How do the formation of the ozone layer permit organisms to colonize land?

The formation of the ozone layer, which absorbs harmful ultraviolet (UV) radiation from the sun, was crucial for enabling organisms to colonize land. By filtering out much of this radiation, the ozone layer created a more hospitable environment, protecting terrestrial life forms from DNA damage and other harmful effects of UV exposure. This allowed plants and animals to thrive and evolve in terrestrial ecosystems, ultimately leading to the rich diversity of life we see today on land.
