If you are wanting to say that the implication is that we do NOT share common ancestry with primates, then you read it correctly. Not every human being has the same DNA gene code, and even when we go back to our ancestors, is it incredibly small. Looking at an article online just now, and it shows that if we go back to a 7th generation grandparent, our genetic relationship to this ancestor is only 0.78%, and the further we go down the line, the less it gets, and (I am only guessing at this stage) I am sure it cannot get to 0%. Here is the relatively small article:

This is simply evolution in progress where the biological processes are, over many generations, mixing up various DNA sequences, which are mixed with other DNA sequences from other ancestors, which gets us to who we are today. For example, unfortunately, I am 6ft 2 inches tall, I have a brother who is 5feet 10. My mother was only 5ft tall and father 5ft 6inches tall. So, looking back at my ancestry, I am finding it very difficult to see where I could have got my genes from. Most of my cousins are shorter than me, and a couple shorter than my father. My grandad was a couple of inches shorter than my father, my great-grandfather was the same height as my grandfather. My G-grandfather had 8 children and I have seen a family photo from 1911 and there is nothing there to suggest that anyone was tall.
