Our hypothesis is that early planktonic algae developed ultraviolet protective screens similar to those found in marine invertebrates (for example see Cheng et al. (1978)). We present here evidence that some algae with ultraviolet screens are still extant. In present day environments of intense sunlight, these ultraviolet screens may yet today be a selective advantage for primitive photosynthetic organisms.
