The Neanderthal phase was a theory at one point.

Apart from Teshik Tash in Uzbekistan (Central Asia) there is a wide spread
Asian Mousterian and N remains in southern Siberia.

Modern analogies (e.g. the peopling of the Americas) are not thought to be very
good at describing what happened in prehistory.
The theory you state is either the Afro-European Sapiens Model (with migration)
or the Assimilation Model (without migration).

These date to about 33 ka.
