The changes that occur during a star ’s life are called stellar evolution. The mass of a star determines the ultimate fate of a star. Stars that are more massive burn their fuel quicker and lead shorter lives. Because stars shine‚ they must change. The energy they lose by emitting light must come from the matter of which the star is made. This will lead to a change in its composition. Stars are formed from the material between stars‚ shine until they exhaust their fuel‚ and then die a predictable

The giraffe is taller than all other mammals‚ can feed where no others can‚ and therefore has a distinct advantage. It seems compelling

ANATOMICAL EVIDENCE OF EVOLUTION In our studies of the anatomy and development of animals we have discovered that many living creatures that look quite different on the surface have similarities underneath their skin that suggest that they are related to each other. This is evidence that living creatures have evolved‚ or gradually changed over time.
