12. The Beginning of Life: Questions
By the end of the lesson you will be able to answer these questions:
What is the scientific theory of how life came about called?
Where did life begin on Earth?
Why have some species survived and others have not? (Everyone should be able to answer this. Some of you will be able to give the scientific word for what happens to creatures which do not survive).

13. The Beginning of Life: Evolution
Life started in the water with single celled creatures
Over millions of years these early life forms grew into different creatures. Some lived in the sea.
Some grew legs and lived on both land and sea
Gradually, some developed fur instead of scales...even 30 million years ago there were many mammals
Others grew wings to find more food
The ape-like creatures began to walk on their hind legs, leaving their hands free to do things like make tools. This was the beginning of human kind.
Finally, over 1 million years ago, ape-like creatures developed.

14. The Beginning of Life: Explanation
The word “evolution” simply means “change”.
The scientific Theory of Evolution says that animals and plants have evolved into the species we see today because they have developed ways of fitting their environment.
Creatures which no longer suited their environment (like dinosaurs) became extinct (died out).
