Adaptation Quote by Anonymous
“The facts of variability, of the struggle for existence, of adaptation to conditions, were notorious enough; but none of us had suspected that the road to the heart of the species problem lay through them, until Darwin and Wallace dispelled the darkness.”

CHARLES DARWIN, On the Origin of Species (1859)” quote by Robert Harris](https://sms4smile.com/quotes/img-quotes/4a0/robert-harris-2039_life_the-struggle-for-existence-almost-invari_2506732.jpg)
