Someone please rephrase this for me:(?

It means that if you look at nature, only the fittest survive. The stronger animals pray on the weaker ones. How can humans be created in the image of God when we are so like animals? Darwin looked at the way skeletons were made and quickly realised that many species were very similar. He suggest that we are not created by some fellow in the sky but by nature itself, that over millions of years, humans and animals have evolved.
