species has the exact same reactions to that disease, meaning that it could potentially wipe out the entire population. This could even occur in a relatively short period of time. Say everyone in your history class all had the same reaction to the common cold, and that reaction was fatal. If one person caught it...well, everyone would die. However because humans have good gene diveristy our resistance to a given disease differs greatly from individual to individual. Thus preventing the spread of epidemics as easily. (For the most part.) LAstly take the example of German Shepards. They have been interbred for so long that the small hip problem that was probably present in only a few of the dogs then, is now a recurring problem in most German Shepards alive today.

Gene Pool Diviersity
Gene Pool Diversity is essential to a healthy ecosystem for the following reasons. Firstly, a gene is a structure in an organisms cell that carries the hereditary information. Therefore if there is no diversity in organisms genes in a given area, and an epidemic strikes, every single one of that
