| Evolution - Life Begins |
 |
|
So how did life arrive on Earth?
What came first? The chicken, or the egg? This riddle seems silly, but think about it. Without chickens, there could be no one to lay eggs. Yet, without eggs, there could be no chickens, because they could not have hatched. So which came first? A complicated question, and not just about chickens, but about all life forms.

What forces changed this barren waist land into the beautiful garden that it is today? Biologists believe that the process that created life is something called evolution. Earth's ancient oceans, while lifeless, but were filled with the chemicals needed for life. These chemicals were not alive, but they were there, sloshing around. They call these chemicals “Primordial soup”. Instead of alphabets, this soup was filled with amino acids, proteins, lipids, and other basic components that are commonly found in life forms today. |

It is believed that life began on the shores of these ancient oceans, in pools of water called tidal pools. These shallow pools would have been full of this “life soup”. Over many millions of years, as the ingredients of life splashed around in these pools, possibly helped by lightning strikes, they formed the first cells.
