The Six Kingdoms
Animals, Plants, Eubacteria, Archaebacteria, Protists, Fungi.
Fossils
preserved bones or other trace of an ancient skeleton
Homologous structures
Structures that have a common origin but not necessarily a common function
Vestigial Organs
Organs with little/no obvious purpose
Adaptation
evolution of traits that makes the organism better suited for their environment
Diversity of Life
each living thing depends on others for their own existence
Natural Selection
process in nature that results in survivial of the fittest
Survival of the fittest
competition for survival
Fitness
an organism's ability to pass on its genes to its offspring
Artificial Selection
slective breeding, where the breeding of organisms create offspring with desirable characteristics
common decent
species have descended from common ancestors
mutation
alteration in a cell's genetic information
reproductive isolation
seperation of different species that cannot be inbreeded
gene pool
alleles of all genes of the members of a population that interbreed
genetic drift
random change in allele frequency

alleles of all genes of the members of a population that interbreed
genetic drift
random change in allele frequency
speciation
formation of new species brought about by genetic change that prevent breeding new different groups
gradualism
theory that evolution occurs slowly and steadily over long periods of time
Puncuated Equilibrium
pattern of long periods of stability that are interrupted by episodes of rapid change
adaptive radiation
pattern of evolution, where selection/adaptation lead to a new form of species in a short period of time
convergent evolution
when unrelated species independently form similar characteristics when adapting to similar environments
Analgous Structure
similar: appearence/function

dissimilar: anatomical development/origin
Biodiversity
variety of:

organisms, genetic information, and environments they live in
Economic Diversity
variety of:

habitats, living communities, and ecological processes
species diversity
number/variety of different life form
Genetic Diversity
variety of:

different genetic material
Molecular Clock
theory that mutations in DNA occur at a constant rate
