Natural Selection
Introduction
o What are the forces that influenced Evolution?
1- Natural selection.
2- Random genetic drift.
3- Mutation.
4- Population mating structure.
5- Culture.
 Definition: Natural selection is the process whereby organisms better adapted to their
environment tend to survive and produce more offspring.
Main Hypothesis
o Why is it hard for many people to understand Natural selection?
Hypothesis 1
 understanding the mechanism of natural selection requires an acceptance of the
historical fact of evolution.
Hypothesis 2
 most people simply lack formal education in biology and have learned incorrect
versions of evolutionary mechanisms from non-authoritative sources

• kids are incapable of understanding natural selection because they have not yet
  developed the formal reasoning abilities necessary to grasp it
  Key Parts of The Paper (Body)
  o How does Natural selection work?
  a. Variation and Inheritance
  1- Individuals in a population are not identical, they vary in many characteristics
• Do Mutation produce variation?
• Does Mutation have positive or negative effects?
• How does genetic drift affect populations?
  2- Many characteristics are heritable
• How is natural selection related to genetics?
• Which Traits Are the Most Fit?
  b. Overproduction, Limited Population Growth
  1- Populations have potential to increase exponentially
• What is the survival of the fittest?
  2- Populations remain stable after certain size
• What is the role of Adaptation?
  Conclusion
  o Recap what was said
• What is Natural Selection and why is it important
• How does it influence evolution?
• What factors make NS hard to understand
  o How can we make Natural Selection easier to understand?
  1- Teach in in schools from young age
  2- Relate it to things that happen on a daily basis
