Hola friend!!
Rajdeep here...
Mutation is a sudden change in the number or structure of genes or chromosomes, due to which there are appearances of certain characters, which may not have existed in the generation of parents, grandparents or great-grandparents.
As said earlier, Mutation leads to PERMANENT change in characters. Change in characters may even lead to certain disorders.
For example, the atom bomb blast in Hiroshima and Nagasaki during the Second World War has led to mutation in the genes of people...The ones who survived gave birth to defective offsprings...the diseases are still persisting!

Hello,
Mutation is the ultimate source of variation. Without variation there could be no evolution, so mutations are of great importance to evolution. Important to point out that existing variation can be reshuffled by a variety of mechanisms that we don't always consider as mutations leading to increases or decreases in variation and thus altering the potential for evolution.
