Ms. Lindskoog (Journal ASA,
March, 1977) apparently has some inaccurate views of the biology of
reproduction. First of all, parthenogenesis does involve some aspects of
fertilization. Fertilization stimulates the egg to develop; without
fertilization, there is no development. A point that must be considered is that
spermatozoa are not the only agents capable of triggering development.
Mechanical stimulation of the egg can trigger development, although in higher
animals this does not proceed to embryo formation. In the instances with which I
am familiar of parthenogenesis in vertebrates, the mechanism appears to be
either the failure of the first cleavage to complete or the recombination of one
of the polar bodies with the egg cell. Either way, parthenogenesis in
vertebrates results in diploid individuals. Of interest to me is that the
offspring produced parthenogenetically are XX in chromosome constitution. For
birds such as the turkey, which have been successfully produced in this fashion,
the result would be a male. For mammals, with the opposite means of sex
determination, the result would, in all cases, be a female. Historically, Jesus
was a man. Parthenogenesis as we understand it today could not have resulted in
his birth.
In answer to another point, Man has 46 rather than 48 chromosomes. A chromosome
smear was miscounted and the figure of 48 appeared in scientific literature of
the late 1940's and early 1950's.
Inasmuch as Jesus was truly God and truly man, it seems reasonable to assume
that he was not only outwardly human, but genetically human. Therefore I believe
that Jesus was diploid in chromosome number and did in fact have all the organs
of a functional male. It seems rather farfetched to me to believe that Jesus
produced sperm prior to his appearance on earth as a true man.
In conclusion, I feel there is no biologically satisfactory explanation for the
virgin birth. As a Christian, it is reasonable for me to believe that Jesus'
birth occurred as reported in Matthew without necessarily requiring a biological
explanation for it. As biological knowledge expands, an explanation may be
forthcoming, but for now faith suffices.
