And equally interesting, indeed more important from the point of view as to the real meaning and nature of fertilisation, is the mode in which the parthenogenesis of the frog is set going, namely, by a mere prick of the surface film of the ripe egg!
These were Costake Theriade, of Rumania, a tall, dark, high-browed thinker, who was engaged in devising ways to extract and recover interatomic energy; and Sir Wilfred Athelstone, whose specialty was bio-chemistry, and who was said to have produced amazing results in artificial parthenogenesis and the production of new species.
The chief point of novelty in M. Bataillon's discovery is that we have now an experimental demonstration of parthenogenesis in a vertebrate animal, and in one so highly organised as the frog.
"Have you no kind of life where it is possible?" asked Zava. "Why, yes some low forms, of course." "How low or how high, rather?" "Well there are some rather high forms of insect life in which it occurs. Parthenogenesis, we call it that means virgin birth." She could not follow him. "BIRTH, we know, of course; but what is VIRGIN?"
But let us return to that special form of her resistless intervention that we find in parthenogenesis. And we shall do well to remember that, remote as the world may seem in which these problems confront us, they do indeed yet concern ourselves very nearly.
Unquestionably there will be great volcanic spasms, but they will not prevent the occupation of the broadening areas of land which will not be thus affected." "Upon these lands," exclaimed Sir Wilfrid Athelstone, in a loud voice, "I will develop life from the barren minerals of the crust. The age of chemical parthenogenesis will then have dawned upon the earth, and man will have become a creator."
So, also, the broad distinction between reproduction by seeds or ova and propagation by buds, though perfect in some of the lowest forms of life, becomes evanescent in others; and even the most absolute law we know in the physiology of genuine reproduction that of sexual cooperation has its exceptions in both kingdoms in parthenogenesis, to which in the vegetable kingdom a most curious and intimate series of gradations leads.
In many insects and other Arthropods which are not parthenogenetic the male has been found to possess fewer chromosomes than the female. The female forms, as in the above cases of parthenogenesis, only gametes of one kind each with N chromosomes, but the male forms gametes of two sorts, one with N chromosomes, the other with N-l or N-2 chromosomes.
XXXIII, A: Dragonfight = wrestling match = winning of the offered king’s daughter = rape of the women = rape of fire = deluge. XL, A: Incest motive = Potiphar motive. XLV, A: Sodomy = substitution = rape = parthenogenesis = marriage of mortal with the immortal = seduction = adultery = incest = love = embraces of the first parents = wrestling match.
Not only did our mediæval ancestors believe all sorts of fancies as to the propagation of lower animals and plants, but they were quite prepared to accept stories as to reproduction in the case of higher animals, and even in mankind, by irregular methods, such as parthenogenesis, or the defect of an ordinary male parent.
