Human parasites such as pinworms and tapeworms are fairly advanced and complex multi-cellular animals that possess digestive, circulatory, nervous, excretory, and reproductive systems.
Do you believe that pinworms have existed as long as humans have existed or do you believe that they developed or evolved at some later time?
