ZOONOMIA

Two kinds of generation¹

influence living beings. —

We see living beings the young of living beings, become permanently changed or subject to variety, according to circumstances, — seeds of plants sown in rich soil, many kinds, are produced, though new individuals produced by buds are constant, hence we see generation here seems a means to vary, or adaptation. Again we believe (know) in course of generations even mind and instinct become influenced. —

On this idea of propagation of species we can see why a form peculiar to continents, all bred in from one parent

This is answer to Decandolle¹ (his argument applies only to hybridity), — genera being usually peculiar to same country,
different genera, different countries.

¹ Augustin-Pyramus de Candolle. Essai élémentaire de géographie botanique, Strasbourg 1820, p. 60: "Les différences constantes des végétaux nés dans diverses régions ne semblent sa rapporter ni à l'une ni à l'autre de ces classes [ = produites par les élémens extérieurs + formées par l'hybridité] on ne peut les attribuer aux circonstances externes, … on ne peut les attribuer à l'hybridité … [Les] espèces sont distribuées sur le globe en partie d'aprés des lois qu'on peut immédiatement déduire de la combinaison des lois connues de la physiologie et de la physique, en partie d'après les lois qui paroissent tenir à l'origine des choses et qui nous sont inconnues." (This question was discussed by Lyell, Principles of Geology, vol. 2, London 1832, p. 56.) [deB]

Propagation explains why modern animals same type as extinct which is law almost proved. —

We can see why structure is common is common in certain countries when we can hardly believe necessary, but if it was necessary to one forefather, the result would be as it is. — Hence Antelopes at C. of Good Hope, —

With this tendency to change (& to multiplication when isolated requires deaths of species to keep numbers

but is there any reason for supposing numbers of forms equable? — this being due to subdivisions and amount of differences, so forms would be about equally numerous

As many terminal buds dying as new ones generated

There is nothing stranger in death of species than individuals

If we suppose monad definite existence, as we may suppose in this case, their creation being dependent on definite laws, then those which have changed most owing to the accident of positions must in each state of existence have shortest

23

life. Hence shortness of life of Mammalia.

Would there not be a triple branching in the tree of life owing to three elements

air, land & water, & the endeavour of each one typical class to extend his domain into the other domains, and subdivision three more, double arrangement. —

24

if each main stem of the tree is adapted for these three elements, there will be certainly points of affinity in each branch
A species as soon as once formed by separation or change in part of country repugnance to intermarriage increases it settles it

؟ We need not think that fish & penguins really pass into each other. —

The tree of life should perhaps be called the coral of life, base of branches dead; so that passages cannot be seen. — this again offers

26

contradiction to constant succession of germs in progress

no only makes it excessively complicated.

Is it thus fish can be traced right down to simple organization. — birds — not?

We may fancy according to shortness of life of species that in perfection, the bottom of branches deaden,
so that in Mammalia, birds, it would only appear like circles, & insects amongst articulata. — but in lower classes perhaps a more linear arrangement. —

35

؟ Is the shortness of life of species in certain orders connected with gaps in the series of connections?

If starting from same epoch certainly

The absolute end of certain forms from considering S. America (independent of external causes) does appear very probable: —

Mem: Horse, Llama, &c., &c. —

If we suppose grant similarity of animals in one country owing to springing from one branch, and the monucle has definite life, then all die at one period which is not the case, ∴ monucule not definite life.

36

I think

[sketch]

Case must be that one generation then should be as many living as now. To do this & to have many species in same genus (as is) requires extinction.

Thus between A & B immense gap of relation. C & B the finest gradation, B & D rather greater distinction. Thus genera would be formed. — bearing relation

37

to ancient types. — with several extinct forms

for if each species an ancient (1) is capable of making 13 recent forms¹, twelve of the contemporarys must have left no offspring at all², so as to keep number of species constant. —

With respect to extinction we can easy see that variety of ostrich, Petise may not be well adapted, and thus perish out, or on other hand like Orpheus being favourable

² In the diagram there are 12 lines that are without a perpendicular line at the end. [Ba]

38

many might be produced. — This requires principle that the permanent varieties produced by inter confined breeding & changing circumstances are continued & produced according to the adaptation of such circumstances, & therefore that death of species is a consequence (contrary to what would appear from America)

39

of non-adaptation of circumstances. —

Vide two, pages back.

Diagram

The largeness of present genera renders it probable that the many contemporary, would have left scarcely any types of their existence in the present world. — or we may suppose only each species in each generation only breeds; like individuals in a country not rapidly increasing. —

40

If we thus go very far back to look to the source of the Mammalian type of organization; it is extremely improbable that any of his relatives shall likewise the successors of his relations shall now exist — In same manner, if we take a man from any large family of 12 brothers & sisters in a state which does not increase

41

it will be chances against any one of them having progeny living ten thousand years hence; because at present day many are relatives, so that by tracing back the descen fathers would be reduced to small percentage. — & in therefore the chances are excessively great against any two of the 12. having progeny after that distant period.¹ —

¹ In this and in the preceding paragraphs Darwin to all intents and purposes formulates the postulates of his theory of natural selection, viz., the survival of the fittest and the constancy of populations generation after generation.[Ba]

42

Hence if this is true, that the greater the groups the greater the gaps (or solutions of continuous structure) between them. — for instance, there would be great gap between birds and mammalia, Still greater between

43

Vertebrate and Articulata, still greater between animals & Plants.

But yet, besides affinities from three elements, from the infinite variations, & all coming from one stock & obeying one law, they may approach, — some birds may approach animals, & some of the vertebrates invertebrates —

Such a few on each side will yet present some anomaly & the g bearing

44

stamp of some great main type, & the gradation will be sudden.

Heaven know whether this agrees with Nature: Cuidado.¹

The above speculations are applicable to non progressive development
which certainly is the case at least during subsequent ages. —

¹ Darwin no doubt has reference to the Quinary System of classification described by Macleay, William Sharp, in Horae entomologicae; or, essays on the Annulose animals, etc., vol. 1, pts. 1, 2, London, 1819, 1821. William Swainson also described the system in A treatise on the geography and classification of animals, London, Longman, etc., in Lardner, D., The Cabinet Cyclopaedia. 1835. The system was based on the postulate that the animal kingdom may be classified into five major divisions and that these divisions have such a relation to each other that they form a circle when grouped together according to morphological similarities. Thus each division includes some taxonomic forms which bear a close resemblance through affinities or analogics to two of the other major divisions. Since each of the five major divisions is related by some of its members to two of the remaining divisions, the entire group of five must have a circular arrangement amongst themselves. Also each of the five major divisions itself was thought to be composed of five smaller taxonomic units, each of which similarly was circularly related to two of the five units within its division.

Fries in 1825, under the title of Systema Orbis Vegetabilis." - p. 86: "When the members of a bipartite section are again dichotomously divided upon analogous principles, four sections are created, of which the first and second, and the third and fourth, are in affinity; but the first and third, and the second and fourth, are in analogy. But when this method of division becomes circuitous, a more direct path is undoubtedly to be discovered: hence other numbers are admitted, especially the quaternary (or double dichotomy), and also others in which dichotomy is understood."

Why does individual die, to perpetuate certain peculiarities (therefore adaptation), & to obliterate accidental varieties, & to accomodate itself to change (for of course change even in varieties is accomodation).

The relation of Analogy of Macleay¹ &c., appears to me the same, as the irregularities in the degradation of structure of Lamarck², which he says depends on external influences. — For instance he says wings of bat are from external influence. —

¹ William Sharp MacLeay. Horae Entomologicae, London 1819–1821. The "relations of analogy" are conceived as "existing between corresponding points of the two contiguous circles which pass through a perfect change of form" (p. 391) e.g. the Decapoda in the Crustacean circle have "relations of analogy" with the Araneidea of the Arachnid circle, while the latter's Acaridea have "relations of analogy" with the Diptera of the Haustellata circle. [deB]
² Jean-Baptiste de Lamarck. Philosophie Zoologique. Paris 1809 1: 153: degradation is the result of less progress in the perfection and composition of the organization, and must be distinguished from the effects of environment and contracted habits. E.g., seals owe their imperfect limbs to the water in which they live, as do whales; but seals are less degraded than whales because their organization is less degraded in its essential parts. [deB]

If population of place be constant (say 2000) and at present day every ten living souls on average are related to the (200th year) degree. then 200 years ago there were 200 people living who now have successors. — Then the chance of 200 people might be being related within 200 years backward might be calculated & this number eliminated. say 150 people four hundred years since were progenitors of present people, and so on backwards to one progenitor, who might have continued breeding from eternity backwards.

147

If population was increasing between each lustrum, the number related at the first start must be greater, & this number would vary at each lustrum, & the calculation of chance of the relationship of the progenitors would have different formula for each lustrum. —

Un hasard favorable a peut-être porté, par un enchainement particulier de circonstances, des semences pardessus les montagnes. Abandonnée à elle-même, la variété qui résulte des nouvelles conditions auxquelles elle est soumise, y formera, avec le cours du temps, une espèce distincte, qui s'èloigne d'autant plus de sa forme primitive, qu'elle reste plus longtems dans cette région isolée, exempte d'autres influences."

When species cross & hybrids breed, their offspring show tendency to return to one parent, this is only character, & yet we find this same tendency (only less strongly marked) between what are called varieties.

A plant submits to more individual change, (as some animals do more than others, & cut off limbs & new ones are formed)

but yet propagates varieties according to same law with animals??

Why are species not formed, during ascent of mountain or approach of desert? — because the crossing of species less altered prevents the complete adaptation which would ensue

211

A. B. C. D. (A) crossing with (B), and (B) being crossed with (C) prevents offspring of A becoming a good species well adapted to locality, but it is instead a stunted & diseased form of plant, adapted to A. B. C. D. Destroy plants B. C. D. & A will soon form good species!

The increased fertility of slightly different species & intermediate character of offsprings accounts for uniformity of species & we must confess that we cannot tell, what is the amount

212

of difference which improves & checks it. It does not bear any precise relation to structure.

Mem.: Eyton's Hogs & dogs.¹

The passage in last page explains that between species from moderately distant countries there is no test but generation (but experience according to each group) whether good species, & hence the importance naturalists attach to Geographical range of species. —

Definition of species: one that remains at large with constant characters, together with other animals beings of very near structure. — Hence species may be good ones & differ scarcely in any external character; — For instance two wrens forced to haunt two islands, one with one kind of herbage & one with other, might change organization of stomach & hence remain distinct.

214

Where country changes rapidly we should expect most species —

The difference intellect of man & animals not so great as between living things without thought (plants) & living things with thoughts (animals).

∴ my theory very distinct from Lamarck's,¹

Without two species will generate common kind which is not probable,² then monkeys will never produce man, but

¹ Darwin's point appears to be that Lamarck placed a great distinction between the higher animals which possessed a "sentiment intérieur", and the lower animals which do not. (Philosophie Zoologique, Paris 1809 2: 256). [deB]
² I believe Darwin means that under his theory two distinct species would not independently evolve into a single species. [Ba]

215

both monkeys & man may produce other species. man already has produced marked varieties & may someday produce something else, but not probable owing to mixture of races. — When all mixed & physical changes (؟intellectual being acquired alters case) other species or angels produced,

216

Has the Creator since the Cambrian formation gone on creating animals with same general structure — miserable limited view. —

With respect to how species are Lamarck's "willing" doctrine absurd (as equally are arguments against it — namely how did otter live before being modern otter — why to be sure there were a thousand intermediate

217

forms. — Opponent will say. show them me. I will answer yes, if you will show me every step between bull Dog & Greyhound)¹ I should say the changes were effects of external causes, of which we are as ignorant as why millet seed turns a Bullfinch black, or iodine on glands of throat, or colour of plumage altered during passage of birds (where is this statement, I remember L. Jenyns² talking of it?), or how to make Indian cow with hump and pig's foot with cloven hoof.

Is the Flora of S. America Tierra del Fuego like that of North Europe, many genera & few species.

The number of genera on islands & on Arctic shores evidently due to the chance of some ones of the different orders being able to survive or chance having transported them to new station. — When the new island splits & grows larger species are former of those genera & hence by same chance few representative species. This must happen, and then enquiry will explain representative Systems. Of this we see example in English & Irish Hare, — Galapagos shrews & when big continent many species belonging to its own genera

It agrees with excessive inequality of numbers of species in divisions. look at articulata!!! —

226

It leads to nature of physical change between one group of animals & a successive one. — It leads to knowledge what kinds of structure may pass into each other; now on this view no one need look for intermediate structure between say in brain between lowest Mammal & Reptile (or between extremities of any great divisions) thus a knowledge of possible changes is discovered, for speculating on future.

∴ fish never become a man. — does not require fresh creation: — If continent had sprung up round Galapagos on Pacific side, the Oolite¹ order of things might have easily been formed. —

Any change suddenly acquired is with difficulty permanently transmitted. — It will admit a plant will admit of a certain quantity of change at once, but afterwards will not alter.

It is scarcely possible to get evidence of two races of plants run wild — (for we know that such can take place without impregnating each other), for if they are different then they will be called species, & mere producing fertile hybrids will not destroy that evidence, as so many plants produce hybrids, or else whole fabric will be overturned. — Hence extreme difficulty, argument in circle. — Falkland Is^d case good one of animals not soon being subjected to change in Americas perhaps merely gone back previous

Are the closest allied species always from distant countries, as Decandelle¹ says? No, he only says sometimes
we might expect disseminated species to vary a little, but such should not be general circumstance. — In insects in England surely it is not; intermediate genera we might expect. —
