What were the animals that conquered the land?

The first inhabitants of the land were the simplest organisms and viruses. They already inhabited the area near water bodies, when complex life forms in water were just developing. The first animals that began to emerge from the water had adaptations both for living in water and for staying on land. They were amphibians. They developed limbs, lungs, ears and other body parts and organs. After a long time, those animals appeared that were independent of life in the reservoir. And all this happened due to the depletion of the aquatic habitat.
