The theory that natural selection can, over time, take an organism and transform it into a more specialized species of that organism.
What is Microevolution?
100
Preserved remains of once-living organisms.
What are fossils?
100
The study of the interactions between living and nonliving things.
What is Ecology?
100
A group of interbreeding organisms coexisting together.
What is a Population?
100
A group of populations living and interacting in the same area.
What is a Community?
200
The hypothesis that natural selection can, over eons of time, transform an organism into a completely different kind of organism.
What is Macroevolution?
200
Distinct layers of rock.
What are strata?

300
Structural homology

The name of the ship on which Darwin sailed to the Galapagos islands and other places.
What is the HMS Beagle?
400
The period of time (about 20 million years) during which most major animal phyla appeared, as indicated by the fossil record.

What is Watershed?
500
A brand of evolution that hopes to provide a mechanism by which information can be added to the genetic code of an organism.
What is Neo-Darwinism?
500
This idea attempts to explain away the fact that the fossil record is devoid of any real intermediate links.
What is Punctuated equilibrium?
500
The process by which certain gases trap heat that would otherwise escape the earth and radiate into space.
What is Greenhouse effect?
500
A form of symbiosis in which two or more organisms live in mutually beneficial relationships; it seems to contradict the idea that organisms always battle for survival.
What is Mutualism?
500
