The exact origin of the human race remains a mystery. There are a number of theories surrounding how life on Earth began and how modern day society came about. The reality is that we may never truly know how or where it all started, but that doesn't mean we should give up on finding out.
According to the theory of evolution, humans are descendants of primates, but researchers from Canada’s McMaster University, along with scientists from Germany’s Max Planck Institute believe they have finally solved the mystery.
The researchers attempted to connect the dots by pulling info from studies conducted in various scientific fields from previous studies. They concluded that the most plausible theory is that sometime around 4 billion years ago, life formed as a result of a meteorite smashing into the Earth's water. Landing in the nutrient-rich waters prompted self-replicating RNA molecules to form.
This theory itself isn't new, but there has yet to be sufficient evidence provided that life began in Earth's oceans. The primary reason this hypothesis doesn't hold up is that RNA polymers require wet and dry cycles to form. Oceans do not support those conditions.
On the other hand, surface ponds can provide these conditions as a result of precipitation and evaporation. Based on the research teams calculations, RNA could have formed nearly 4.2 billion years ago. Actual DNA would have formed much later thanks to evolution. If this theory is accurate, there's a good chance that life on Earth began in the water.
