How the rise of continents may have set the stage for life on Earth

Phys · · 433 words · By David Bidwell

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.

“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.”
SINGLE SOURCE
The provided web search results for this specific claim are generic AI study tools and do not contain the actual content of the study or the journal Terra Nova. However, claim 2 contains a snippet mentioning 'How the rise of continents may have set the stage for life on Earth', which aligns with the claim, but this appears to be a single reporting instance in the provided evidence.
