What is the role of water in the evolution of aquatic life?
Answers
Answer:
Marine life, or sea life or ocean life, is the plants, animals and other organisms that live in the salt water of the sea or ocean, or the brackish water of coastal estuaries. At a fundamental level, marine life affects the nature of the planet. Marine organisms produce oxygen and sequester carbon. Shorelines are in part shaped and protected by marine life, and some marine organisms even help create new land. The term marine comes from the Latin mare, meaning sea or ocean.
Most life forms evolved initially in marine habitats. By volume, oceans provide about 90 percent of the living space on the planet.[1] The earliest vertebratesappeared in the form of fish,[2] which live exclusively in water. Some of these evolved into amphibianswhich spend portions of their lives in water and portions on land. Other fish evolved into land mammals and subsequently returned to the ocean as seals, dolphins or whales. Plant forms such as kelpand algae grow in the water and are the basis for some underwater ecosystems. Plankton forms the general foundation of the ocean food chain, particularly the phytoplankton which are key primary producers.

Answer:
water plays important role in the evolution of Aquatic life. aquatic animals need water for their survival without this they cannot live for survival on the the Earth surface. where there is no water present on the earth not only aquatic animal cannot survive and also human cannot survive. our Earth has one -fourth part of the Earth surface is land and third fourth of its part is water but it is not the pure form of water only one percent of water in the form of glacier and we drink from the tube Wells.
