Possibly the currently favoured view is that anatomically modern humans didn't evolve in one location, but evolved in a structure population that spanned Africa (and perhaps the Middle East):
We challenge the view that our species, Homo sapiens, evolved within a
single population and/or region of Africa. The chronology and physical
diversity of Pleistocene human fossils suggest that morphologically
varied populations pertaining to the H. sapiens clade lived throughout
Africa. Similarly, the African archaeological record demonstrates the
polycentric origin and persistence of regionally distinct Pleistocene
material culture in a variety of paleoecological settings. Genetic
studies also indicate that present-day population structure within
Africa extends to deep times, paralleling a paleoenvironmental record
of shifting and fractured habitable zones. We argue that these fields
support an emerging view of a highly structured African prehistory
that should be considered in human evolutionary inferences, prompting
new interpretations, questions, and interdisciplinary research
