Scientists use it to describe how organisms have changed over time.
Fossils, D.N.A., vestigial organs or structure, same structure diffrent function.
By examining fossils and by determining their relative and absolute ages, scientists have collected evidence that supports the theory that species changed over time.
Modern scientists now use genetics to help explain the theory of natural selections.

Scientists organize nature into systems to make it easier to understand.
scientists makes models so when they do the acual project they can see what to do from the scale size to the acual figure.to do scale testingscientists use models to help them understand what they are working on
Studying the earth helps scientists to understand other planets since the earth is part of the solar system. Scientists use the features of the earth to compare them with what other planets hold.
