Emacs Lisp was mostly patterned after MACLISP. It didn't have these
functions, either. I think they were introduced in ZetaLisp or NIL, and
Common Lisp inherited them from these dialects. MACLISP didn't have as
many of these higher-level functions as Common Lisp does. Elisp mostly
added on stuff related specifically to editing and buffer management,
but not much to do with basic data types like lists.
For a long time Elisp didn't even have floating point numbers!
