Rock pools – is this where life began?

When gazing into a rock pool, spotting the many different organisms in this ecosystem, it’s worth pondering life’s origins born of this environment of extremes.

A hint at our own aquatic past is suggested in a correlation between the human menstrual cycle and the lunar cycle. Many aquatic species follow the same lunar cycles influence on the tides for reproduction.
