Final answer:

Fully modern human traits first appear in fossils dating back to around 200,000 years ago, providing evidence of anatomically modern humans in Africa with distinct characteristics like rounded skulls and developed chins.

Step-by-step explanation:

The question seeks to identify the time period when fossils with fully modern human traits first appeared. Fossils of anatomically modern humans, or Homo sapiens sapiens, with the physical characteristics of our species were present in Africa around 200,000 years ago.
