We don't
know anything to be evolution. There's a
theory, by Charles Darwin, that some have accepted to be the most accurate process of evolution but something that scientists are always researching. Just wanted to clarify that.
To answer your question: Yes, the Qur'an does speak of a evolutionary process. As we're gaining more knowledge as human through the science we're understanding the scripture more and more.
