Quote by Stephen Jay Gould

"Evolution is a process of constant branching and expansion."

"We are here because one odd group of fishes had a peculiar fin anatomy that could transform into limbs for terrestrial creatures."

"The most important evolutionary change may have been the development of consciousness itself."

"Science simply represents an honest attempt to find truth about the natural world."

"Perseverance is the key to success."

"Don't give up on what you believe in."

"I've been through worse."

"You learn to live with the pain."
