The kidneys are a pair of bean-shaped organs on each side of your spine<span>, under your ribs and behind your belly. Each kidney is about
4 or 5 inches long, roughly the size of a large fist. It goes to the
kidneys to extract water from the excretory system and put it back into the blood.

Evolution is the change in heritable traits of biological populations over successive generations.
What is evolution of life?
- Evolution has produced the variety of life that exists on Earth today. Since life first emerged on Earth between 3.5 and 4 billion years ago, it has continued to develop.
- At initially, there were just single-celled, primitive species on Earth.
- The first multicellular organisms appeared much later, and as a result, the diversity of life on Earth significantly increased.
- Darwin put out a substantial amount of evidence to back up his idea of evolution by natural selection.
- Evolution is the gradual alteration of a living thing's traits over time. Natural selection is the process of evolution.
- Through their DNA, organisms transmit their traits from one generation to the next.
