I think that the most important process of the evolution of life is when animals had to develop and go to land.his needed several adaptations, such as the growth of legs and arms, the size changing and the changes in the skin of this animals. They needed physical adaptations as theu´re corporal temperature. Also animals began to walk, that helped them to develop and to make more species. As eggs where laid on land new enivronments were found, making land a main place of life. The new environments needed the adaptations from the creatures if they wanted to survive.
