Why Do Most Paleoanthropologists Agree That Several Fossil Forms, Dating

Question

Examlex · Accepted Answer

The Answer is Most paleoanthropologists agree that several fossil forms dating back to around 100,000 years ago should be included as fully modern humans (Homo sapiens) due to a combination of anatomical, genetic, and behavioral evidence that aligns these fossils with our own species.

Anatomical Evidence:
The fossil record from this period shows individuals with skeletal features that are within the range of variation seen in contemporary human populations. These features include a rounded skull with a vertical forehead, a reduced brow ridge, a smaller and less prognathic (projecting) face, a chin (mental eminence), and lighter skeletal build compared to earlier hominins. The cranial capacity of these fossils is also within the range of modern humans, indicating similar brain size and structure.

Genetic Evidence:
Advances in ancient DNA technology have allowed scientists to extract and analyze genetic material from some of these fossils. The genetic evidence supports the anatomical findings, showing a close relationship between these ancient individuals and present-day humans. The genetic continuity suggests that these individuals belong to our species and contribute to the genetic diversity of modern Homo sapiens.

Behavioral Evidence:
Archaeological sites dating back to around 100,000 years ago show evidence of behavior that is typically associated with modern humans. This includes the use of advanced tools, evidence of symbolic thought (such as personal ornaments and art), the use of pigments, and the development of complex social structures. These behaviors suggest a level of cognitive and cultural development that is consistent with what we see in modern humans.

Overall, the combination of anatomical similarities, genetic continuity, and advanced behaviors leads most paleoanthropologists to conclude that these fossil forms represent early members of our own species, Homo sapiens. The inclusion of these fossils within our species helps to trace the evolution and dispersal of modern humans across the globe.
