The origin of life on Earth is believed to have been triggered by a fortuitous event, such as lightning striking a primordial soup of amino acids. In fact, life was already thriving on the planet billions of years before the dinosaurs roamed. The oceans were teeming with single-celled organisms, while the soil was home to a diverse array of living creatures. The question remains, however, as to where this life originated and how it evolved over time to give rise to complex, multicellular organisms like humans.
