Did life shape Earth's evolution?

And Life Created Continents...

Life on Earth may have driven the evolution of the planet itself.

The appearance of ancient photosynthesising microbes 3.8 billion
years ago may have provided the chemical energy to create the
Earth's continents. The theory, put forward by a team of Danish
geologists, would solve the puzzle of why the Earth's continental
crust appeared when it did, and explain the presence of granite, a
rock unique to our planet...
