But when did this prehistoric parade of evolution begin?
Evidence of microbes has been discovered dating back3.7 billion years.

The first animals showed up around 800 million years ago with specialized cells and DNA.
Around 580 million years ago, life forms diversified even more across the waters of the oceans.
But could complex life have made an appearance in our planet’s history earlier than expected?

While a basic single-celled organism, this prehistoric life would have existed around 2.1 billion years ago.
We see the same process as in the Cambrian period, 635 million years agoit helps back that up.
It helps us understand ultimately where we have all come from.
Some scientists are skeptical that complex life, in fact, emerged despite the unique conditions that existed.
A team of researchers believe they have discovered evidence that complex life evolved 2.1 billion years ago.
