We believe that instead of using vines to pull themselves up into the forest canopy, our earliest ancestors may have instead used the kelp stipes to pull themselves down into the underwater kelp forests.
Using these rubbery stipes, the first people could have easily gathered from the rich harvest on the seafloor. The kelp forests are some of the most nutrient-rich waters on the planet, reaching up to 65 times more nutritious then the ocean average. The kelp itself is one of the fastest growing plants on earth, and is highly nutritious and easy to cook. The kelp forests also provide a natural barrier against the waves of the open ocean, and great white sharks seldom hunt in the forest.
