IMO - Obviously an unborn baby has soul, albeit immature, the potential is certainly there.
Our soul comes from our parents, it looks exactly like we do now, except exists on a Spiritual Plane (dreamscape). The soul manifest the physical body.
As We live and experience Reality the soul unfurls, growing and resonating in both This Realm and The Dreamscape (the dreamscape is manifest through sensation of experience/Life/Living in this realm, by acquisition of information through the bodily senses).

So... The Soul is manifesting the body and the body is manifesting The Dreamscape, where the Soul lives.
