In every remote corner of the world there are people like Carl Jones and Don Merton who have devoted their lives to saving threatened species. Very often, their determination is all that stands between an endangered species and extinction. But why do they bother? Does it really matter if the Yangtze river dolphin, or the kakapo, or the northern white rhino, or any other species live on only in scientists' notebooks? Well, yes, it does. Every animal and plant is an integral part of its environment: even Komodo dragons have a major role to play in maintaining the ecological stability of their delicate island homes. If they disappear, so could many other species. And conservation is very much in tune with our survival. Animals and plants provide us with life-saving drugs and food, they pollinate crops and provide important ingredients or many industrial processes. Ironically, it is often not the big and beautiful creatures, but the ugly and less dramatic ones, that we need most. Even so, the loss of a few species may seem irrelevant compared to major environmental problems such as global warming or the destruction of the ozone layer. But while nature has considerable resilience, there is a limit to how far that resilience can be stretched. No one knows how close to the limit we are getting. The darker it gets, the faster we're driving. There is one last reason for caring, and I believe that no other is necessary. It is certainly the reason why so many people have devoted their lives to protecting the likes of rhinos, parakeets, kakapos, and dolphins. And it is simply this: the world would be a poorer, darker, lonelier place without them. ↗

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. ↗
Personally, I've always found the study of life incredibly boring – I much prefer to just live it. I do enjoy speculating on life, though. But to go and ruin that speculation by checking it against facts, it's terribly disappointing. I'm afraid it would turn me into a cynic. ↗

There are species that retain their characteristics even in conditions that are relatively different from their natural ones; other species in similar circumstances instead become extinct; otherwise what takes place is racial mixing with other elements in which no assimilation or real evolution occurs. The result of this interbreeding closely resembles Mendel’s laws concerning heredity: once it disappears in the phenotype, the primitive element survives in the form of a separated, latent heredity that is capable of cropping up in sporadic apparitions, even though it is always endowed with a character of heterogeneity in regard to the superior type. ↗
Некоторые критики ошибочно считают, что «Эгоистичный ген» проповедует эгоизм как нравственный принцип, которого мы должны придерживаться в жизни! Другие (возможно, потому, что они прочитали только заглавие книги или не пошли дальше первых двух страниц) полагают, что по моему мнению эгоизм и другие скверные черты характера составляют неотъемлемую часть человеческой природы, нравится нам это или нет. В эту ошибку легко впасть, если вы считаете, как, по-видимому, полагают непостижимым образом многие другие люди, что генетическая «детерминированность» дана нам навсегда, что она абсолютна и необратима. На самом же деле гены «детерминируют» поведение лишь в статистическом смысле (см. также с. 44–47). Хорошей аналогией этому служит широко распространенное мнение, что красный закат обещает ясную погоду на следующий день. Возможно, что по статистике красный закат действительно предвещает великолепную погоду назавтра, но никто не станет заключать об этом пари на крупную сумму. Мы прекрасно знаем, что на погоду действует множество факторов и притом очень сложными путями. Любое предсказание погоды подвержено ошибкам. Это всего лишь предсказание, опирающееся на статистику. Мы не считаем, что красные закаты бесспорно определяют хорошую погоду назавтра и точно так же мы не должны считать гены окончательными детерминантами чего бы то ни было. Нет никаких причин, чтобы влияние генов нельзя было повернуть в противоположную сторону с помощью других воздействий. ↗
Some people think mental illness is a matter of mood, a matter of personality. They think depression is simply a form of being sad, that OCD is a form of being uptight. They think the soul is sick, not the body. It is, they believe, something that you have some choice over. I know how wrong this is. When I was a child, I didn't understand. I would wake up in a new body and wouldn't comprehend why things felt muted, dimmer. Or the opposite--I'd be supercharged, unfocused, like a radio at top volume flipping quickly from station to station. Since I didn't have access to the body's emotions, I assumed the ones I was feeling were my own. Eventually, though, I realized these inclinations, these compulsions, were as much a part of the body as its eye color or its voice. Yes, the feelings themselves were intangible, amorphous, but the cause of the feelings was a matter of chemistry, biology. It is a hard cycle to conquer. The body is working against you. And because of this, you feel even more despair. Which only amplifies the imbalance. It takes uncommon strength to live with these things. But I have seen that strength over and over again. ↗
Janx Spirit : Janx Spirit is a rather potent alcoholic beverage, and is used heavily in drinking games that are played in the hyperspace ports that serve the madranite mining belts in the star system of Orion Beta. The game is not unlike the Earth game called Indian Wrestling, and is played like this: Two contestants sit at either side of a table, with a glass in front of each of them. Between them would be placed a bottle of Janx Spirit — as immortalized in that ancient Orion mining song : “Oh don’t give me no more of that Old Janx Spirit No, don’t you give me no more of that Old Janx Spirit For my head will fly, my tongue will lie, my eyes will fry and I may die Won’t you pour me one more of that sinful Old Janx Spirit” Each of the two contestants would then concentrate their will on the bottle and attempt to tip it and pour spirit into the glass of his opponent – who would then have to drink it. The bottle would then be refilled. The game would be played again. And again. Once you started to lose you would probably keep losing, because one of the effects of Janx spirit is to depress telepsychic power. As soon as a predetermined quantity had been consumed, the final loser would have to perform a forfeit, which was usually obscenely biological. ↗
Even when Darwin's teaching first made its appearance, it became clear at once that its scientific, materialist core, its teaching concerning the evolution of living nature, was antagonistic to the idealism that reigned in biology. ↗
Healing is a biological process, not an art. It is as much a function of the living organism as respiration, digestion, circulation, excretion, cell proliferation, or nerve activity. It is a ceaseless process, as constant as the turning of the earth on its axis. Man can neither duplicate nor imitate nor provide a substitute for the process. All schools of healing are frauds. ↗

That natural selection can produce changes within a type is disputed by no one, not even the staunchest creationist. But that it can transform one species into another — that, in fact, has never been observed. ↗
