Evolutionary biology concerns only the evolution of the human body, not the soul. Also, natural selection only explains the adaptation of organisms to its environment, not common descent.
It is true that biology textbooks don't mention the human soul. However, science textbooks also don't mention free will and the conscious knowledge of human beings. It is understood that human rationality, the soul, God, and intelligent design are not scientific concepts and don't belong in a biology textbook.
While many writers, even science writers, think natural selection explains the increase in the complexity of life as it evolved from single-celled organisms to chimps, no professional biologist says such a thing. In my opinion, the so-called debate or "controversy" about evolution is pseudo-science and prevents people from believing in the Bible and the Koran.
