Can someone one explain me in one short para about the theory of evolution?
The theory of evolution says that life forms change to adapt to their surroundings. As climates, predators, or other factors change, and perhaps as a result of random genetic mutation, life changes as well. How this happens is not, strictly speaking, a part of the theory of evolution. Darwin proposed something called “natural selection”, which said that life forms best adapted to their environment were the ones who survived to breed and pass on their adaptations. You may have heard this referred to as “survival of the fittest”. Most people agree that natural selection is insufficient to explain evolution, so there must be something else going on. Most people disagree as to exactly what this is, although mutation probably plays a large part. Evolution, though, just says that life forms change, as I said above.
