Our genome is littered with scraps of DNA, termed âjunkâ DNAs, that serve no apparent purpose. Junk DNAs make up as much as 98.5% of our genome. Scientists believe that some junk DNAs came into existence millions of years ago, when viruses inserted their DNA into that of the human host. There is emerging evidence that suggests that these bits of microbial DNAs may alter our functional genes, impacting our body physiology and behavior.We have been invaded by âbody snatchersâ and they are part of us! We could postulate that we are carrying a large number of DNAs that serve only the DNAs, and we are just a small part of the big picture! There is ample scientific evidence to suggest that, even today, free-living microbes are still manipulating our behaviour and our life at large. They are thriving on our wet skin, in our mouth, and in our intestinal and vaginal tracts. We are perhaps not quite what we think we are.This thought-provoking and inspiring book offers many answers, while at the same time raising many questions for future research.
