31 6 Full Breakdown

Summary

Story summary

A recent study identified genetic changes that enabled animals to transition from water to land more than 500 million years ago.
Researchers analyzed the genomes of 150 species, finding that adaptations varied across lineages and that gene turnover drove land adaptation.
The study links land-based life to changes in Earth's atmosphere and mineral cycles, identifying three major waves of transitions shaped by ecological shifts.
