of living species.
Comparative Anatomy
This is what the law of superposition states.
That old rocks are under new rocks.
This is what Darwin called the slight differences among members of a species.
Variations
An organism was more likely to become a fossil if it lived near this.
Water
The ability of fire ants to band together and survive a flood is an example of this type of adaptation.
Behavioral
This is the type of comparative anatomy that results in humans, cats, frogs, bats, and birds all having some form of arm or forelimb though each uses them differently.
Homologous
This is how old something is compared to something else.
Relative age
This is the name of the process by which populations of organisms with variations that help them survive live longer, compete better, and reproduce more.
Natural Selection
This is the name for dead organisms that become compressed over time leaving only an outline.
Carbonization
The fact that caterpillars resemble snakes allows them to avoid being eaten by predators. This is an example of...
Mimicry
This is a form of comparative anatomy in which birds and flies both have wings that differ structurally.
Analogous
16 Days
This is the characteristic of a species that enables the species to survive in its environment.
Adaptation
This is the point in time in the past when living species separated from their common ancestor.
Divergence
This is when humans cross breed organisms for desired traits. (ex: crossing disease resistant corn with sweet corn)
Selective breeding
This is the general term for body parts that have lost their original function through evolution, such as the human appendix or wisdom teeth.
