Animal life is believed to actually have begun on land, with some animals later moving into the water. Simple animals are known to have developed as early as 2 billion years ago, with gradually more complex organisms appearing, until a very short and huge expansion of life. This is thought to have happened around 550 to 530 million years ago, in what is called the Cambrian explosion.
Plant life is understood to have originated in the water, and then either moved onto land or some combination of movement with preexisting land growth. Evidence for plantlife on land is varied, some being as old as 1.2 billion years although the majority of the oldest remains are 450 million years old.
