Researchers from Cornell University, New York, believe millions of years of evolution on Earth can help find life on alien worlds.
By looking back at more than 500 million years of the Earth’s plant-life history, we may better understand distant habitable exoplanets.
The emergence of flora on Earth was a crucial element in the processes which transformed the rocky planet into one where life could thrive.
The same processes on exoplanets could be equally responsible for harbouring and sustaining alien life.
