the action or process of adapting or being adapted.
Adaptation
in biology, classification comprising related organisms that share common characteristics and are capable of interbreeding
species
the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth.
evolution
the remains or impression of a prehistoric organism preserved in petrified form or as a mold or cast in rock.
fossil
history of life as documented by fossils, the remains or imprints of organisms from earlier geological periods preserved in sedimentary rock.
fossil record
a distinguishing characteristic or quality, especially of one’s personal nature
trait
is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits by choosing which typically animal or plant males and females will sexually reproduce and have offspring together.
selective breeding
the process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin and is now believed to be the main process that brings about evolution.
Natural Selection
In population biology and demography, generation time is the average time between two consecutive generations in the lineages of a population.
Generation time
the formation of new and distinct species in the course of evolution.
Speciation
is the science of determining the relative order of past events, without necessarily determining their absolute age
Relative Dating
is the process of determining an age on a specified chronology in archaeology and geology.
Absolute Dating
s a system of chronological dating that classifies geological strata in time. It is used by geologists, paleontologists, and other Earth scientists to describe the timing and relationships of events in geologic history
Geologic Time Scale
is the termination of a kind of organism or of a group of kinds, usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point.
Extinct
a theory explaining the structure of the earth’s crust and many associated phenomena as resulting from the interaction of rigid lithospheric plates which move slowly over the underlying mantle.
Plate Tectonics
