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."

This can only fuel the cult of Raptor Jesus to unimaginable new heights.

More interesting than the article is that I now know there is such a thing as a serpentarium. Everywhere I've lived, and in all the movies I've watched, they've just been called 'reptile zoo' or something similar.

I imagine people go into a serpentarium and the lights are low. Everyone sits down, reclines their seat back and stares upward. Then the lights come up to reveal thousands of serpents suspended from the ceiling, writhing around. People ooh and aah.

Sounds awesome.

Serpentarium sounds like the title of a song Metallica should write.

Immaculate Conception doesn't mean virgin birth

[BadAnalogyGuy]

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.

This must be the first time anyone has ever misinterpreted content from the Bible.

Immaculate Conception?

[Imnimo]

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.

And the chromosomal oddity is...

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.

sssssst

Pedantic nit...

Asexual reproduction isn't the same as virgin birth.

For all we know, that snake is a slut.

That is so cool.

Chromosomal Oddity

[cappp]

The summary skips out on the interesting detail there

The mother in question gave birth to not one, but two snake litters of all-female snakes with WW-chromosomes. Male snake cells have two Z chromosomes, while female snakes have a Z and a W. This is the first time a reptile has been seen with two W chromosomes, something thought peculiar to fish and amphibians. The snakes' litters also retained the mother's rare genetic coloring

Also direct links to the study are here and here(pdf). The paper is "Evidence for viable, non-clonal but fatherless Boa constrictors" by Warren Booth, Daniel H. Johnson, Sharon Moore, Coby Schal, and Edward L. Vargo.

I'm not really up on Christian doctrine, but from reading the rest of this discussion, I believe you are referring to Raptor Jesus.
