  To make the answer short: probably yes. Evolution is a dynamic process that is still active right now! But it is a bit more complicated than that: even if a body part is not needed anymore, it it may stay for a long time if it does not require extra physiological effort to be made and maintained, and if it is not a handicap for the bearer. Evolution is not a conscious Being. It is a complex process that does not produce the best organisms possible, but more simply organisms that function well enough to survive and breed successfully in a particular environment at one particular time in the History of Life. So things can remain the same for a long time if they don’t disturb the good function of the organism, even if they are not particularly needed!
