Write a 2000 word article...

Job ID: 35081152

Budget: $250 – $750 USD

I need a 2000 word article written in English that will be optimized for the following keywords which are also the topic/theme of the article:

strange facts about rh negative blood
rh negative blood type origin
alien blood type
rh negative alien
rh negative bloodline
rh negative blood origin

One will have to do a certain amount of research in order to write this article. I don't want some garbage to be written, but it doesn't have to be an academic dissertation either. :)
