The ability of humans to find safe shelters and their lesser likelihood of being prey gives them an advantage over gorillas in terms of sleeping hours. Gorillas have to spend more time sleeping because they are more vulnerable to predators, while humans have developed the ability to find safe places to sleep and have also become better at defending themselves from predators. The other options do not provide a satisfactory explanation for the observed discrepancy.
