What to know about How the rise of continents may have set the stage for life on Earth

A study published in Terra Nova suggests that the emergence of granite-rich continental crust on early Earth regulated boron levels in the oceans. This geological process may have created the necessary chemical conditions to stabilize the sugars required for the formation of RNA, potentially enabling the origin of life.

What happened

How the rise of continents may have set the stage for life on Earth Robert Egan associate editor Earth's earliest continents may have set the chemical stage for life by regulating boron levels in ancient oceans, a new study in Terra Nova suggests.

Why it matters

Scientists have long proposed that boron helps stabilize the fragile sugars needed to build RNA—the molecule thought to have preceded DNA in early life—making it an essential ingredient in life's origins.

Common ground

But boron operates within a narrow window: too much, and it becomes toxic to biological systems; too little, and it may never have contributed to life getting started.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
