I have been wondering of the inherited stuffs since age old times!

Do you get any of the stuffs that never existed during the earlier times but is the result of latest of few years only. I don't feel so but the surprising fact is that many of those stuffs are coming out more openly to the surface than ever before. So can you list few of those stuffs which were already there but have been publicized as though these are newly emerged theories propagated by the later government? This is going to be interesting as many of us still believed of the tales of fantasies led to the brain washed to the then existed generations which are now reflecting on today's society.
