Corals may forego procreation for a year, but a little moonlight has been known to turn them on. “On certain full moons each year, blue waters above reefs turn milky as corals release eggs and sperm in massive outbursts of reproductive activity.” The corals lack eyes to detect the light, “Yet hundreds of coral species somehow time their spawning with the light of the moon.” Several publications have picked up on this theme. The New York Times writes, “[A]t night, just after the full moon, under warm tropic breezes, the corals dissolve in an orgy of reproduction…”

In a similar vein, evidence has emerged of seafood noshing, makeup wearing early humans. An article in the journal Nature indicates that early humans share some characteristics with modern ones. Items including advanced tools and pigments were found on the southern African coast dating from 164,000 years ago. Use of pigments suggest to one of the scientists studying the trove that the users “were people with symbolic capacity. And the ability to think symbolically is the foundation of the ability to have language.”

Assorted remains of shellfish found with the other items present the “very first evidence of humans eating seafood.” Seafood is one of the last major food resources that humans learned to exploit before the domestication of plants and animals. However, it was previously believed to have happened long after the evidence in this find indicates.
