1. What is EVOLUTION?
The idea of evolution is a simple one. Things change.
The process of cars changing over the past 100 years can be thought of as
an evolution in engineering.
When an organism changes over many generations, it might be better suited to live, or
more likely to die.

3. 1. We have common ancestors.
2. We share common traits.
Embryonic development -
before all structural
stages.
10. How does EVOLUTION HAPPEN?
1. Natural Selection – Survival of the fittest
2. Adaptation – Changing their behaviour, body
structure, traits etc.
3. Overproduction of offspring – produce large no: of
children.
11. 1. Natural Selection
Sometimes you've got a skill that helps you survive; sometimes you don't.
If you were a 500 pound bird with little tiny wings and little tiny legs, chances are you
wouldn't move around too well. One day you might run out of food and die. Oh well,
you were just selected for extinction.
