Drilling into trends in genetics, epigenetics of aging, longevity

Since the dawn of civilization people were searching for clues to longevity and trying to extend human lifespan. But only in the past two decades with the advances in genetic sequencing, epigenetic analysis, and increased government investments the area experienced rapid expansion in the knowledge base, allowing scientists to develop comprehensive models and theories of aging. And while there is still much disagreement among scientists, the evolutionary theories are dominating the field. These theories predicted existence of certain genes that provide selective advantage early in life with adverse effects on lifespan later in life or longevity insurance genes. Indeed, the study of human and animal genetics is gradually identifying new genes that increase lifespan when overexpressed or mutated -- gerontogenes. Furthermore, genetic and epigenetic mechanisms are being identified that have positive effects on longevity >> ScienceDaily 28.03.2014
