Complex began to develop earlier, and over a longer span of time, than previously believed.

Nee findings indicate that complex organisms evolved long before there were substantial levels of in the , something which had previously been considered a prerequisite to the of complex life.

The is approximately 4.5 billion years old, with the first life forms appearing over 4 billion years ago.

These organisms consisted of two groups – and the distinct but related , collectively known as .

Prokaryotes were the only form of life on earth for hundreds of millions of years, until more complex eukaryotic cells including organisms such as , , and evolved.
