A few kids with big rocks could "hunt and gather" the meat of a 300-kg sea turtle. Paleohumans had no need for the sharp canine-teeth that non-human primates have. Instead, they needed friendly teeth, to smile with neighbors as they shared and ate their chewy food. No fire, no weapons, no big muscles. Just paleohuman blubber for floating in the water, where they could eat their turtle meat without getting sand in their mouths.
