Depends on the religion. Catholics and other "orthodox" religions (and orthodox branches of others) say the same: Our doctrine is the One True Doctrine. Others, including many forms of American protestanism, some Episcopalian, etc. allow a broader personal interpretation within guidelines.
Can one be a Biblican Monotheist and/or a Christian and be a Evolutionst? Sure -- even the Catholic Church allows for alternative interpretations of parts of Genesis and some parts of the Old Testament. For that matter a lot of the Bible is still being interpreted by the Catholic Church -- that's why they have Jesuits.
