In the beginning, about four billion years ago, the air was unfit to breathe. The young earth is without life. The sun beats down; storms lash the coasts; volcanoes pour hissing lava into the ocean’s waters. These natural jolts fuse simple molecules into more complex ones. Amino acids are formed, then interact with each other, and primitive protein is fashioned, perhaps as a worm-like molecule. Somehow the right molecules get together and the first living cell appears. This first living cell is the great ancestor of all plants and ******* on earth, including man. From this first cell, all other forms of life evolved. This tiny first living cell is the ****** of us all!
How did man come from this first cell? (Remember, there are more cells in the human body than there are people in the world) Here's the story: As time went on, this first cell developed into amoeba-like organisms and other primitive creatures that could survive in the ocean. After millions of years, these creatures evolved into fish. Some of these fish developed lungs so that they could survive outside of the water. Gradually they began to make their way onto land as the first amphibians. These amphibians then evolved into reptiles and the earth soon became populated with great dinosaurs. Some of these reptiles started to develop legs that could move around better, and these creatures became what we today would call mammals. Other reptiles developed wings and flew away to become birds.
Where did man come from? One of these early mammals was known as a tree shrew. He was not much larger than a squirrel and in many ways looked like a squirrel. This creature lived in trees and gradually evolved into primitive monkeys and other ape-like creatures. From these ape-like creatures there evolved two major groups: 1) the great apes that we can see in zoos today, such as the gorilla, orangutan, gibbon and chimpanzee; 2) a creature who came down from the trees and who started walking upright (all monkeys and apes walk on all fours)--THIS IS MAN!
Our ****** (that first living cell) would have been very proud of us if he could have seen how far we have come these past millions of years!
