Final answer:
H. habilis lived at the same time as A. boisei and H. erectus at Olduvai Gorge, a paleoanthropological site in Tanzania.
Step-by-step explanation:
At Olduvai Gorge, it is true that H. habilis lived at the same time as A. boisei and H. erectus. Olduvai Gorge is a paleoanthropological site in Tanzania where important fossil discoveries have been made. The presence of these three species in the same region suggests that they coexisted during a specific period in human evolution.
