Hey ! Today we talk about giraffe and its evolution. I wonder why it has a so long neck ?
The giraffe used to have a short neck but sometimes a giraffe with a longer neck appeared
This long neck was very practical during famine when food was rare. Giraffe with a long neck could catch leaves higher up in trees. So during famine, long neck giraffe were outliving, short neck giraffe, who died sooner. So short neck giraffe disappear because they wasn't adapted to the environnement. This phenomenon is call the natural selection
It's for that today giraffe has a long neck. It's the end of the story I hope you learn new things about the evolution of the giraffe. Bye !!!
