Life is believed to have first emerged in the ocean, with simple single-celled organisms appearing around 3.5 billion years ago. The transition to land began with plants, specifically mosses and liverworts, around 470 million years ago, followed by arthropods like insects and crustaceans. Vertebrates, such as amphibians, were among the first animals to make the leap to land approximately 360 million years ago. This progression marked the gradual colonization of terrestrial environments by various life forms.
