Top 13 Vertebrates Quotes & Sayings

We can now determine, easily and relatively cheaply, the detailed chemical architecture of genes ; and we can trace the products of these genes ( enzymes and proteins ) as they influence the course of embryology . In so doing we have made the astounding discovery that all complex animal phyla - arthropods and vertebrates in particular - have retained, despite their half-billion years of evolutionary independence, an extensive set of common genetic blueprints for building bodies.

Ever since then, all descendant vertebrates have had the forward end of the digestive system and the forward end of the respiratory system very much involved with each other. This manifests itself in the human body with a crossing of the two systems in the throat.

With nine degrees of warming, computer models project that Australia will look like a disaster movie. Habitats for most vertebrates will vanish. Water supply to the Murray-Darling Basin will fall by half, severely curtailing food production.

Structurally we should understand that one cannot think that the human brain is different from the brain of the other vertebrates. It is an important question, because we can investigate what is the difference between the brain of a mouse and ours, and of course the difference is enormous, in size and capacity.

If you confine yourself to this Skinnerian technique, you study nothing but the learning apparatus and you leave out everything that is different in octopi, crustaceans, insects and vertebrates. In other words, you leave out everything that makes a pigeon a pigeon, a rat a rat, a man a man, and, above all, a healthy man healthy and a sick man sick.

Even something as complex as the eye has appeared several times; for example, in the squid, the vertebrates, and the arthropods. It's bad enough accounting for the origin of such things once, but the thought of producing them several times according to the modern synthetic theory makes my head swim

In time they sank and decayed, and nothing is left of them except an occasional impression in stones, in stones now found in deserts and on high mountain peaks. Birdless forests block the sun in uninhabited lands. Insects swirl in the air. And then, in a majestic, bloodthirsty, and mighty heave, the spinal columns of the vertebrates rise as monstrous lizards and fabulous creatures; dragons flinging their fearful bellows up to a steaming sky... Slowly they become birds, birds as light as undreamt dreams. The searing roars become birdsong, whimpering flutes on warm nights.

Brave men are all vertebrates; they have their softness on the surface and their toughness in the middle.

Advocates for a single line of progress encounter their greatest stumbling block when they try to find a smooth link between the apparently disparate designs of the invertebrates and vertebrates.

In the study of this membrane [the retina] I for the first time felt my faith in Darwinism (hypothesis of natural selection) weakened, being amazed and confounded by the supreme constructive ingenuity revealed not only in the retina and in the dioptric apparatus of the vertebrates but even in the meanest insect eye. ... I felt more profoundly than in any other subject of study the shuddering sensation of the unfathomable mystery of life.

Water is commonly regarded as the 'solvent of life,' since our bodies are 70% water. All other vertebrates, invertebrates, microbes, and plants are also primarily water. The organization of water within biological compartments is fundamental to life, and the aquaporins serve as the plumbing systems for cells.

Our children think our world will end. It's a tragic thing. Adults don't think that. They don't see that we are eating the planet. But we are. If you take all the biomass of vertebrates on the planet, 98% are men and their domestic animals. All the wild animals in the world make up only 2%.

Birds, it must be admitted, are the most exciting and most deserving of the vertebrates; they are perhaps the best entre into the study of natural history, and a very good wedge into conservation awareness.
