Darwin was not the first to consider evolution as a processes but he did come up with the first effective explanation for how it happens. Describe Darwin\'s theory of evolution by natural selection. Explain how this theory was a major advance over prior ideas as to how organisms changed over time. Give evidence in support of evolution and describe the driving forces for evolutionary change. Darwin was not the first to consider evolution as a processes but he did come up with the first effective explanation for how it happens. Describe Darwin\'s theory of evolution by natural selection. Explain how this theory was a major advance over prior ideas as to how organisms changed over time. Give evidence in support of evolution and describe the driving forces for evolutionary change. Solution Darwin theory was based on the study of size of small birds beaks which were found on the Galapoes island.. He found that with time and areas the size of the bird\'s beak were different in size and shape ie their size increases. . This were due to the fact that the due to to the avalaibilty of their different foods their beaks size also changes and increased in size..!! It was due to the evolution which was further carried out to their future generations..!! The driving force are those forces which results in evolution.. The factors are Mutation Natural selection. Gene flow. Genetic drift..

Solution
Darwin theory was based on the study of size of small birds beaks which were found on the
Galapoes island.. He found that with time and areas the size of the bird's beak were different in
size and shape ie their size increases. . This were due to the fact that the due to to the avalaibilty
of their different foods their beaks size also changes and increased in size..!! It was due to the
evolution which was further carried out to their future generations..!!
The driving force are those forces which results in evolution..
The factors are
Mutation
Natural selection.
Gene flow.
Genetic drift.
