When it is so wrapped up, put it in the hot embers of a fire, how great or ardent soever it be, and having left it there as long as you will, you shall at last, at your taking it out of the fire, find the egg roasted hard, and as it were burnt, without any alteration, change, mutation, or so much as a calefaction of the sacred Pantagruelion.
Even on this ground it must be considered as a representative of a separate group of instances of the universal rule of systematic reversions. Of late the same mutation has occurred in the garden of C.A. White at Washington. The parent form in this case was the "Acme," of the ordinary weak and spreading habit of growth.
Even now that we have acquired some idea of the lapse of time, men are too apt to assume without proof that the geological record is so perfect that it would have afforded plain evidence of the mutation of species if they had really undergone mutation.
I shall consider the limits between fluctuation and mutation only, and attempt to set forth an adequate idea of the principles of the first as far as they touch these limits.
Just at present it seems premature to believe that all evolution is by mutation, although quite possibly some of it is. The main apparent advantage of mutation is that it hastens the time in which a new species may arise. There are certain difficulties which run back into the problem, and which must first be reasonably solved before a clear understanding of the idea of evolution is possible.
Dalgard withdrew his hand from the beads. Through the years the Astran colonists had come to recognize the virtues of patience. Perhaps the mutation had begun before they left their native world.
Lindley and other writers, on horticultural theory and practice assert that a large amount of nourishment tends to produce double flowers, while a culture under normal conditions, even if the plants are very strong and healthy, has no such effect. But even here it remains doubtful whether it applies to the period before or after the internal mutation.
We have not distinguished the change of figure, the alteration of position, the mutation of texture, to which matter is liable, from its annihilation, which is impossible; we have falsely concluded, that matter Was not a necessary being that it commenced to exist that this existence was derived from that which possessed nothing in common with itself that that which was not substance, could give birth to that which is.
I think, myself, until some one imagines giving an eight-o'clock dinner; then all the informalities will go, and the whole train of evils which such a dinner connotes will rush in. The cottages themselves are of several sorts, and some still exist in the earlier stages of mutation from the fishermen's and farmers' houses which formed their germ.
Birds are adapted in their whole organization for flight, the structure of the wing, of the sternum, breast muscles, legs, etc., are all co-ordinated for this end. But how do we know that feathers in their origin were connected with flight? It seems equally probable that feathers arose as a mutation in place of scales in a reptile, and the feathers were then adapted for flight.
