Genetic diversity not only gives some individuals better chances against diseases but also helps species overcome environmental hurdles like a change in temperature or soil nutrient levels (think venus flytraps).
Humans survive in a different way. We live and learn longer, leaving us more likely to get killed but with the right nurturing from a parent, you should come out with a higher survivability than most animals because you learn to outwit everything else.
