7 分Our understanding of genetics has developed significantly since the mid-\( 19^{th} \) century through the work of many scientists.
a) Describe the theory of evolution by natural selection as proposed by Charles Darwin, explaining how variation within a species leads to the formation of a new species.
b) Darwin's theory was only gradually accepted after its publication in \( 1859 \). Give two reasons why many scientists and the public were initially reluctant to accept his ideas.
c) In the early \( 20^{th} \) century, it was observed that the 'units' of inheritance described by Gregor Mendel behaved in a similar way to chromosomes. Explain how the discovery of DNA structure in the mid-\( 20^{th} \) century finally allowed the gene theory to be fully developed.
