The waters are teeming Grade 5

Grandpa Flex tells an interesting story about the first vertebrates, fish, how they moved out of the water and their progress to life and land. Scientist had naturally guessed what the earliest clumsy, ancient fishes must have looked like to be able to crawl out of the water and explore life on land. Fossils were even found to support the scientists’ assumptions – fossils of giant lobe-finned fish, which had fins that looked like primitive legs!
