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"

"Never let fear stop you from chasing your dreams."

"Courage is being afraid but doing it anyway."

"Sometimes you gotta do what you gotta do."

"Sometimes you have to be the monster to stop the monsters."
