1)​

Answer 1

Scientists now estimate that 80 percent of Earth's species live on land, 15 percent in the ocean, and the remaining 5 percent in freshwater.

Half a billion years ago on Earth, after the Cambrian explosion had created an astonishing array of new species, there was still no life on land. No complex life anyway. No plants, no animals, certainly nothing that even compared to the great diversity of life in the sea, which teem

with trilobites, crustaceans, bristly worms, and soft squid-like creatures. Most major animals groups that exist today originated in the sea at this time.
