organisms change over time

∙ 13y agoDarwin's mechanism for evolution was natural selection through gradual change in the genome in response to factors pressuring from the environment. Geological gradualism, the thought that large changes are an accumulation of smaller changes over time and uniformitarianism, the idea that geologic processes have remained constant over many many years, gave Darwin a geologic time frame in which his mechanism of natural selection could operate. The small genetic variations and mutations that accumulated in an organism to shape the drastic changes leading to the differentiation of new species needed constant environmental pressures over a long period of time. Gradualism and uniformitarianism allowed for both of these criteria and so influenced Darwin's theory of evolution by means of natural selection.

∙ 15y agoThe principle influence was Darwin reading Principles of Geology by Charles Lyell - he was given a copy by Robert Fitzroy (the captain of the Beagle) at the start of the Beagle's voyage around the world.
The main theme of Principles of Geology is uniformtarianism. This is the theory that the world was shaped by the gradual affect of observable processes. For example, a river valley is explained by the river gradually wearing through the rocks.
It is the idea of uniformtarianism that Darwin applied so successfully to explain how new species could evolve.

Wiki User
∙ 12y agobecause Darwin's was more accurated and lyells had absolutely nothing to do with it ahahhahahhaha
Wiki User
∙ 8y agoThe realization of deep geological time - the fact that the world was thousands of millions of years old - gave the time periods that would be required for Darwin's concepts to happen in.

What According to the theory of today's organisms evolved from past organisms?
No, that isn't a statement made about evolution. The theory of evolution concerns how organisms have changed over periods of time. Everything has to have come from something! However, all living organisms alive today have evolved from predecessors, or have not really evolved much at all, e.g. Gingko bilboa and several species of sea animals.
