To summarize the observed facts of Evolution:
•
Matching of fossils of extinct animals to that of modern animals.
•
Examples of natural selection of species adapting to their surroundings. Survival of the fittest is a
biological mechanism. Birds will occasionally kill their young if they are weak so the surviving ones have
more food. When a Cheetah makes a kill, it’s the prey which runs the slowest which gets killed. This also
explains why 99% of all life which has lived on Earth is now extinct.
•
Examples of artificial selection (Wolves to Dogs)
•
No two individuals are exactly alike.
