Question restatement: Which of the following is a prediction of the multiregional models for the origins of modern humans?

Option A: 'a single evolving lineage of H. sapiens in each region of the Old World' — This option suggests a completely isolated, region-by-region evolution with no continuity across regions. In contrast, multiregional theories emphasize long-standing regional continuity with gene flow among populations, not a single isolated lineage per region. Therefore, this statement misrepresents the core idea, making it incorrect.

Option B: 'regional H. erectus characteristics appearing in local H. sapiens populations' — Multiregional models predict that modern humans arise in multiple regions with continued gene flow among regional populations. A key corollary is that archaic traits (from regional H. erectus populations) can persist in local modern human populations. So this option captures a plausible prediction of regional continuity and trait retention, marking it as a correct interpretation within the multiregional framework.

Option C: 'gene flow between H. neandertalensis and H. sapiens populations' — Another central component of multiregional thinking is ongoing interpopulation exchange, including gene flow between archaic groups like Neanderthals and regional Homo sapiens. This interbreeding aligns with the idea of connected, intermingling populations across regions, making this statement consistent with multiregional predictions and thus correct.

Option D: 'all of these' — While options B and C align with multiregional predictions, option A does not. Since the claim of a single evolving lineage per region is not part of multiregional theory, the aggregate claim 'all of these' is inaccurate. Therefore, this option is not supported by the multiregional view.

Rationale summary: Options B and C reflect key multiregional predictions about trait retention across regions and inter-population gene flow, whereas A contradicts the central premise of regional continuity with admixture. D falsely combines an incorrect statement with correct ones, making it unsuitable as the predicted outcome according to multiregional models.
