“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.”
― Richard Dawkins, The Selfish Gene

“Different sorts of survival machine appear very varied on the outside and in their internal organs. An octopus is nothing like a mouse, and both are quite different from an oak tree. Yet in their fundamental chemistry they are rather uniform, and, in particular, the replicators that they bear, the genes, are basically the same kind of molecule in all of us—from bacteria to elephants. We are all survival machines for the same kind of replicator—molecules called DNA— but there are many different ways of making a living in the world, and the replicators have built a vast range of machines to exploit them. A monkey is a machine that preserves genes up trees, a fish is a machine that preserves genes in the water; there is even a small worm that preserves genes in German beer mats. DNA works in mysterious ways.”
― Richard Dawkins, The Selfish Gene

“Prediction in a complex world is a chancy business. Every decision that a survival machine takes is a gamble, and it is the business of genes to program brains in advance so that on average they take decisions that pay off. The currency used in the casino of evolution is survival, strictly gene survival, but for many purposes individual survival is a reasonable approximation.”
― Richard Dawkins, The Selfish Gene

“The genes supply the motivation for warfare, [E. O.] Wilson is saying, in humans as they do in chimps, but people, blessed with the power of language, look for some objective cause of war. A society psychs itself up to go to war by agreeing that their neighbors have wronged them, whether by seizing property or failing to deliver on some promise. Religious leaders confirm that the local deity favors their cause and off go the troops. ”

“{On to contributions to evolutionary biology of 18th century French scientist, Georges-Louis Leclerc, Comte de Buffon}

He was not an evolutionary biologist, yet he was the father of evolutionism. He was the first person to discuss a large number of evolutionary problems, problems that before Buffon had not been raised by anybody.... he brought them to the attention of the scientific world.

Except for Aristotle and Darwin, no other student of organisms [whole animals and plants] has had as far-reaching an influence.

He brought the idea of evolution into the realm of science. He developed a concept of the "unity of type", a precursor of comparative anatomy. More than anyone else, he was responsible for the acceptance of a long-time scale for the history of the earth. He was one of the first to imply that you get inheritance from your parents, in a description based on similarities between elephants and mammoths. And yet, he hindered evolution by his frequent endorsement of the immutability of species. He provided a criterion of species, fertility among members of a species, that was thought impregnable.”
― Ernst Mayr

“There's no end to evolution.”

“Too much tension is a disease; but so is too little. There are certain occasions when we ought to be tense, when an excess of tranquility (and especially of tranquility imposed from the outside, by a chemical) is entirely inappropriate.”
― Aldous Huxley, Moksha: Writings on Psychedelics and the Visionary Experience

“Evolution is all about turning "bugs" into "features", turning "noise" into "signal", and the fuzzy boundaries between these categories are not optional; the opportunistic open-endedness of natural selection depends on them.”

“Our species has co-evolved alongside many others to which we were in contact, especially through scavenging, hunting, and then animal husbandry, all of which would have exposed us to novel pathogens and zoonotic diseases. As a species, we had to adapt to these new pathogens without the benefits of modern medicine. The newly emerging diseases of recent decades, while novel in themselves, are but a repeat of patterns which humans have survived over several millennia.”
― Kimberly A. Plomp, Palaeopathology and Evolutionary Medicine: An Integrated Approach

“Today there are almost eight billion people on earth, crowded together and travelling widely -this is 1300 times more than were present when the agricultural revolution began around 10,000 years ago and facilitated the spread of many pathogens.”
― Kimberly A. Plomp, Palaeopathology and Evolutionary Medicine: An Integrated Approach

“Humans have always lived surrounded by potential pathogens. Whether they co-exist relatively harmlessly or become a problem, cause acute or chronic disease and spread slowly or in epidemics has been, and still is, influenced by how we have impacted the environments we share with other animals. Pathogens are opportunists within these environments, capable and ready to take advantage of anything that promotes their transmission.”

“Consider the least stable way to arrange an animal's body: it would be to stand it upright. To seee the biomechanics of a human skeleton walk and run -to stand on one foot and not fall, as most humans can easily do- is to witness a marvel of motion and balance, as robot engineers are learning their cost.
Bipedalism was the enabler of subsequent brain growth.”

“While many things that seem useless turn out to have a function, others are abysmal designs. The eye would be better without a blind spot. The birth canal is too narrow. Cancer protection mechanisms are insufficient, as are those that protect against infection. Ability to regulate eating is weak. Anxiety and pain are often excessive.”

“The greatest boon of modern life is also the greatest villain: the availability of plentiful food. Or, rather, foodlike substances manufacturers concoct with the exact combinations of sugar, salt, and fat that we most desire. Those desires were helpful on the African savanna, where sugar, salt, and fat were scarce; now our preferences make us obese and ill. Addiction to tobacco was not much of a problem until the breeding of milder strains and the invention of cigarette papers; now smoking causes a third of all cancers and much heart disease. Fermented beverages were sometimes available, but now readily available beer, wine, and spirits cause alcoholism worldwide. Advances in chemistry and transport make concentrated drugs such as heroin and amphetamine available everywhere; in combination with novel means of administration such as needles, they cause massive modern epidemics.”
― Randolph M. Nesse, Good Reasons for Bad Feelings: Insights from the Frontier of Evolutionary Psychiatry

“Many of our current health problems result, nonetheless, from the environments we have created to satisfy our desires. Most people in developed societies live better now physically than the kings and queens of just a century ago. We have a surfeit of delicious food, protection from the elements, time for leisure, and relief from pain. The accomplishments are spectacular, but they also cause most chronic disease.”

“In many species, males pay for sex. For example, among black ticked hanging flies, an amorous male will present a female with a nice, juicy insect and then copulate with her while she distractedly enjoys her meal. If the female finishes before he does, she simply walks away. Game over. If, on the other hand, he finishes first, he snatches the insect away and tries to woo another female with the leftovers.”

“The general rule is that whatever females want, males evolve to provide it.”

“Karl Marx suggested that people should produce according to their abilities but share according to their needs, and this maxim describes hunter-gatherers reasonably well. But the history of communism suggests that agricultural people don’t share very well outside their family. The problem with the Marxist utopia is that people can free-ride on the efforts of others. If you are required to share with me, then I’m tempted to put in a little less effort because I know your hard work will leave me well fed. Once you see me slacking off, you don’t want to be a sucker, so you slack off a bit yourself, and pretty soon everyone is barely working. The free-rider problem is a vicious circle and can quickly destroy a productive community if there is no way to police everyone’s contribution.”

“True. And there are an infinite number of universes, of course, in which we don't exist at all - that is, no creatures similar to us exist at all. In which the human race doesn't exist at all. There are an infinite number of universes, for instance, in which flowers are the predominant form of life -or in which no form of life has ever developed or will develop.”

“At the same time, animals that are very cognitively complex tend to have a slow development (although there are exceptions to this, such as the common octopus, whose life expectancy in the wild barely surpasses one year, and yet they are exceedingly smart).”
