NCSU Course ZO410 Lecture: 
Evolution and Genetics

I. Charles Darwin

Major concepts

Natural Selection

Adaptiveness

II. Approaches to Determining Adaptive Value of Behavior


        1) Cost-Benefit Analysis

          2) Comparative Approach

-divergent

-convergent

III. Genes and Behavior

- polygenic inheritance

- pleiotrophy

 1) Twin studies

2) Drosophila genetics

3) Hybridization

4) Artificial selection

5) Gene alteration

-transgenic

- gene action

- knockout

IV. Evolution of Behaviors


Selection results in adaptations and speciation

Three major types of natural selection

-stabilizing

-directional

-disruptive

V. Kinship and Selection


"Selfish gene" theory

Kin selection

Inclusive fitness

VI. Calculating a Measure of Heritability


Heritability= ratio of genetic variation to genetic+environmental variation
    -range in value between 0 and 1
