Uniformitarianism, states that the geological processes that take place today would have taken place in the past and it will continue in future as well.
Darwin suggested that the the evolution takes place over a period of time. It takes time to change and this change takes time.
Both the laws states the same thing, that the geological processes and the process of evolution takes place over a period of time and does not takes place rapidly.
Explanation: According to the law of Uniformitarianism, the geological processes that has been taking place now must have taken place in the past, and will also take place in future, at a constant speed, in long term.
Darwin suggested that the same Uniformitarianism process takes place in case of living beings also. According to him, these living creatures undergoes evolution and in this process, gradual changes in the organisms occurs being a long-term continuous process.
