Volume I Part 32 (1/2)
At another place, speaking of interation of species by saying, why have not some interalonyx, Mastodon, and the species now living? Now according to ht be brother to Megatheriu elsewhere of intermediate forms, he remarks:--
”Opponents will say--'show them me' I will answer yes, if you will show reyhound”
Here we see that the case of do on the production of natural species The disappearance of intermediate forms naturally leads up to the subject of extinction, hich the next extract begins
”It is a wonderful fact, horse, elephant, andout about same time in such different quarters
”Will Mr Lyell say that some [same?] circumstance killed it over a tract from Spain to South Aolden pippins; it is a GENERATION OF SPECIES like generation OF INDIVIDUALS
”Why does individual die? To perpetuate certain peculiarities (therefore adaptation), and obliterate accidental varieties, and to accoe, even in varieties, is accouate he has no issue--so with species
”If SPECIES generate other SPECIES, their race is not utterly cut off:-- like golden pippins, if produced by seed, go on--otherwise all die
”The fossil horse generated, in South Africa, zebra--and continued--perished in Aether just like buds of plants, which die at one tih produced either sooner or later
Prove aniradation between associated and non-associated animals--and the story will be complete”
Here we have the view already alluded to of a ter note we get extinction connected with unfavourable variation, and thus a hint is given of natural selection:
”With respect to extinction, we can easily see that [a] variety of [the]
ostrich (Petise), may not be well adapted, and thus perish out; or, on the other hand, like Orpheus [a Galapagos bird], being favourable, ht be produced This requires [the] principle that the per circu to the adaptation of such circumstance, and therefore that death of species is a consequence (contrary to ould appear from America) of non-adaptation of circumstances”
The first part of the next extract has a sie is ofthat he had at this early date visions of the far-reaching character of the theory of evolution:--
”With belief of trans, we are lead to endeavour to discover CAUSES of change; the manner of adaptation (wish of parents??), instinct and structure becoeneration being condensation (I ieneration is ”condensed” to a shest organisation intelligibleMy theory would give zest to recent and fossil comparative anatomy; it would lead to the study of instincts, heredity, and mind-heredity, whole [of] metaphysics
”It would lead to closest exae in order to knoe have come fro and what prevents it--this, and direct exaht lead to laws of change, which would then be [the] uide our speculations”
The following two extracts have a si, as it contains the gerin of Species' (1st edition), page 490:-- ”There is a grandeur in this view of life, with its several powers, having been originally breathed into a few for on according to the fixed law of gravity, fro endless for evolved”)--
”Before the attraction of gravity discovered it reat a difficulty to account for the movement of all [planets]
by one law, as to account for each separate one; so to say that all mammalia were born from one stock, and since distributed by such
”Astronoht formerly have said that God fore-ordered each planet to move in its particular destiny In the same manner God orders each animal created with certain forms in certain countries, but how much more si to certain law, such are inevitable consequences--let anieneration, such will be their successors
”Let the powers of transportal be such, and so will be the foro at such a rate, so will be the number and distribution of the species!!”
The three next extracts are of miscellaneous interest:--
