you are ignorant
Hi traste,
Is there any fossil fish that showed thier parts slowly become parts of the amphibians?
You should really pay attention to what is being said to you.
You asked if there is a fossil showing a mix of fish and amphibian qualities. You asked that in response to a post that included BOTH fossils that you were looking for, yet you ignored it and asked for it again.
Fish to Amphibian: Tiktaalik
Since you probably won't look at the link, I'm going to copy paste the whole thing for you:
quote:
Tiktaalik represents an intermediate form between fish and amphibians. Unlike many previous, more fishlike transitional fossils, Tiktaalik's 'fins' have basic wrist bones and simple fingers, showing that they were weight bearing. Close examination of the joints show that although they probably were not used to walk, they were more than likely used to prop up the creature’s body, push up fashion. The bones of the fore fins show large muscle facets, suggesting that the fin was both muscular and had the ability to flex like a wrist joint. These wrist-like features would have helped anchor the creature to the bottom in fast moving current.
Also notable are the spiracles on the top of the head, which suggest the creature had primitive lungs as well as gills. This would have been useful in shallow water, where higher water temperature would lower oxygen content. This development may have led to the evolution of a more robust ribcage, a key evolutionary trait of land living creatures. The more robust ribcage of Tiktaalik would have helped support the animal’s body any time it ventured outside a fully aquatic habitat. Tiktaalik also lacked a characteristic that most fishes have - bony plates in the gill area that restrict lateral head movement. This makes Tiktaalik the earliest known fish to have a neck. This would give the creature more freedom in hunting prey either on land or in the shallows.
In Late Devonian vertebrate speciation, descendants of pelagic lobe-finned fish — like Eusthenopteron — exhibited a sequence of adaptations:
Panderichthys, suited to muddy shallows.
Tiktaalik with limb-like fins that could take it onto land.
Early tetrapods in weed-filled swamps, such as: Acanthostega which had feet with eight digits. Ichthyostega with limbs.
Descendants also included pelagic lobe-finned fish such as coelacanth species.Tiktaalik is a transitional fossil; it is to tetrapods what Archaeopteryx is to birds. While it may be that neither is ancestor to any living animal, they serve as proof that intermediates between very different types of vertebrates did once exist. The mixture of both fish and tetrapod characteristics found in Tiktaalik include these traits:
Fish:
fish gills
fish scales
"Fishapod":
half-fish, half-tetrapod limb bones and joints, including a functional wrist joint and radiating, fish-like fins instead of toes
half-fish, half-tetrapod ear region
Tetrapod:
tetrapod rib bones
tetrapod mobile neck
tetrapod lungs
Just a friendly reminder learn to analyse the things you read,instead of digesting them directly tried ti criticized.
Just a bit of advise, you shouldn't be so arrogant when you show such clear signs of being ignorant on this subject.

Re: you are ignorant
Hi traste,
Iam,paying that is why I was able to asked excellent question.
No you are not!
You asked for a fossil that was an intermediate form between fish and amphibians, you asked that question in a reply to a post that gave you the intermediate fossils that you were requesting.
Now, either you don't actually care to see the fossils or you don't think it represents an intermediate form. If you don't think it does represent an intermediate form, then explain why, and be specific.
What is it about that fossil that I linked for you that you feel does not represent an intermediate form between fish and amphibian?
And what is your evidence the lung fish?
Here is the fossil THAT YOU REQUESTED...again: Tiktaali
Here's the quote...again:

What a wishful speculations and boundless optimsm! Do you think your bounless optism would turned those primative fish into amphibians?
My optimism hopes to turn *you* into someone who actually reads links and provides an intelligent argument for or against the evidence.
But I'm slowly becoming pessimistic about that...
mammals become humans
I'm not going to reply to your ridiculous questions, however, are you saying that humans are not mammals?
Actually, Im notignorant of this subject butI guess you are.
Perhaps, but you have failed to show how and where I'm being ignorant.
