RE: evolutionary evidence yet again makes the news
I don't worry about what a creationist says or thinks. In a debate, the task is to win the audience. Pointing out the hypocrisy of harping on qualifiers when their pet "theory" is certainly unevidenced is a good riposte.

RE: evolutionary evidence yet again makes the news
What came first the swim bladder or the primitive lung? I know that this has always been highly debated by evolutionary scientists. Much to what was previously believed, I think that the evidence from what I've read is coming down on the the side of the swim bladder as being an exaptation of the primitive lung?

"The coelacanth, an elusive deep-sea dweller long thought extinct, had another item added Tuesday to an already-long list of unusual physical traits: an obsolete lung lurking in its abdomen.

Similar to the human appendix, the organ was likely rendered defunct by evolution, researchers noted in the journal Nature Communications.

Like all fish, today's coelacanths -- referred to as "living fossils" -- use gills to extract oxygen from the water they live in.

But millions of years ago, coelacanth ancestors probably breathed using the lung, the team concluded.

"By the Mesozoic Era, adaptation of some coelacanths to deep marine water, an environment with very low variations of oxygen pressure, may have triggered the total loss of pulmonary respiration," co-author Paulo Brito of the Rio de Janeiro State University told AFP.

This could explain how it survived the extinction event 66 million years ago that wiped all non-avian dinosaurs and most other life from Earth -- and probably those coelacanths inhabiting shallow waters, he said.

It would also account for "the marked reduction" of the lung into its shrivelled, present-day form, Brito said by email.



- 'Lazarus' fish -



Coelacanth fossils have been dated to about 400 million years ago, and the fish was thought to have died out towards the end of the Mesozoic era, which stretched from about 250 to 66 million years ago.

But then one was caught off the South African coast in 1938, earning the coelacanth the title of "Lazarus taxon" -- a group of animals "resurrected" from extinction.

A few other individuals have been found since, as well as members of a cousin species off the coast of Indonesia, but the coelacanth is considered endangered.

It is a queer fish in many ways.

Key among its quirks, it has paired, "lobe-shaped" fins which move in an alternating pattern similar to a four-limbed land animal -- sparking speculation that it may have been a member of a group of fish that first crawled onto land to evolve into animals with legs.

The grey-brown fish can grow up to two metres (6.5 feet) in length, weigh as much as 91 kilos (200 pounds), and may live up to 60 years.

It has a hollow, liquid-filled spine, enamel-capped teeth, and a hinged jaw that allows it to open its mouth wide to swallow larger prey.

Little is known about how they live, what they eat, how they reproduce, or how many of them are left.

The new discovery was based on dissections and scans of infant and adult coelacanth samples, as well as 3D reconstructions, said Brito.

The team found that the disfunctional lung is proportionally much larger in the coelacanth embryo than the adult, meaning that growth of the organ slows as the fish gets older."

Love this stuff....no worries theists, nothing to see here Laugh out load

I just posted this link at a forum I frequent where one of the guys posts all this scientific discovery information and then folds in some religious/spiritual twaddle. Fucking apologist for the RCC, to boot. I've jabbed him many times over that.

Nature and the real world are just so awesome, why would someone make up lies about how it works? Oh yeah, someone with an agenda for gaining power over others...

Those who seek power over others quickly learn that fear makes that happen...and as you know, fear is good business....nothing fills the coffer plates like a good sermon based on fear....repent my brother, quickly, the lord returns soon...here pass the plate to your left....come brothers and sisters, satan is trying to prevent you from giving...dont let him win....reject eternity in hell by embracing the lawd jesus christ....a fool has in his heart declared there is no god....there will be no fools in heaven....

If there really was a hell, that's where the fools would be. Obviously my definition of fool is a little different from that espoused in that nasty work of fiction. Don't the xtians realize that hell was made up in the NT? Facepalm You may have seen this: https://www.futurechurch.org/brief-histo...lic-church

I cherry-picked this little gem for your viewing pleasure:

1095-Pope Urban II had priests [sic] wives sold into slavery, children were abandoned.

Nice little religion you got there, Roman Catholics. To think, I used to be one, but that was through indoctrination. I don't know how those people sleep at night. Holy men?!? Dodgy
