Life's Journey from Sea to Land

The video explores the origins of animal life in the ocean and the transition of certain phyla to land. It highlights the arthropods' success in dominating terrestrial environments due to their exoskeletons and jointed appendages. Despite arthropods' current dominance, the video suggests that molluscs, with their vast oceanic diversity, may have a significant future on land as sea levels rise.
