In addition to the text, I really like your pictures. Just quick comment regarding your section on population. The example of using antibiotic resistance on bacterial populations is a case of "selection" rather than "genetic drift". The process of genetic drift is random, while selection is not. It is not "random" that only antibiotic resistant bacteria survives after a certain amount of time. What is due to chance (i.e. genetic drift) and what has happened for a reason (i.e. selection) is the biggest challenge in studying human genetic diversity (see HapMap project). Anyways great post, keep up the good work ! http://en.wikipedia.org/wiki/Genetic_drift Awesome post Lauren. In addition to the text, I really like your pictures.
