Rise of Animals

The video is trying to explain about where vertebrates like us and other creatures that already have bones today came from. Scientists found fossils inorder to prove their beliefs of our origin and tend to examine these fossils inorder to make theories or conclusions about how the vertebrates started. Back in my younger years, when I was a child, it's not that I'm against science but I just could not believe in their theories like dinosaurs exists or these things exist through these fossils and that bones. But a lot of videos including the one we watched, already proves a lot that it may be possible or it really is possible for things to exist. Atleast we may have something to know about the origin of the world's creatures and how it evolves through years.

Those early vertebrates started in the sea, long long time ago. Soon enough evolved with legs and lungs that introduced the land species called Amphibians. These creatures have their eggs laid underwater inorder for it to survive the environment. Then soon amphibians developed and evolved into another species called Reptiles, They have hard skins and are cold-blooded. The first reptiles on this earth were called Dinosaurs that were already extinct long long ago. Then soon evolved into mammals which are warm-blooded and could survive the environment more than the previous species. They can lay their eggs on land. Then mammals evolved into birds that could rule the skies. They use their wings to fly, much more amazing than mammals.
