Large-scale homogenization of the entire human genome could present some problems, if this trend were to continue into our evolutionary future…as it is likely to do. Most evident is the degradation of genetic variation, which is vital to maintaining the adaptability and survivability of any organism, as per the laws of evolution. For example, decreased genetic variation in the human leukocyte antigen system (HLA) that encodes the major histocompatibility complex (MHC), which together form the backbone of our immune system, would make us more susceptible to diseases, which could potentially
