Ecology Analysis

        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
