Charles Darwin · 1837-1859 (major composition period; published 1859)
CHAPTER I. VARIATION UNDER DOMESTICATION. > CHAPTER I. (1/22)

Darwin argues that cultivated plants and animals show greater individual variability than wild ones because domestication involves less uniform living conditions and can require several generations to produce noticeable change.

CHAPTER I. VARIATION UNDER DOMESTICATION. > CHAPTER I. (18/22)

He claims horticulture shows selection’s cumulative effects, citing gooseberry growth and comparisons of flowers, leaves, and fruit among varieties to argue for small changes building into distinct races.

if he wants any of these qualities, he will assuredly fail. Few would readily believe in the natural capacity and years of practice requisite to become even a skilful pigeon-fancier. The same principles are followed by horticulturists; but the variations are here often more abrupt. No one supposes that our choicest productions have been produced by a single variation from the aboriginal stock. We have proofs that th…

Darwin argues that complex relations among organisms create shifting outcomes, illustrating with Staffordshire heath planted with Scotch fir, where birds, plants, and insect communities change after enclosure.

some cause, possibly in part through facility of diffusion amongst the crowded animals, been disproportionably favoured: and here comes in a sort of struggle between the parasite and its prey. On the other hand, in many cases, a large stock of individuals of the same species, relatively to the numbers of its enemies, is absolutely necessary for its preservation. Thus we can easily raise plenty of corn and rape-seed,…

He adds that cattle can determine Scotch fir survival in Staffordshire, but in places like Paraguay a fly limits feral herbivores, with insectivorous birds regulating the whole cascading system of interdependence.

effects of frequent intercrossing, and the ill effects of close interbreeding, probably come into play in some of these cases; but on this intricate subject I will not here enlarge. Many cases are on record showing how complex and unexpected are the checks and relations between organic beings, which have to struggle together in the same country. I will give only a single instance, which, though a simple one, has int…

Darwin closes the section by claiming English plant reproduction depends on specialized insects—moths, humble-bees, and field mice—and that cats could indirectly shape flower frequency through these chains.

firs. Yet the heath was so extremely barren and so extensive that no one would ever have imagined that cattle would have so closely and effectually searched it for food. Here we see that cattle absolutely determine the existence of the Scotch fir; but in several parts of the world insects determine the existence of cattle. Perhaps Paraguay offers the most curious instance of this; for here neither cattle nor horses …

Darwin argues that numerous ecological checks acting at different times determine species survival, using examples of plant competition, insect predation, and how closely related individuals often outcompete each other.

of a feline animal in large numbers in a district might determine, through the intervention first of mice and then of bees, the frequency of certain flowers in that district! In the case of every species, many different checks, acting at different periods of life, and during different seasons or years, probably come into play; some one check or some few being generally the most potent, but all concurring in determin…

He continues that competition is often strongest among species in the same genus, then states a key idea: organisms’ structures are related to competitors, prey, and escape, as shown by teeth, claws, and seed dispersal.

up for half a dozen generations, if they were allowed to struggle together, like beings in a state of nature, and if the seed or young were not annually sorted. As species of the same genus have usually, though by no means invariably, some similarity in habits and constitution, and always in structure, the struggle will generally be more severe between species of the same genus, when they come into competition with …

Charles Darwin · 1837-1859 (major composition period; published 1859)
CHAPTER I. VARIATION UNDER DOMESTICATION. > CHAPTER IV. (8/30)

Darwin argues that plants with more pollen and larger anthers can be naturally selected, leading to regular insect-mediated pollen transfer and eventually greater separation of male and female sex functions in plants.

were destroyed, it might still be a great gain to the plant; and those individuals which produced more and more pollen, and had larger and larger anthers, would be selected. When our plant, by this process of the continued preservation or natural selection of more and more attractive flowers, had been rendered highly attractive to insects, they would, unintentionally on their part, regularly carry pollen from flower…

CHAPTER I. VARIATION UNDER DOMESTICATION. > CHAPTER IV. (9/30)

Using an imaginary coevolution, Darwin explains how increased nectar rewards and small changes in insect feeding anatomy can favor tighter plant–bee mutual adaptation and lead to reciprocal modifications.

the division of labour, individuals with this tendency more and more increased, would be continually favoured or selected, until at last a complete separation of the sexes would be effected. Let us now turn to the nectar-feeding insects in our imaginary case: we may suppose the plant of which we have been slowly increasing the nectar by continued selection, to be a common plant; and that certain insects depended in …

Charles Darwin · 1837-1859 (major composition period; published 1859)
CHAPTER I. VARIATION UNDER DOMESTICATION. > CHAPTER IV. (12/30)

He supports occasional cross-fertilisation by citing flower structures that expose or enclose reproductive organs, bee-driven pollen transfer in pea-like flowers, and cases where close pollen can be prepotent yet foreign pollen is blocked.

from another species, the former will have such a prepotent effect, that it will invariably and completely destroy, as has been shown by Gärtner, any influence from the foreign pollen. When the stamens of a flower suddenly spring towards the pistil, or slowly move one after the other towards it, the contrivance seems adapted solely to ensure self-fertilisation; and no doubt it is useful for this end: but, the agency…

Darwin argues that many trees have separated male and female flowers, allowing pollen to move between flowers and trees, and that terrestrial animals rarely if ever self-fertilise, unlike aquatic animals aided by currents.

are crossed the case is directly the reverse, for a plant’s own pollen is always prepotent over foreign pollen; but to this subject we shall return in a future chapter. In the case of a gigantic tree covered with innumerable flowers, it may be objected that pollen could seldom be carried from tree to tree, and at most only from flower to flower on the same tree, and that flowers on the same tree can be considered as…

CHAPTER I. VARIATION UNDER DOMESTICATION. > CHAPTER V. (7/24)

Darwin concludes on acclimatisation: habit may be hereditary, species ranges are limited by competition and not just climate, and some imported plants show different cold-resisting constitution over time.

surprised that more wrecks of ancient life have not been preserved, owing to the less severe competition to which the inhabitants of these dark abodes will probably have been exposed. *Acclimatisation*.—Habit is hereditary with plants, as in the period of flowering, in the amount of rain requisite for seeds to germinate, in the time of sleep, etc., and this leads me to say a few words on acclimatisation. As it is ex…

Darwin weighs the roles of habit, use and disuse, and natural selection in acclimatization, citing agricultural advice, climate-tuned plant varieties in the United States, and experiments (or lack of them) on Jerusalem artichoke and kidney-beans.

or sub-tropical in their habits, ought not to be looked at as anomalies, but merely as examples of a very common flexibility of constitution, brought, under peculiar circumstances, into play. How much of the acclimatisation of species to any peculiar climate is due to mere habit, and how much to the natural selection of varieties having different innate constitutions, and how much to both means combined, is a very o…

CHAPTER I. VARIATION UNDER DOMESTICATION. > CHAPTER VI. (21/21)

He explains unity of type as unity of descent and treats conditions of existence as the higher law, since natural selection and inherited adaptations shape structures through growth, use/disuse, and adaptation over past time.

look only to the present inhabitants of the world, is not strictly correct, but if we include all those of past times, it must by my theory be strictly true. It is generally acknowledged that all organic beings have been formed on two great laws—Unity of Type, and the Conditions of Existence. By unity of type is meant that fundamental agreement in structure, which we see in organic beings of the same class, and whic…

Darwin lays out rules from Gärtner on hybridisation: fertility grades from zero to full, varies with conditions and individuals, and is governed partly by systematic affinity though not strictly.

known to be a sign of incipient fertilisation. From this extreme degree of sterility we have self-fertilised hybrids producing a greater and greater number of seeds up to perfect fertility. Hybrids from two species which are very difficult to cross, and which rarely produce any offspring, are generally very sterile; but the parallelism between the difficulty of making a first cross, and the sterility of the hybrids …

He introduces reciprocal crosses (male/female roles can change outcomes), notes systematic-affinity limits, and describes how hybrid fertility and resemblance can be decoupled from each other, with examples like Mirabilis and Matthiola.

Annual and perennial plants, deciduous and evergreen trees, plants inhabiting different stations and fitted for extremely different climates, can often be crossed with ease.

He uses grafting as an analogy to show compatibility can be limited by reproductive/structural differences rather than purpose, noting examples where grafting can render plants barren or increase fruit, paralleling hybrid fertility.

then to stop their further propagation by different degrees of sterility, not strictly related to the facility of the first union between their parents, seems to be a strange arrangement. The foregoing rules and facts, on the other hand, appear to me clearly to indicate that the sterility both of first crosses and of hybrids is simply incidental or dependent on unknown differences, chiefly in the reproductive system…

CHAPTER I. VARIATION UNDER DOMESTICATION. > CHAPTER VIII. (15/18)

Darwin reports several experiments: maize crosses yielding few seeds yet fertile hybrids, gourd crosses varying with differences, Verbascum color varieties producing less seed in same-color versus crossed trials, and tobacco varieties showing altered fertility with Nicotiana glutinosa.

it is important to notice that the hybrid plants thus raised were themselves *perfectly* fertile; so that even Gärtner did not venture to consider the two varieties as specifically distinct. Girou de Buzareingues crossed three varieties of gourd, which like the maize has separated sexes, and he asserts that their mutual fertilisation is by so much the less easy as their differences are greater. How far these experim…

In the central parts of the Chonos Archipelago (lat. 45 degs.), the forest has very much the same character with that along the whole west coast, for 600 miles southward to Cape Horn. The arborescent grass of Chiloe is not found here; while the beech of …

The larger islands alone possess springs, and these are always situated towards the central parts, and at a considerable height. The tortoises, the…

They feed by day, and do not wander far from their burrows; if frightened, they rush to them with a most awkward gait. Except when running down hill, they cannot move very fast, apparently from the lateral position of their legs. They are not at all timorous: when att…

Darwin argues that reef-building corals only survive down to about 20–30 fathoms, so Pacific and Indian coral atolls must have formed on shallow foundations that later subsided.

well as in the crater-theory, a most important consideration has been overlooked, namely, on what have the reef-building corals, which cannot live at a great depth, based their massive structures? Numerous soundings were carefully taken by Captain Fitz Roy on the steep outside of Keeling atoll, and it was found that within ten fathoms, the prepared tallow at the bottom of the lead, invariably came up marked with the…

Darwin recounts documentary history of St. Helena’s Great Wood converting to wire grass between 1716 and 1724, credits goats and hogs for killing saplings, and infers downstream effects on insects and land-shell extinctions.

extinction has probably been caused by the entire destruction of the woods, and the consequent loss of food and shelter, which occurred during the early part of the last century. The history of the changes, which the elevated plains of Longwood and Deadwood have undergone, as given in General Beatson's account of the island, is extremely curious. Both plains, it is said in former times were covered with wood, and we…

Locke distinguishes identity in plants from identity in mere masses of matter, arguing an oak remains the same plant through a continuous organized life despite continual replacement of material particles.

5. Identity of Vegetables. We must therefore consider wherein an oak differs from a mass of matter, and that seems to me to be in this, that the one is only the cohesion of particles of matter any how united, the other such a disposition of them as constitutes the parts of an oak; and such an organization of those parts as is fit to receive and distribute nourishment, so as to continue and frame the wood, bark, and …

It were therefore to be wished, That men versed in physical inquiries, and acquainted with the several sorts of natural bodies, would set down those simple ideas wherein they observe the individuals of each sort constantly to agree.
