Final answer:
The statement is false; Olduvai Gorge has been the site of numerous important hominin fossil discoveries, which have contributed greatly to our understanding of early human evolution.
Step-by-step explanation:
The statement that no hominin remains have ever been found at Olduvai Gorge is false. Olduvai Gorge is actually one of the most important paleoanthropological sites in the world and has been instrumental in furthering our understanding of early human evolution. Noted anthropologists such as Richard and Mary Leakey have uncovered fossilized remains of various hominid species at Olduvai Gorge, providing evidence that early hominids inhabited the region.
The region has been under excavation since the 1970s, and discoveries there have made significant contributions to our knowledge of human ancestry. For example, it was in the Great Rift Valley, where Olduvai Gorge is located, that the remains of Homo habilis and other early human ancestors were found. These findings show that multiple hominid species, some of which were not direct ancestors of modern humans, coexisted at various times.
