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"

"I love my wife, but sometimes she drives me crazy."

"Love conquers all obstacles."

"Love is patient, love is kind."

"I'm not stupid, I'm just in love!"
