The dry areas of land now known as deserts once had water and were bursting with life.
The predecessor of the camel lived without the familiar hump on their back because it was not necessary.
As time passed, the deserts began to dry up and water became more scarce.
Eventually one of the predecessors was born with a hump on its back. It was a helpful mutation, as it allowed for the animal to store some water in the hump.
The camels with the mutation survived longer than the others who died from dehydration. This means that they were more likely to mate and pass down the hump.
Through years of further evolution, we are now left with the modern-day camel, able to sustain a significant amount of water in its hump and survive the dry environment called a desert.
