Three models of human evolution are - The ‘Out of Africa' (Replacement), ‘Multiregional Evolution' (Continuity), and ‘Assimilation' model.
The 'out of Africa' model - all living humans descend from a population first appeared in Africa and subsequently distributed to all continents across the globe.
Multiregional evolution model - The hominin population has maintained extensive social and biological ties across Eurasia and Africa. Isolation of hominin populations created regional variation in behaviour and biology.
Assimilation model - combine these two models.African origin with varying degrees of integration through interbreeding with existing populations spread from their origin place.
