The act of making something different (as e.g. the size of a garment)

Usage examples of modification.

We shall thus see that a large amount of hereditary modification is at least possible, and, what is equally or more important, we shall see how great is the power of man in accumulating by his Selection successive slight variations.

Therefore I can see no difficulty, under changing conditions of life, in natural selection accumulating slight modifications of instinct to any extent, in any useful direction.

As its manifesto and program are practically identical with those of the Communist Party of America, while all its members are likewise affiliated with the Third or Moscow International, the foregoing characterization of the Communist Party applies without essential modification to the Communist Labor Party.

Although new and important modifications may not arise from reversion and analogous variation, such modifications will add to the beautiful and harmonious diversity of nature.

North America, and there discover a series of analogous phenomena, it will appear certain that all these modifications of species, their extinction, and the introduction of new ones, cannot be owing to mere changes in marine currents or other causes more or less local and temporary, but depend on general laws which govern the whole animal kingdom.

The effect of this was so astoundingly nasty that we shall not be referring to it again at any point in this narrative-other than to record briefly the fact that it caused Zaphod to throw up inside his suit, which he therefore removed and swapped, after suitable headgear modifications, with the empty one.

Some of them even go as far as to say that that the only thing needed for the further work on the bacteria hybrid was the bacteria itself, since it already had in itself all the tools required for any further modifications or upgrades, and that means that all the further development effort could be conducted at home.

It was Gibbs who had masterminded the sale of the Shark, a World War II, Gato- class submarine, to the Chilean government, and arranged its modifications to look like the Barracuda, before sinking it in fifteen hundred fathoms of water.

Whether such variability be taken advantage of by natural selection, and whether the variations be accumulated to a greater or lesser amount, thus causing a greater or lesser amount of modification in the varying species, depends on many complex contingencies,--on the variability being of a beneficial nature, on the power of intercrossing, on the rate of breeding, on the slowly changing physical conditions of the country, and more especially on the nature of the other inhabitants with which the varying species comes into competition.

The same modification that Carey had found to put a bend in the shield allowed Jane way to extrude the shield several hundred thousand kilometers in the direction of the bend.

With a few modifications, more horsepower, larger chassis and steering assembly, someplace to sit .

Additionally, both the Minuteman III and the Sego will require considerable modification for this mission.

It is, however, far more necessary to bear in mind that there are many unknown laws of correlation of growth, which, when one part of the organisation is modified through variation, and the modifications are accumulated by natural selection for the good of the being, will cause other modifications, often of the most unexpected nature.

But we may confidently believe that many modifications, wholly due to the laws of growth, and at first in no way advantageous to a species, have been subsequently taken advantage of by the still further modified descendants of this species.
