Human evolution is a mystery that continues to intrigue. But even more mysterious is the diversification in animal species. Some lay eggs, and some give birth to live young. Some live on land while the others live in water. And there is no end to the magic some of them show by crossing over certain obvious lines. Amphibians are born in water and live on land. Marsupials have a unique external pouch on their body for their young. There are fish that walk on land and birds that don’t fly. What binds this world together is the magic of nature!
