b. and remained there until modern humans from Asia displaced them.
c. about 500,000 years ago.
d. but were later displaced by European Neandertals.

c. Several origins in different areas where modern forms evolved from local populations.
d. Separate origins in Africa and Australia with migrations from both these areas to displace all other populations.
