“I am an enthusiastic Darwinian, but I think Darwinism is too big a theory to be confined to the narrow context of the gene.”

“I am not an enthusiast for diversity of opinion where facts are concerned.”

“Individuals are not stable things, they are fleeting. Chromosomes too are shuffled into oblivion, like hands of cards soon after they are dealt. But the cards themselves survive the shuffling. The cards are the genes. The genes are not destroyed by crossing-over, they merely change partners and march on. Of course they march on. That is their business. They are the replicators and we are their survival machines. When we have served our purpose we are cast aside. But genes are denizens of geological time: genes are forever.”

“In the world of the extended phenotype, ask not how an animal's behaviour benefits its genes; ask instead whose genes it is benefiting.”

“Relatives share a substantial proportion of their genes. Each selfish gene therefore has its loyalties divided between different bodies.”

“Los genes operan de manera misteriosa.”

“Even if not a single fossil has ever been found, the evidence from surviving animals would still overwhelmingly force the conclusion that Darwin was right.”
