No, animals, plants, and also people evolve. For example, penguins used to be "flying" birds, but they moved to colder places and adapted to the new environment by gradually evolving to better suit the cold. But I don't believe in Charles Darwin's theory.
Draw a bell curve. Now draw two vertical parallel lines through the bell curve. Imagine some event eliminating what falls between the two lines. What falls outside the two lines is allowed to reproduce. What falls between the lines, does not. Therefore, the future individuals express the traits of the survivors and not the others. That is evolution. When someone jumps to a conclusion that this is proof that there is no God, is called a fallacy.
