Ancient algal defenses against UV may have helped plants conquer land
A study reveals that ancient algae developed advanced mechanisms to protect against UV radiation, which may have enabled early plants to transition from water to land. Researchers analyzed a relative of the first land plants and found a complex defense system that helped them survive intense sunlight. This discovery provides insight into how plants adapted to life on land over 500 million years ago.
Scientists studied an ancient alga and found it had defenses against UV radiation, which may have helped early plants move onto land.
Understanding these defenses helps explain how life transitioned from water to land, a key step in Earth's history.
This discovery connects past biological adaptations to present scientific curiosity, showing how nature solves challenges over time.
