Natural Selection
Darwin Proposed That
Natural Selection Or
Survival of the Fittest
Causes
Macro-Evolution.
Think Critically:
Does Information Need To
Be Added To The DNA In
Order To Have a More
Complex Organism?
Think Critically:
What Is the Driving Force
Behind
Natural Selection?
Name Some Causes of
Natural Selection.
.
The Driving Force Behind
Natural Selection Is Random
Chance Events Such As
Weather, Food Supply,
Predators, Shelter, Geological
Events, etc.
Think Critically?
Can Natural Selection
Add Information To
The DNA?
Natural Selection Occurs Only
On Living Organisms So Hasn’t
the Information Content Of the
Organism Already Been
Determined At the Time Of
Origination? How Can It Affect
the Genetic Information In That
Organism’s DNA?
Think Critically:
What Kind Of
Evolution Does
Natural Selection
Affect?
Natural Selection CANNOT
Add Information To The
DNA So It CANNOT Be A
Factor in
Macro-Evolution
But CAN And DOES Cause
MICRO-EVOLUTION.
An Example of Micro-Evolution
