Theories upset.

From BBC News

For the first time, frogs have been seen giving birth to tadpoles.

Most frogs lay eggs and although some species give birth to froglets, newborn tadpoles are new to science.

Dr Jim McGuire from the University of California, Berkeley, actually thought he was holding a male frog the first time he witnessed a birth.

Nurse: Sir, please put your signature here, on the 2nd line: FATHER 😉

Well. It isn’t quite that bad, is it? It’s just that

Nearly all the world’s 6,000 frog species use external fertilisation: the female lays eggs during mating, while the male releases sperm to fertilise them.

This new frog is one of only 10 or 12 species that has evolved internal fertilization, and of those, it is the only one that gives birth to tadpoles, as opposed to froglets or laying fertilized eggs.”

So maybe it is not necessarily that the others couldn’t do it (apparently this amphibian can). But they don’t do it, for various reasons.

No one currently knows how the tadpoles’ parents manage to do it.

It’s not what we know about the evolution of life on Earth but what we didn’t know that will sink Darwin’s Tree of Life.

Here’s the abstract:

We describe a new species of fanged frog (Limnonectes larvaepartus) that is unique among anurans in having both internal fertilization and birth of tadpoles. The new species is endemic to Sulawesi Island, Indonesia. This is the fourth valid species of Limnonectes described from Sulawesi despite that the radiation includes at least 15 species and possibly many more. Fewer than a dozen of the 6455 species of frogs in the world are known to have internal fertilization, and of these, all but the new species either deposit fertilized eggs or give birth to froglets.

    Obviously, this is further proof of evolution. I’m sure that whatever is discovered about this viviparous frog and its fangs will eventually be rationalized within Darwin’s theory. You just have to have faith. 😉

    Good judgement about a good thread here.
    right on about it not being that the others couldn’t do likewise. its likely all frogs have this ability if some threshold is crossed.
    They simply have the reproductive ability as they need it.
    its no big deal about reproductive differences.
    Don’t classify creatures based on it.
    This is why this YEC insists marsupials are only placental creatures which developed marsupial traits upon migration to certain areas for certain reasons.
    this is why there is such likeness between marsupial lions, wolves, moles, etc as with placental ones.
    Not because of convergent evolution myths but because THEY ARE THE SAME CRITTERS. Just with a wee pouch.

    Everybody should youtube the last marsupial wolf and decide for yourself if that is just a wolf with a pouch or a flexible wombat as evos say.

    This reminds me of the frogs that swallow the eggs, and reduces it’s stomach acid, and doesn’t eat until the eggs hatch and the frogs are born.
    I guess one day a frog was hungry and ate it’s own eggs, but it lost it’s appetite, and another miracle of evolution occurred.
