CONFIDENCE IN THE FACT OF EVOLUTION RESTS UPON THREE GREAT CLASSES OF INFORMATION – ACCORDING TO GOULD
SMALL SCALE/ SHORT TERM CHANGES • CHANGES WE CAN SEE DURING A LIFETIME • DIRECTLY OBSERVABLE
BACTERIA RESISTANCE TO ANTIBIOTICS • EX MERSA • METHACILLIN • RESISTANT • STAPHYLOCOCCUS • AUREUS
LARGE SCALE/LONG TERM CHANGES • CHANGES THAT TAKE PLACE OVER TENS OF THOUSANDS, HUNDREDS OF THOUSANDS, MILLIONS, TENS OF MILLIONS, HUNDREDS OF MILLIONS, AND BILLIONS OF YEARS • WE CANNOT POSSIBLE OBSERVE THESE CHANGES, BUT WE CAN INFER THEM FROM THE EVIDENCE
HUMAN VESTIGIAL STRUCTURES • TAILBONE • APPENDIX • EAR WIGGLE • NICTITATING MEMBRANE • WEBBING IN FINGERS AND TOES • WISDOM TEETH • ……….
VESTIGIAL STRUCTURES IN WHALES • Hind limbs • Finger muscles • Diaphragm • Ear canal that leads to no external ear • ….
VESTIGES IN SNAKES • HIPS, LEGS IN PYTHONS, BOAS
EVIDENCE OF HISTORY IN ECOSYSTEMS • COAL IN ANTARCTICA • SEA FOSSILS IN DESERT REGIONS • SEA FOSSILS ON MOUNTAIN TOPS • LAND FOSSILS ON SEA FLOOR • ….. • DUE TO CONTINENTAL DRIFT
