Immaculate Conception In a Boa Constrictor

crudmonkey writes "Researchers have discovered a biological shocker: female boa constrictors are capable of giving birth asexually. But the surprise doesn't end there. The study in Biology Letters found that boa babies produced through this asexual reproduction — also known as parthenogenesis — sport a chromosomal oddity that researchers thought was impossible in reptiles. While researchers admit that the female in the study may have been a genetic freak, they say the findings should press researchers to re-think reptile reproduction. Virgin birth among reptiles, especially primitive ones like boas, they argue may be far commoner than ever expected."

  1. Immaculate Conception doesn't mean virgin birth by BadAnalogyGuy · · Score: 5, Informative

    A lot of people make the mistake of equating "Immaculate Conception" to the virgin birth of Jesus. Actually, it refers to the birth of Mary (mother of Jesus) being born without Original Sin. What the author is referring to is the Annunciation, which is the virgin conception of Jesus within Mary.

  2. Immaculate Conception? by Imnimo · · Score: 5, Informative

    This is not what Immaculate Conception means. The Immaculate Conception is the conception of Mary, not of Jesus, with the idea being that Mary is conceived without original sin so as to make her a proper vessel for Jesus. Then again, since snakes don't have original sin, maybe every snake conception is immaculate.

    Two WW chromosomes. In mammals, we have X and Y chromosomes to determine sex—but in reptiles, fish, and of course birds, the norm for a female is ZW, and the norm for a male is ZZ. This brought to you by Tilde R: Helping Those Who Hate RTFA.
