1. Explain how the principle of gradualism and Charles Lyell's theory of
uniformitarianism influenced Darwin's ideas about evolution.
The basic idea of naturalselection is that a population of organisms can change over the generations if individuals having certain heritable traits leave more offspring...

One of his famous examples to in order to explain his point was “explanation of giraffe”. He suggested that every subsequence generation after the giraffe would slightly stretch its neck more.

Evolution as a theory
* Theory- in science, a well substantiated explanation of some aspect of the natural world
Evolution- the accumulation of inherited genetic changes within populations over generations
* Does not refer to changes that occur in an individual within its lifetime

Darwin’s theory of evolution is the major cornerstone of modern biology.
Evolution is one of the most important concepts in all of science. In biology, it has become a Unifying Principle, a concept of such central importance that nearly all...
