Species Quotes

“There are many examples where species share common plastic traits. What appears to be convergence may just be the plastic response of the organism to its environment. Examples include the following: Limbs that protrude from an animal’s body have more surface area per unit mass than the rest of the body. In cold weather the animal loses more heat per unit mass from these limbs than from other parts of the body. In many species the tails and legs are shorter for those living in colder climates and larger for those in warmer climates. Gulls’ wings are shorter in cold climates than in warm. Hares and foxes also have shorter ears in cold climates than in warm. Eskimos have shorter arms and legs than do people living in warmer climates. . . . Jodan’s rule: Many species of fish tend to have more vertebrae when they live in cold water than do the same species living in warm water. These differences have been shown to depend on the temperature at which the fish have been reared.”

“Each species may have had its origin in a single pair, or individual, where an individual was sufficient, and species may have been created in succession at such times and in such places as to enable them to multiply and endure for an appointed period, and occupy an appointed space on the globe.”

“They say that animals are incapable of feelings and reasoning. This is false. No living thing on earth is void of either. They also say that man is the most intelligent — and the most superior — species on earth. This is also false. It is very arrogant to assume that we are the most intelligent species when we keep repeating the same mistakes over and over again. It has been shown that both rats and monkeys learn from making errors, yet we have not. Our history proves this. All creatures on earth have the capacity to love and grieve the same way we do. No life on the planet is more deserving than another. Those who think so, are the true savages.”

“There can be no doubt that the existing Fauna and Flora is but the last term of a long series of equally numerous contemporary species, which have succeeded one another, by the slow and gradual substitution of species for species, in the vast interval of time which has elapsed between the deposition of the earliest fossiliferous strata and the present day.”

“Yes, the human race is a small species in an infinite universe filled with many other planets and many other things, but though small; this race is bearer of very great and big things: Destiny, Virtue, Hope, Love... and that's what makes this species different. That's what makes this species very shiny and very visible and very important, in a whole, whole, big, big, vast, expanding universe!”

“We, of all the beings that we know of, can think. We can eat, write, build, save. We can predict, estimate, and count. We can preserve food for lifetimes, and in times of crisis, we can find ways to ensure our survival. With each passing generation, our sphere of control of our existence is larger. What if the earth is hit by an asteroid or there is no way to stop global warming? We look to colonize other planets. The fate of our species, in a few years, will not be tied to the fate of the earth. Our home planet must be cared for ... but as we go interplanetary and then interstellar, our control on our lives and the evolution of our species grows. As far as we know, we are the only species that has a say in the development of its future.”

“Far from being the smartest possible biological species, we are probably better thought of as the stupidest possible biological species capable of starting a technological civilization - a niche we filled because we got there first, not because we are in any sense optimally adapted to it.”

“The more a species is rare the more we like and protect it... So what about humans?”

“The time scale for evolutionary or genetic change is very long. A characteristic period for the emergence of one advanced species from another is perhaps a hundred thousand years; and very often the difference in behavior between closely related species -say, lions and tigers- do not seem very great... But today we do not have ten million years to wait for the next advance. We live in a time when our world is changing at an unprecedented rate. While the changes are largely of our own making, they cannot be ignored. We must adjust and adapt and control, or we perish.”
