Teamwork Between Shining Bacteria and Squids Evolved?
by Brian Thomas, M.S.*
Certain strains of bacteria, named Vibrio, can establish a mutually beneficial link with a squid by a single gene switch, according to researchers at the University of Wisconsin.1 Could this precisely specified biochemistry really have evolved from the comparatively simple switching-on of just one gene, as their study suggests?
Vibrio bacteria have a well-orchestrated capacity to interact with specialized tissue found on the bobtail squid and the Japanese pinecone fish.2 A biochemical conversation takes place between animal and bacteria whereby the animals specialized tissue secretes a gummy substance that makes a good home for the bacteria. If the bacteria possess the correct genetic switch, it is turned on by the hosts specific chemistry, enabling the bacteria to secrete a special biofilm. Only in this environment do the bacteria begin to glow. The cold light emitted by the bacteria-infected light organ attracts prey for the animal, thus establishing a symbiotic relationship between the bacteria and their host.3
The researchers hypothesized that by encoding a regulator and not an effector that interacts directly with the host, a single gene can contribute to the evolution of host specificity by switching 'on' pre-existing capabilities for interaction with animal tissue.4 But where did the pre-existing capabilities come from? The genetic switch is a single necessary component of a long list of parts, some of which must interact directly with the host, and all of which must be present for the glow to show.
The newly-identified switch must properly link with molecules that specifically interact between the bacteria and the microbe, and these communicative chemicals are only useful in the context of fully-operable organisms. The facts are that the bacteria can manufacture biofilm and light, and the animal can build its pouch-shaped light organ, and these depend on many fully-formed parts.
The most plain, obvious, and scientific inference from these facts is that these systems came about by some plan. Further, the identity of this Planner as One who is both wise and capable is consistent with the omniscient biblical God.

I think that retains the concept of a "designer" ~ and is consistent with other "tank dumps" we've had.
LOL! Given your PM, I assume you mean IBTP (not IPTP), right? Or is your acronym evolving :o)
“Further, the identity of this Planner as One who is both wise and capable is consistent with the omniscient biblical God.”
You obviously have no biology background. Please read some books on it, or have you burned them already?
Burned before reading.
Do any of these guys actually do any original science?
I can imagine that type of work must get boring when they know the outcome to every line of enquiry is going to be ‘the biblical god did it’.
I would explain it to them, but it would be a wasted effort.
why don;’t you explain it here- Enlighten us oh wise one
I have no problem with biology. What I have a problem with is a med-school dropout turned amateur naturalist, who presumed to rewrite the entire history of biology based on some minor variations between finches.
[[I can imagine that type of work must get boring when they know the outcome to every line of enquiry is going to be the biblical god did it.]]
As boring as the same type of work where the macroevolutionists ‘know’ the outcome to every line of enquiry is goign to be ‘nature didit’ despite the fact that in order for nature to have ‘doneit’ it would take acts of biological, mathematical, chemical and natural violations? Interesting.
Thanks for the ping!
Your correction is accurate!

Like my new tag line?

Puts a smile on my face every time I read it.
