Answer Details

The key event in the transition of the amphibians from water to land is the replacement of the gills with lungs. This allowed them to extract oxygen from the air instead of extracting it from water through gills. As a result, amphibians could now survive in areas with little to no water, making it possible for them to venture onto land.
