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
PESTICIDE RESISTANCE
PEPPERED MOTH
BACTERIA RESISTANCE TO ANTIBIOTICS
•
•
•
•
•
EX MERSA
METHACILLIN
RESISTANT
STAPHYLOCOCCUS
AUREUS
ARTIFICIAL SELECTION
TOLERANCE IN PLANTS AND ANIMALS
DANDELION HEIGHT
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
