[QUOTE="BSK, post: 5785931, member: 17"] Neither. White-tailed deer are so genetically diverse, mother-son, father-daughter breeding happens all the time, and no problems arise. Inbreeding is such a problem in humans because we have so little genetic diversity. Our closest genetic cousin is the chimpanzee. We share 98.8% of our genetic code with them. However, there is more genetic diversity within a single chimpanzee social group than there is between all the Humans on the planet. Genetic research suggests humans have so little genetic variation because we have experienced so many "founder events," events that knocked the local human population down to extremely low levels. These population levels were so low that when the population rebound, all people in the region are the descendants of just a few founder event survivors, hence very little genetic diversity. These founder events happen fairly frequently (in a geologic timeframe) and happen at different times in different regions. As an example, in some parts of Europe, the Black Death could be considered a founder event. Europe and Asia-wide, the Black Death probably "only" killed 30-50% of the human population, but in localized pockets, the Black Death killed 80+% of people. Imagine a town of several thousand people that experienced an 85% fatality rate. The people who repopulated the town would all be very closely related because there were so few survivors. [/QUOTE]
