What is suggested by the fossils found in Dmanisi, Georgia regarding the spread of H. erectus?

The fossils found in Dmanisi, Georgia, provide critical evidence regarding the dispersal of Homo erectus from Africa into Eurasia, dating back to approximately 1.8 million years ago. This indicates that H. erectus was able to migrate relatively quickly into new territories. The Dmanisi site contains some of the oldest hominin remains outside of Africa, suggesting that this species was among the first to venture beyond the continent.

The rapid spread into Eurasia is supported by the diversity of the Dmanisi fossils, which exhibit morphological variations and adaptations indicating that H. erectus was capable of thriving in diverse environments. This adaptability is reflected in their ability to occupy a range of ecological niches as they moved further from their origin in Africa.

In contrast, options that suggest a slow migration or limited adaptability do not align with the evidence provided by the Dmanisi findings. The fossils demonstrate that H. erectus could withstand the challenges of new environments, contradicting any notions of a sluggish or ineffective spread into Eurasia. Overall, the findings at Dmanisi highlight the capacity of H. erectus to not only leave Africa but also quickly establish itself in diverse habitats across Eurasia.
