+ f. X5 x- K: @lyell(1797-1875) was most famous for his book:"principles of Geology- An attempt to explain the former changes of the earth's surgace by reference to causes now in operation". this book argues about how the earth's surface was shaped the it is due to countless little changes all add together to form the earth that we see today. this goes against what many people had believed, because during that time, people had believed that supernatural events are the reasons for them such as the Noah's flood.

Lyell tried to find the link between all observeble causes, earthquakes, tides and the state of the earth today. he talked about changes caused both by organic and inorganic, and how they had contribute to the earth's shape. he promoted the idea of uniformitarianism which became a great contribution to geology today.

he influenced darwin by inspire him with the idea of grually changes, uniformitarianism, and darwin accepted this idea and expande it into biology where he had came to the idea that all species evolves gradually and dies out gradually. and forces that we still see today such as reproduction, competition and inheritance are what effected the changes and diversity of all species living on earth.
