Hello, all of you who are reading this, you are my family. Why, you might think am I saying this? It is because we all developed from one form of life called "Simple life forms." Then complex life formed. Then trees and plants formed. Next the dinosaurs. Then the Ice age. Next the cave men. Then the modern human formed. Do you know how different species formed? Well, think of of it like this; a horse has a baby. but this horse baby (called a calf) was different. It had a long neck and long legs and had spots. Then that baby grew up and had babies that looked like it. I think that's how the giraffe was developed.
