Index of refraction
|
How much a translucent object refracts light rays passing through it
|
|
|
Spherical gradient lens
|
A sphere-shaped lens. The index of refraction increases smoothly from the surface of the lens to the center
|
|
|
Postulate
|
A declaration of something self-evident; something that can be assumed as the basis for argument
|
|
|
Natural Selection
|
"Evolution by variation and selective retention." Desirable traits cause better survival of individuals and are passed on; non-desirable traits die out.
|
|
|
Morphology
|
An organism's size, shape, and composition
|
|
|
Stabilizing selection
|
Selection in one direction until the disadvantages outweigh advantages.
|
|
|
Trait/character
|
Characteristic of an organism, i.e., seed color.
|
|
|
Species
|
According to Darwin, a dynamic population of individuals. Lowest level of taxonomy.
|
|
|
Essentialism
|
The idea that a changed species was no longer that species (Ernst Mayr).
|
|
|
