Were early human beings (about 100 - 200 K years ago) far more promiscuous than we are now?
My hypothesis is "Yes", that is "Early human beings are far more
  promiscuous than we are now". So how i came up this? Cos Human came
  from Chimpanzee right?


No.  


  Also, when human evolved, they started to realized that
  promiscuousness wss not healthy &amp; not good for society


I'm sorry, what ancient society are you claiming cracked down on male promiscuity?
