This contradicts the open savanna theory for the origin of bipedalism, which states that humans learned to walk upright as climates became drier and environments became more open and early ancestors—but we keep learning more! D., Asfaw, B., Beyene, Y., Hailie-Selassie, Y., Lovejoy, C. A partial skeleton of a female, known as "Ardi", combines human and other primate traits.
The research involves artifactual and nonartifactual data.
Adherents to this model look at early material and try to trace continuity in morphology from those early populations to later populations in the same geographic area.
In this model, there are paralleled changes in all penecontemporary populations, with enough genetic migration to maintain close species bonds, while still allowing the suite of racial features we see today.) did not contribute a significant amount of genetic material to later populations that led to modern humans (some claim no genetic ancestry to these groups and their descendants at all, a “strict” replacement model).
