The Weird Things That Some Bacteria Eat

Posted December 02, 2012 12:17 PM

From mental_floss:

You probably know that bacteria are everywhere, but you might not be aware of just how many ways bacteria help us, just by eating. For example, Geobacter sulfurreducens can be used to clean up toxic waste, because it is able to eat energy produced by unstable uranium particles. When the bacteria are finished, the end result is a solid, stable form of uranium that is much easier to clean up. In some cases, a bacterium's diet is amazingly specific. One strain of Wolbachia, for example, only eats the gonads of the Aedes aegypti mosquito. While it doesn't destroy the reproductive organ, it does alter the course of reproduction in a way that prevents the mosquito from carrying the deadly Dengue virus.

Even more so than Creation. Makes me think Creation is easier to believe in. Else how did a Bombardier Beetle survive to evolve its chemical explosive defense mechanism? Seems like the trial-and-error method, with the best effects surviving, would have killed off the first beetle that tried it, and any subsequent strains.

This is an old discredited arguement check out

On the contrary, I DO understand (and did before) how the bombardier beetle's systems function.

And, DISCREDITED? I think not. What you offered is a complex series of steps which MIGHT have happened, which PROBABLY happened, which naturally COULD HAVE happened (all words used in the microevolutionary steps elucidated in the text).

Anyone see it happen? No? Anyone prove it? Anyone repeat it? (OK, I admit that last one is unfair. No one has recreated one of these genetic manipulations, so, no one has this repeated this part, either. OTOH, if this WAS spontaneous, why should it have to require a genetic manipulation by humans to make it happen?). So, your belief in evolution is just that. Same old discredited FAITH!

You choose what you put your faith in. I chose mine. And all the arguments you've put forth give me no reason to make a new choice.

There's a carton of milk sitting on the bench near me now.

I don't know how it got there but I can create a plausible train of probable explanations (none of which I witnessed personally) Something like Farmer milked cows in Gippsland, milk was processed at Timboon, transported by road to Safeway, bought by wife etc.

Somehow this train of admitted guesses is more believable than saying "Pixies put it there".

Certainty is not a virtue, admitting that something could/might/may have happened and then trying to find out what actually did happen is far more intellectually honest.

We agree on one thing.

"Pixies put it there"

God ain't "pixies".
