Our species definitely originated in Africa. All the genetics point to this being the case (there is much greater genetic diversity in African populations vs. anywhere else in the world). The question is whether additional significant evolution (and even back flow into Africa) happened after we left Africa. And I think the answer to that question is, yes, it did (as evidenced by the significant admixture with Neanderthals and Denisovans). If you're interested, there's a great episode of The Insight podcast with Milford Wolpoff that discusses a lot of this: https://insitome.libsyn.com/multiregionalism-is-deadlong-live-multiregionalism https://insitome.libsyn.com/multiregionalism-is-deadlong-liv...
