In much the same way the mitochondria is thought to have come into existance, it has been shown that a species of nudibranch, Elysia chlorotica, has acquired genes from the algae that it feeds on in order to produce new chlorophyll A. Elysia spp. nudibranchs as well as many coral, soft coral, anemone, flatworm and giant clams species are known to take in photosynthetic dinoflagellates or diatoms without digeting them in order to make use of the photosynthetic products of the symbionts. The most interesting of these is the Tridacnid clam system where a specialised vascular-like transport system is involved to transport the dinoflagellates around the mantle tissue. This new discovery takes "animal photosynthesis" to a whole new level. Instead of controlling the photosynthesis of the endosymbiont, these animals simply remove the chloroplasts from the prey and produce their own chlorophyll A. This could have huge implications as far as genetic enginerring and potentially for agriculture. I would like to find the original paper to get a bit more detail on the processes.

Check out the wired article here.

Would we see a mammal by the water's edge "suddenly" start breathing underwater(w/camera effect of course)?

Thanks a lot!!!!

Creationists should use this. They should claim Evolution can't explain it, and conclude that Yahweh must have done it.

What they don't seem to realize is that we should find thousands and thousands of examples like this. Ostriches should have solid bones. Bats should have spongy bones and feathers.

Every weird mixture of traits can be easily explained by transitions, common ancestry or convergent evolution.

This slug can't. Nobody would claim it could.

Thanks a lo, firechild, for this awesome exception!

Would it not have made sense for the creator to just put the chloroplasts into the animal from the beginning as well? It does not make sense for an animal to be able to produce a photosynthetic pigment (Chlorophyll A in this case) but have nowhere for it to function. Chloroplasts are the vital missing ingredient that prevent the animal from being entirely autotrophic. Maybe this is a step that will be added later in the evolutionary line, maybe it won't. closer study of the genome will be necessary to demonstrate the DNA has in fact come from the particular species of algae the animal feeds on.  Then we should no doubt see a clear example of evolution. Also, if a creator had thought of this design, why would its use not be more prevalent in the animal kingdom? It's a great design and I would think a creator would make much more use of it.

That reminds me of a discussion i had with timbrx in the thread Does creationism predict gaps?

timbrx

timbrx
In a created world we would expect to find different kinds of animals
Er... Why? Why not a single self-sufficient kind? Why not just us and a solar chemical process to feed us?

Because what we see is what we have.
Then take back your claim that "we would expect". Post hoc stories don't qualify as "expectations".

We do expect. A lot. The ToE really predicts. A lot. The Tiktaalik and the Aardonyx Celestæ fit smoothly in our expectations.

We have a phylogenetic tree. Everything we find must fit, or the tree falls down.

You have nothing, and nothing falls down. Anything we find will meet your explanation: "
Because what we see is what we have."

We expect much, and we don't get disappointed.
You expect nothing, and you don't get disappointed.

Thus, your lack of disappointment is worth much less.
