Quote by Hugo de Vries

"Mutation is the only source of novelty in evolution"

"Nature does not proceed by leaps"

"The origin of species lies in the nature of variation"

"Evolution is a process of continuous change"

"The pen is mightier than the sword."

"Literature opens the mind to new worlds"

"The interesting thing about books is that they're made of words."

"Literature captures the essence of what it means to be human."
