That is silly.
There is no scientific, religious, or any basis at all to believe in immaculate conception, since human desire sex.
And even if it did happen, it can happen naturally, just as all organisms reproduced asexually in the past.
{...
Asexual reproduction is found in nearly half of the animal phyla.
[37] Parthenogenesis occurs in the
hammerhead shark[38] and the
blacktip shark.
[39] In both cases, the sharks had reached sexual maturity in captivity in the absence of males, and in both cases the offspring were shown to be genetically identical to the mothers. The
New Mexico whiptail is another example.
Some reptiles use the
ZW sex-determination system, which produces either males (with ZZ sex chromosomes) or females (with ZW or WW sex chromosomes). Until 2010, it was thought that the ZW chromosome system used by reptiles was incapable of producing viable WW offspring, but a (ZW) female
boa constrictor was discovered to have produced viable female offspring with WW chromosomes.
[40] The female boa could have chosen any number of male partners (and had successfully in the past) but on this occasion she reproduced asexually, creating 22 female babies with WW sex-chromosomes.
Polyembryony is a widespread form of asexual reproduction in animals, whereby the fertilized egg or a later stage of embryonic development splits to form genetically identical clones. Within animals, this phenomenon has been best studied in the parasitic
Hymenoptera. In the
nine-banded armadillos, this process is obligatory and usually gives rise to genetically identical quadruplets. In other mammals,
monozygotic twinning has no apparent genetic basis, though its occurrence is common. There are at least 10 million identical human twins and triplets in the world today.
