An attempt to study the evolution of living organisms without reference to cytology would be as futile as an account of stellar evolution which ignored spectroscopy.

The evolutionists, piercing beneath the show of momentary stability, discovered, hidden in rudimentary organs, the discarded rubbish of the past. They detected the reptile under the lifted feathers of the bird, the lost terrestrial limbs...

Every hour of your life that ticks by, there are numerous points and moments when you can choose to pause – and be aware of your mental and physical state. At any given point, you...

The source of man is in man,and when a man dies,millions of men die in him.

One way of emphasizing the singularity of the recent past is [..] to observe that the total number of humans ever to have lived is estimated at around (a bit less than) 100 billion. One...

Of the contributions made during the essayist period three call for notice: Weismann deserves mention for his useful work in asking for the proof that “acquired characters” or, to speak more precisely, parental experience can...

Stephen Hawking said that his quest is simply “trying to understand the mind of God”.

Darwin, with his Origin of Species, his theories about Natural Selection, the Survival of the Fittest, and the influence of environment, shed a flood of light upon the great problems of plant and animal life.These...

Oh I believe in loving cats and dogs and children and parents – sometimes – but I don’t believe in romantic love. Of course, there’s the momentary rush of hormones and chemicals that encourages us...

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...

When one ponders on the tremendous journey of evolution over the past three billion years or so, the prodigious wealth of structures it has engendered, and the extraordinarily effective teleonomic performances of living beings from...

I know that certain minds would regard as audacious the idea of relating the laws which preside over the play of our organs to those laws which govern inanimate bodies; but, although novel, this truth...

If a single cell, under appropriate conditions, becomes a man in the space of a few years, there can surely be no difficulty in understanding how, under appropriate conditions, a cell may, in the course...

Insects are major players in nature’s recycling effort, and in nature a corpse is simply organic matter to be recycled. Left to its own devices, nature quickly populates a corpse with a diverse community of...

According to the concept of transformational evolution, first clearly articulated by Lamarck, evolution consists of the gradual transformation of organisms from one condition of existence to another.

Molecular biology has shown that even the simplest of all living systems on the earth today, bacterial cells, are exceedingly complex objects. Although the tiniest bacterial cells are incredibly small, weighing less than 10-12 gms,...

The typical imperative from biology is not “Thou shalt… ,” but “If … then … else.

What, after all, is so special about genes? The answer is that they are replicators. The laws of physics are supposed to be true all over the accessible universe. Are there any principles of biology...

From year to year, and from age to age, we see [biologists] at work, adding no doubt much to the unknown, and advancing many important interests, but, at the same time, doing little for the...

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...

There is no sharp boundary line separating the reactions of the immune bodies from chemical processes between crystalloids, just as in nature there exists every stage between crystalloid and colloid. The nearer the colloid particle...

To suppose that the eye with all its inimitable contrivances for adjusting the focus to different distances, for admitting different amounts of light, and for the correction of spherical and chromatic aberration, could have been...

Dire .. que l’homme est constitué de certains éléments chimiques est une description ne convenant qu’à ceux dont l’intention est de l’utiliser comme engrais.

The starting point of Darwin’s theory of evolution is precisely the existence of those differences between individual members of a race or species which morphologists for the most part rightly neglect. The first condition necessary,...

…Why is it, that from the moment you enter medical school to the moment you retire, that the only disorder you will ever diagnosis with a physics book – is obesity? This is biology folks,...

To list all the great discoveries in the field of science and medicine during the past century, such as aspirin, insulin, penicillin, and the streptomycin drugs would require the undivided attention of a medical historian...

An irrefutable proof that such single-celled primaeval animals really existed as the direct ancestors of Man, is furnished according to the fundamental law of biogeny by the fact that the human egg is nothing more...

All social animals, including people, live under constant pressure from two competing interests: protecting themselves from others and aligning themselves with others. When these two interests are balanced, the result is dynamic social homeostasis.

winning or losing an agonist encounter has a dramatic impact on future aggressive behavior. Winners are more likely to initiate attacks against unknown opponents, whereas losers are more circumspect and likely to retreat from unfamiliar...

The very comprehensibility of the world points to an intelligence behind the world. Indeed, science would be impossible if our intelligence were not adapted to the intelligibility of the world. The match between our intelligence...

I simply would not accede to being forced into this, and would frequently be kept out of classes because of irreverent comments and mocking this religious stuff. Frankly, it stayed with me to this day....

It is difficult to overstate the importance of understanding mirror neurons and their function. They may well be central to social learning, imitation, and the cultural transmission of skills and attitudes—perhaps even of the pressed-together...

Perhaps if zoologists would contemplate the wide variations presented by many plants of indubitably one and the same species, and the still wider diversities of long cultivated races from an original stock, they would find...

It has been demonstrated that a species of penicillium produces in culture a very powerful antibacterial substance which affects different bacteria in different degrees. Generally speaking it may be said that the least sensitive bacteria...

The race is now on between the technoscientific and scientific forces that are destroying the living environment and those that can be harnessed to save it. . . . If the race is won, humanity...

My ex girlfriend and I, we had chemistry together. And right after that, we had biology.

Evolution on the large scale unfolds, like much of human history, as a succession of dynasties.

A sound Physics of the Earth should include all the primary considerations of the earth’s atmosphere, of the characteristics and continual changes of the earth’s external crust, and finally of the origin and development of...

Who gave the decisive deathblow to the argument from design on the basis of biological complexity? Both philosophers and biologists are divided on this point (Oppy 1996; Dawkins 1986; Sober 2008). Some have claimed that...

The woman who later became his wife was sleeping in his bed, her face buried in the pillows and her feet crossed on top of each other like a child’s. He watched her sleep and...

The outgroup is rocks.

I submit a body of facts which cannot be invalidated. My opinions may be doubted, denied, or approved, according as they conflict or agree with the opinions of each individual who may read them; but...

The history of the knowledge of the phenomena of life and of the organized world can be divided into two main periods. For a long time anatomy, and particularly the anatomy of the human body,...

The ideology and philosophy of neo-Darwinism which is sold by its adepts as a scientific theoretical foundation of biology seriously hampers the development of science and hides from students the field’s real problems.

All the more recent work on alkaptonuria has… strengthened the belief that the homogentisic acid excreted is derived from tyrosine, but why alkaptonuric individuals pass the benzene ring of their tyrosine unbroken and how and...

I think it’s reasonable to suppose that one could oscillate between being biologically 20 and biologically 25 indefinitely.

It necessarily follows that chance alone is at the source of every innovation, and of all creation in the biosphere. Pure chance, absolutely free but blind, at the very root of the stupendous edifice of...

In a very real sense we have two minds, one that thinks and one that feels

Evolution is an integration of matter and concomitant dissipation of motion during which the matter passes from an indefinite incoherent homogeneity to a definite coherent heterogeneity, and during which the retained motion undergoes a parallel...

Information and complexity go hand in hand.
