Glendale Community College Forces of Evolution Discussion

I’m working on a anthropology writing question and need support to help me learn.

Choose ONE of the prompts below for your initial discussion post: 

Describe a hypothetical scenario of natural selection for a specific species trait.  Be sure to describe each of the key elements (such as how the trait varies in the population, how the traits factors into resource competition, and how the trait frequency changes over multiple generations).  

Describe a hypothetical scenario of the founder effect for a specific species trait where substantial genetic variation is lost (causing a population bottleneck).  Be sure to describe each of the key elements (such as why the founder event occurs, why genetic information is lost, and how the trait frequency changes over multiple generations).  

Describe a hypothetical scenario of gene flow for a specific species trait.  Be sure to describe each of the key elements (such as trait frequency in the two isolated populations prior to one flow occurring, why gene flow occurs, and the consequences of the gene flow in future generations).
