Story summary
- Researchers explored the genetic basis of animal adaptations to life on land, analyzing genomes of 150 species over the past 500 million years.
- Researchers identified universal adaptations and lineage-specific innovations, noting three major waves of transitions from water to land driven by ecological changes.
- The findings show adaptations such as stress response and barrier defenses reshaping Earth's atmosphere and ecosystems, with some genetic changes common and others rare.
