Science explains what draws humans to the sea

Our ancient ancestors came out of the water and evolved from swimming to crawling to walking. Human fetuses still have “gill-slit” structures in their early stages of development, and we spend our first nine months of life immersed in the “watery” environment of our mother’s womb. When we’re born, our bodies are approximately 78 percent water. As we age, that number drops to below 60 percent — but the brain continues to be made of 80 percent water. The human body as a whole is almost the same density as water, which allows us to float. In its mineral composition, the water in our cells is comparable to that found in the sea.1
