The manner in which this Fish & Ornithorhyncus (Owen says most anomalous since ornithorhynchus) being intermediate between great groups, shows affinities to more than these two great groups, is vry interesting . & I think explicalbe on my theory. if we look at it as one descendant, which chance has preserved.— — —
Why, except frm fewness of species, is not Lepidosiren a family equal to Osseous or Plagiostomous fishes.
[passage scored]——
Hence some Fish & Perennibran breathe by two means —
——
   Means of passage frm one state to another as in Spiders
Now according to Waterhouse’s theory . (leaving unknown Leipidosiren) Pagiostomous fishes are nearest to Reptiles amphibians(?) & Perennibranchs— nearest of Amphibians, now I suspect these do approach each other in th aery points, viz lungs on th one hand (except lung-swimming bladder) & generative system on th others Now I daresay no two species in these groups approach nearer in the points in which these two groups; but yet probably two genera do, namely sharks & Siren & yet how unlike these groups.

Now if we take in Lepidosiren , then of all Fishes this family approaches nearest to Amphibians, & of th latter, the Perennibranchiata approach nearest to Fishes — but in those points in which Lep. does approach Amphibians, it does approch nearest to Perennibranc: & in those points in which Perennibranchiata approch nearest to fishes, thy do approch nearest to Lepidosiren.— Even perhaps Siren of Perennibran does approch nearest to Lepidosiren annectens or if Lepidosiren had contained many genera, it might have approached nearer to one than other. Probably no two species wd have approached— I think Waterhouse views must be restricted to two distant groups.— for by my theory if every fossil were found, there wd be a blending between all forms, but not direct between two groups, which implies immens extinction

For Waterhouses views two groups must be taken, & hist1 view must refer to species only — (though this is difficulty) for in his insistence of Bizacha, his argument applies to both species of Bizcacha.— So that in the higher groups his law applies to genera, & therefore his statement wd be that the alliance was not generic, but where genera are allied, relation not specific — I suspect requires much hesitationt2; can only be true by my theory owing to extinction— & Lepidosiren is exception. The most that ought to be said is that his law holds in many cases, & in two well defined groups, ie descended from distinct parent stocks.— t3

After having read some notes of Waterhouse1 on Mammals‒ I see that there are very few «intermediate» links between families. indeed such a half-way link wd form a new family. The link can generally be classed on either one, or other or third side. By my theory families far apart, have descended from some remote stock & there never will be any forms intermediate between the two, but between each, perhaps very different & the common centre.— this is important.— «Hence we shd never find an exact half way between Rodents & Marsupials. but between them latter & some unknown form & Rodent & same unknown forms.»t1 «but if Marsupiata were likt2 parent form, then you might»t3 I argue against circles, as inevitably giving idea of groups of equal value, which is an assumption without standard of comparison.— The circles touching represent equal affinities — this is at bottom of probability of Quinarian system.—  I suspect alliance of the links to other families is by saltus of a certain organ, thus Owen2 has discovered that vagina of Bizcacha is divided in Rodents, one

Waterhouse thinks most of the affinities between the grett2 families are "adaptive". This term vague & requires definition. Thus wombat is supposed to lead off by its teeth to Rodents, but teeth of Wombat really an Marsupial structure, but form of teeth merely adaptive.— The characters drawn from such parts as are common to several forms with different habits are best sign of real affinities & not being adaptive — thus vertebrate structures & such peculiarities in teeth as run through whole of Marsupiata— though here we get into vagueness, for

Phil. Trans. 1843. p. 240. Dr. A. Farre on th organ of Hearing in Crustacea. — Speculates , that as th organ is placed in th basal article of th antennae, & as th ciliated processes within th vestibular sack repeat th form of th antennae, he speculates most ingeniously whether the organ of hearing is not, "but a repetition, upon a most refined scale, of th form of an organ of touch ".— I may allude to this , when saying I have nothing to do with origin of senses — again I may allude to th sensibility to light in Hydra & such things, & mem. M. Edwards doctrine, that physiological action does not depends on organs.—

Swainson's statement (& Waterhouse independently to me) that typical genera (which implies with respect to larger group) (for Ornithorhynchust2 can only be considered non-typical with respect to Mammifers) have wide ranges (⸮ converse may still hold good?) is important; for the genera which are not typical are only rendered so by the extinction of allied genera, & that implies they are less adapted than other groups of genera to the theirt3 world & their co-inhabitants — & therefore one might expect they wd be less widely distributed: they «(as genera)» wd be rare, for they have or are descreasing in number — like individual species.—

v. Hooker's letter on what Typical means. I do not doubt it only refers to extinction. or rather fewness of forms .= Hookers statement makes fewness of osculant groups a truism.—
Linn. Trans. vol 18 p. 417.1 it is very curious that "so aberrant a form" (Silphomorpha &c. & 4 carabidous peculiar genera) "should be found in regions so distant in N. America, Brazil & N. S. Wales. This fact alone I shd imagine must be considered sufficient to prove that a wide geographical range is not the character of a typical group. as stated by Mr Swainson".

Athenaeum    1845 p. 199. Lecture by Prof. Forbes before R. Institution (perhaps will be published) — theoretical [passage scored]paper. — speaks of affinities branching off low down in each series — thus highest plant is not related to lowest animal, but a low plant to a low animal —
Thus low Molluscous animals is related to fish.—
Speaks much of analogies being parallel in series ; of aberrant forms representing structure of neighbouring series — of "analogy chiefly regarding form"— quite true (?) whale & fish.—
Much abstruse, perhaps mystical.—

Against my theory, it may be urged & has often occurred to me, that there ought to be intermediate forms — but I forget not half-way between bird & Reptile, but some third form equally connected with both. — But there is another consideration, that from the mouse in which we see groups in same «order or» class are connected, we shd expect not «a form» an intermediate in every character, but like in one part to «the» one side & in another organ to another. And this at once give rise to extreme difficulty in knowing what would be intermediate.

It is an old argument, but seeing the possibility wonderful metamorphoses, whether in egg or womb, or as free animals, which all undergo, it is strange, that the possibility, I do not say probability, of a germ in course of ages undergoing equally grett1 changes, has not modified our dislike of the view.—

  • 1. This note may record the point where CD turned his concerted attention to the issue that had been hanging fire since the end of Notebook E in 1839, namely: formulating what became the Principle of Divergence in Natural Selection 227-50 and Origin 111-29. It is one of a substantial out pouring of notes written on a grey wove paper in October and particularly in November 1854, many of which CD dated individually. This specific note is unusual on two counts. It is one of only a few in this series that was written in pencil and it was written in what, for Darwin, was an unusually jumpy handwriting. Compare the hand in this note (DAR 205.5: 148) with CD's steady hand in DAR 205.5: 149. Also compare the jumpy pencil writing in DAR 205.5: 148 with a typical pencil annotation in DAR 205.5: 147. What then made CD's hand jump as he wrote this note? In his Autobiography 68-9, he wrote:

    But at that time I overlooked one problem of great importance; and it is astonishing to me, except on the principle of Columbus and his egg, how I could have overlooked it and its solution. This problem is the tendency in organic beings descended from the same stock to diverge in character as they become modified. That they have diverged greatly is obvious from the manner in which species of all kinds can be classed under genera, genera under families, families under sub-orders and so forth; and I can remember the very spot in the road, whilst in my carriage, when to my joy the solution occurred to me; and this was long after I had come to Down. The solution, as I believe, is that the modified offspring of all dominant and increasing forms tend to become adapted to many and highly diversified places in the economy of nature.

    We suggest that DAR 205.5: 148 is a plausible candidate for a note written in pencil as Darwin's carriage bumped along one of the lanes around Down House. But if this is correct there are two important qualifications, which make this more than a curiosity. First, this note would then not only be a record of the event remembered in the Autobiography, but it would also be the first in the series of notes dated November 1854. Second, the content of the note is in fact not the full blown Principle of Divergence, instead it is a statement of the problem of divergence. To paraphrase the note, 'only descent explains why classification produces a branching pattern'. This sets the problem; but how does that branching occur? Perhaps the solution had already occurred to Darwin during the course of the carriage ride. But he actually first enunciated the core idea in note DAR 205.9: 250 [1854.11.01], written on the same grey wove paper: 'There is no law of Progression, but times wd. give better chance of sports, & allow more selection; & all the organisms thus living an advantage, — a «free» competition of labour,— the result wd be more complicated & more perfect' (emphasis added). If this is the correct sequence, then DAR 205.5: 148 must also have been written on 1 November 1854, thus dating the problem and the solution to the same day. Sixteen years and one month after the Malthus episode, drawing once again on political economy, Darwin thought he saw how selection could produce the diversity of life.

It is indispensable to show that in small & uniform areas there are many Families & genera.

  • 1. CD's thinking in this passage is at the interesection of his long standing interests in geographic distribution and classification. But one can also understand this passage as shaping the impetus for CD's field and lawn experiments at Down, which began a few months later in Summer 1855. In these experiments, he focussed on establishing diversity, quite literally as he says here, in 'small & uniform areas'. In this November 1854 note, the small 'area' of interest is a small geographic range. By July 1855 CD would focus on a field adjacent to the Sandwalk (see DAR 205.5: 157) and simultaneously on a three-foot square plot in the Sandwalk wood (see DAR 205.2: 119). Then in 1856 he would begin observations on a patch of unmown lawn (Lawn Experiment Note, Down House EH 88202556), and in 1857 he would set up his 'Weed Garden' in the Down orchard (Experiment Book 24-5). Thus in 1855-1857 he would initiate increasingly systematic experiments in which he used small plots as minimal experimental units of geographic range.

Aug./55/1 Those who believe in distinct creations, would argue with respect to division in groups, that if A is made adapted to certain conditions, under slightly different, but analogous conditions, as on mountain summit, another species B wd have to be created, & so on. And if species were all representative species this wd. hold good, at least primâ facie : but habits &c of species of same genus are often so very different, that this will hardly suffice. still less in worst cases will it hold with genera; why shd. otter, dog, cat belong to same Family? because all carnivorous. Why Bat, seal & Hare belong to same. Why shd. the water Ranunculus be a Ranunculus at all, it meets with no conditions analogous to the land Ranunculus. Why Cuscuta a Convolvulus.—

But the August 1855 note, loose sheet tipped into the Questions & Experiments Notebook (), is the voucher specimen for a slightly lighter grey paper, which he carried on using until at least October 1855.

  • 1. Larch wood was a part of Great Pucklands, the field belonging to Sir John Lubbock, that is adjacent and to the West of the Sandwalk at Down. A section of the field was a larch plantation. In July 1855, CD and Miss Thorley, the Darwin childrens' nurse counted the plant species in Great Pucklands and clearly included the Larch wood section of the 'field'. See letter to J. D. Hooker, 5 June [1855] 'Miss Thorley & I are doing a little Botanical work (!) for our amusement, & it does amuse me very much, viz making a collection of all the plants, which grow in a field, which has been allowed to run waste for 15 years, but which before was cultivated from time immemorial;' (Also Natural Selection 230-31.) In CD's statement that 'All classification follows from more distinct forms being supported on same area.' we see not only the intent behind the Thorley plant count, but also a juncture between CD's theoretical musings and experimentation at Down. .

We see sub-genera of dogs.— cabbages, potatoes.— Hence without seeking cause we might expect it in nature.— Cause no doubt is that when a form is domesticated it is distributed & exposed to many conditions & selected to vari various sub-ends.— When a particularly variety happens to be formed it spreads largely & is again subjected to variation. Should some analogous animal take place of dog, then is so much common in nature of all races of dogs that all probably would be exterminated.— Thus, we may instance Isid. G. St Hilaires prophecy that the tame Auchenias (are there many races?) of S. America will be lost through introduction of Cattle & Sheep & Horses in S. America.— So if Australia had breeds of Marsupials this would have happened.— Probably in plants some

On distinct Creation, how anomalous, that these smallest newest, & most wretched islds should possess species to themselves.— Probably no case in world like Galapagos. no hurricanes.— islds never joined. Nature & climate very different from adjoining coasts. admirable explanation is thus offered.— From these views, one would infer that Mullusca would offer few species, or rather be very slowly changed & vertebrata much so.— so far true, but do not fish offer a most striking anomaly to this.

  • 1. Very important for understanding development of the divergence diagram interpretation/ scenario: i.e. the theme of selection for extremes!!!! (which Richards challenged me on.) Date of December 1856 is very important as it means he went to work extending the principle, whose fine structure had crystallized in September of 1856, to exactly said scenario of selection for extremes. The Sept 1856 point we can see from passage quoted from Kohn 2008: 'Sept 23d /1856/ The advantage in each group becoming as different as possible, may be compared to the fact that by division of land labour most people can be supported in each country— Not only do the individuals of each group strive one against the other, but each group itself with all its members, some more numerous, some less, are struggling against all other groups, as indeed follows from each individual struggling— (Kohn 2006, DAR 205.5: 171) These passages have a lot in common. Divergence and struggle are linked in both and we can take the division of labor as a given in August 1855. The main difference is that in September 1856 we see nested intraspecific and interspecific struggles, the signature structure of divergence in the Origin. So if there was one point where the adaptive argument of the principle of divergence clicked, then this was it, just as Ospovat said nearly 30 years ago (1981).'

In a letter of 26 Nov [1856?], CD gingerly poses a question that went to the heart of his views on the function of flowers in cross fertilisation (). 'I venture a beg a favour of you. I have rather a wild bit of speculation afloat on the crossing of plants; & the Leguminosæ are my determined enemies, & worst of all are any forest-trees of this order.' While there is no surviving record of a letter from Bentham in response, a letter from CD a few days later refers to an earlier conversation with Bentham: 'you once told me before, about the apetalous Leguminosæ, & I think I wrote down other names besides Ononis, Lespediza & Clitoria' ().
