Document Summary

Group of hypotheses that have been supported with repeated testing. Looking at the why or a larger question where smaller pieces can and will be changed as new evidence comes in. Smaller objects attracted to a larger object. Einstein"s theory of relativity - how gravity works. Every generation is slightly different than the one before. All life on earth descended through single celled organisms through evolution. Offspring are similar, but not identical to parents. Every batch of offspring contains a natural variation - key to evolution. Change (divergence of character from the parent) Theory: more organisms are born than can survive. Genetic variations that ensure you aren"t eaten or can get enough food to reproduce are passed on. Ability of organisms of one generation to obtain representation in the next generation. You survive better if you"re not eaten. Molting fur too late - dying out. Most of the predators are sight and sound hunters.
