[Lipitorseffec]

If this guy is not believing that the first human being was Sayyidina Adam عليه السلام and that Hawwa was created from his rib, and that they are the common ancestors of ALL human beings, than yes he is a kafir. Also, you have to clearly define what you mean by "evolution". I mean it is a fact that humans have been changing over time. Sayyidina Adam عليه السلام was sixty cubits tall, but over time human beings have gotten smaller. Sayyidina Nuh عليه السلام lived to the age of nine hundred and fifty years, but over time human being age span decreased. If you want to call this as "evolution" that is fine, as long as you believe these facts there is no problem.
