As regards the latter, no one is likely to maintain that an act of direct creation would include the production of an organ of some slight and obscure utility to the embryo and useless in later life. The strong probability is that this gland belongs in the same category with other embryonic survivals yet to be pointed out.
Obviously this aquatic organisation has no reference to the future life of the animal, nor has it any adaptation to its embryonic condition; it has solely reference to ancestral adaptations, it repeats a phase in the development of its progenitors."
During nine years, as foretold by the Báb Himself, swiftly, mysteriously and irresistibly the embryonic Faith conceived by Him had been developing until, at the fixed hour, the burden of the promised Cause of God was cast amidst the gloom and agony of the Síyáh-Chál of Ṭihrán. “Behold,” Bahá’u’lláh Himself, years later, testified, in refutation of the claims of those who had rejected the validity of His mission following so closely upon that of the Báb, “how immediately upon the completion of the ninth year of this wondrous, this most holy and merciful Dispensation, the requisite number of pure, of wholly consecrated and sanctified souls has been most secretly consummated.” “That so brief an interval,” He, moreover has asserted, “should have separated this most mighty and wondrous Revelation from Mine own previous Manifestation is a secret that no man can unravel, and a mystery such as no mind can fathom.
Only a rudiment of a fourth digit has been found in the embryonic wing, not, as might be expected, rudiments of five digits of which two disappear. The metacarpals are free, not united as in the adult, and there are separate distal carpals, which in the adult are united with the metacarpals.
And all day, from apartments below, from rooms above, came an endless banging, shrieking and caterwauling from embryonic tenori and virtuosi, such as, within a month, would have cured all but the most persistent music-lovers of any further desire for the expression of that abstract art. Ivan was of the most persistent.
By a number of important embryonic adaptations, the chief of which is the formation of an extensive food-yelk, the original course of the development of the vascular system has been so much falsified and curtailed in the higher Vertebrates that little or nothing now remains in their embryology of some of the principal phylogenetic features.
It is claimed that the whole history of evolution is briefly repeated in the early stages of embryonic life. W. B. Scott, in the "Theory of Evolution," says, "Thirty years ago, the recapitulation theory was well nigh universally accepted. Nowadays it is very seriously questioned, and by some high authorities is altogether denied."
Without much doubt the Poduras are the lowest of the six-footed insects. They are more embryonic in their appearance than others, as seen in the large size of the head compared with the rest of the body, the large, clumsy legs, and the equality in the size of the several segments composing the body.
If we now look back on all the remarkable features we have encountered in the structure and the embryonic development of the Amphioxus and the Ascidia, and compare them with the features of man's embryonic development which we have previously studied, it will be clear that I have not exaggerated the importance of these very interesting animals.
Myth-making activity, which we have studied in the child and in primitive man, is the embryonic form whence arise by a slow evolution religious creations gross or refined; esthetic development, which is a fallen, impoverished mythology; the fantastic conceptions of the world that may little by little become scientific conceptions, with, however, an irreducible residuum of hypotheses.
