    You need to make your question more clear, as I cannot understand what you are asking.

    when before stone age,the human beings are like as a gorilla. i mean their appearance , using four legs to move ....etc... but now we have got changes . we have a big brain, use two legs to walk . so is it relating the changes of DNA,or others?

    Changes (mutations) in the DNA sequences will give rise to the differences you observe between two species.
