The idea that organisms best suited (most fit) to their environment are more likely to survive is calledNATURAL SELECTION
Variations (differences) in populations can add....NEW SPECIES
Change in inherited charactersitics or change in hereditary features over time is calledEVOLUTION
Organisms that are similiar (the same) and can successfully reproduce called...SPECIES
A difference in an inherited trait of an organism that may lead to a new species is called aVARIATION
A model of RAPID EVOLUTION isPUNCTUATED EQUILIBRIUM
Model of evolution showing SLOW CHANGE over time isGRADUALISM
Variations result fromPERMANENT MUTATIONS
Any variation that makes an individual better suited to survive (such as a white rabbit in a snowy habitat is calledADAPTATION
Theory of Evolution by Natural Selection is theTHEORY OF EVOLUTION by DARWIN
