Final answer:
The key aspect of leopard predation that potentially facilitated prey theft by hominids is their practice of stashing kills, possibly leaving the prey unattended and vulnerable to being stolen.
Step-by-step explanation:
The aspect of leopard predation that makes their prey much easier to be stolen by hominids is likely related to leopards' habit of stashing prey in trees after hunting. This can lead to a situation where the prey is left unattended, making it easier for hominids such as early humans to steal the kill without having to confront the predator directly. The fact that leopards may hunt and store more food than they can consume immediately could have been exploited by hominids to scavenge for food. Additionally, the skills that hominids developed in tracking and tool use, such as those demonstrated by Hadza hunters, might have facilitated the ability to efficiently locate and retrieve these stolen meals. It is important to note that while this scenario is a speculative assessment of past behaviors based on modern observations and paleontological records, it illustrates the complex interactions in ecosystems involving predators, prey, and humans.
