The original origin of Homo Sapiens is not exactly known yet, but there are two main hypothesis that stand out when talking about the subject.
Multiregional Hypothesis: This hypothesis states that all Homo Sapiens evolved from earlier populations in Asia, Europe, and Africa, at the same time. According to this hypothesis, certain structural traits have been passed down from Homo Erectus and other transitional forms of Homo Erectus in Europe and Africa. This means that multiple different species, like Homo Erectus and Homo Heidelbergensis, evolved into Homo Sapiens around the same time period.
Out of Africa Hypothesis: the other, more popular idea, is the out of Africa Hypothesis. It states that a smaller population of early humans in Africa evolved into Homo Sapiens. These populations would have spread across Asia, Europe, and Africa. Some of the evidence for this hypothesis is that the DNA of every person today that lives outside of Africa has DNA in common with this small group of Homo Sapiens. The research for this hypothesis revealed that the early homo sapiens came no later than 200,000 years ago, which is too young for the mulitregional hypothesis. There is also a molecular resemblance between archaic humans and modern humans.
