“Species” is a description that is grossly misrepresented, IMO. It ‘suggests’ that a new “species” is something other than a new variety of an organism in the same taxonomic family. As Darwin himself observed.....his finches were all varieties of finches.....the tortoises were still clearly tortoises and the iguanas were marine adapted iguanas. What are we missing here? "Species" did not mean a new 'kind' of animal or bird...only a different "species" of the same 'kind' of animal or bird. Real science as opposed to theoretical science 'knows' this.
How many times must the law of monophy be explained to you, before you'll let go of this strawman that's been addressed a thousand times already?
So when did the taxonomy rankings begin?
The second living things reproduced with modification.
When did all creatures reach a point where science says that they belong to a certain family?
The second living things reproduced with modification.
It seems to me that anything before that point is all guesswork...
No. It's how reproduction works.
.but it must fit in with the beloved theory or it will be thrown out as invalid.
The evidence must fit, yes.
If we see a population of finches evolve into non-finches, then evolution is falsified as evolution can't handle violations of the law of monopy.
Please learn the model you are so hellbend on arguing against, before trying to argue against it.
If a construction company was contracted to build a number of structures in a city and they used different designs in their constructions but used the same architect and supplier for all their materials.... are the buildings related because they use the same designer and the same materials in different structures? Or is it that they have the same builder?
1. buildings don't reproduce with inheritability of traits and modification, nore are they organic. As such, they are a false analogy to biological reproducing organisms as they aren't subject to the laws and processes of bio-chemistry. This is the equivalent of arguing against gravity "because hammers don't fall down in the international spacestation".
2. That wouldn't produce nested hierarchies. My Xeon PC doesn't have an inactive remnant of a 4-86 cpy in it. But chickens do have inactive DNA to build teeth.
And here he is again...that phantom "common ancestor"...no mention of what it could have been...only that it has to have existed for that tree to be included in any science textbook. Without that trunk...there is no tree.....no branches...no nothing.
I've already addressed this and explained to you how we don't need to be able to
identify the common ancestor to know that there was one.
Yet another mistake that you refuse to correct.
Two orphans from unknown parents can be determined to be siblings, without knowing who the parents were. All you need is the DNA of both siblings.
As I told you already: DNA is a great tool that allows us to establish relationships / level of relatedness.
Only one of many, btw. The conclusions from DNA can be cross referenced with all the others. And it fits. Every. Single. Time.
According to all I have read......everything on your tree here is assumed...not proven in any real way.
Then you must not have read the reference YOU YOURSELF have posted about what phylogenetic trees are. Remember? Your quote said that they are created BASED ON GENETIC AND MORPHOLOGICAL
DATA. Not based on assumptions. Based DATA.
Data from fully sequenced genomes, comparative anatomy of extant species, comparative anatomy of fossils, comparative anatomy of fossils and extant species, geographic distribution of species, geographic distribution of fossils, geographic distribution of genetic markers, etc etc etc etc.
These are facts leading to a conclusion. Not assumptions.
Just like there are no assumptions in a DNA paternity test. It's just comparing DNA, tracing markers and determining ancestry.
Your tree is a construction of imagination
No. It's a representation of data. As the reference YOU YOURSELF HAVE POSTED cleary explained.
Such as?
you honestly believe that any lines of evidence supporting common ancestry are independent?
That is a fact, yes.
You can draw a tree based on fully sequenced genomes.
You can draw a tree based on tracking a single genetic marker.
You can draw a tree based on comparative anatomy.
You can draw a tree based on tracking a single bone (like an inner ear bone)
etc
All these are independent studies.
And these trees all match with one another.
They didn't have to match. But they do.
Chickens didn't have to have inactive DNA to build teeth. But they do.
Humans and chimps didn't both have to have a broken (in the exact same manner) GULO gene. But they do.
The fish-tetrapod tiktaalik didn't have to be found in 370 million year old rock in a specific location in canada. But it was.
All these are independent lines of evidence that all converge on the exact same answer.
Denial isn't going to change that.
They are all supplied and backed by evolutionists who must of necessity all agree on the basics, even if they differ on the details (which they often do.)
Yes, in science it is a necessity to follow the evidence.
And since all evidence leads to evolution, all settle on evolution.
To disagree would see them laughed out of the hallowed halls of learning....
Yep. Just like a Stork Theorist would be laughed out of the embryology department, or how a flat earther or a geocentrist would be laughed out as well.
There comes a point where denial is no longer defendable.
you only have to listen to the likes of Dawkins or Coyne to see what I mean. Preaching to the converted doesn't really count.
Or Ken Miller or Francis Collins.
Both devout christians, btw.
I could probably say the same about you....if you read the article without the rose colored glasses, it is full of speculation and assumptions about what they want to believe is true about Tiktaalik. If it is what they predicted, when why the surprise at what they found?
What they actually predicted was spot on: the location, the age and the fact that it would have BOTH fish and tetrapod traits.
The stuff they found surprising / exciting were about details where they had certain expectations / informed guesses. None of these invalidates the enormous success of their prediction. The prediction being the location, age and that it would feature fish-tetrapod transitional traits. And that is exactly what Tiktaalik is: a fishy tetrpod, found in exactly the location and rock they predicted it would be in.
This is the elephant in the room that you are hellbend on ignoring, by trying to distract into details that are irrelevant to this huge point.
How did they know where to look?
How did they know what age it would be?
How did they know about the transitional fish-tetrpod features it would have?
If evolution is so wrong, why did they find ANYTHING AT ALL? Let alone something that matches their prediction so amazingly well?
Do you not know the difference between guesses and facts? If they went looking for a creature that fitted their expectations, how could they not interpret what they found to fit the bill?
It did fit the bill. It's a fishy-tetrapod of the correct age in the correct location.
See this is what I meant when I said that you are so focussing on the irrelevant detail / pixel, that you're completely losing track of the bigger picture.
They didn't predict an entire body plan, right down to the smallest bone structures.
Instead, they predicted a mix of fish and tetrapod traits. And that's exactly what they found.
Every time there is some grand announcement about another "find" that supports evolution, we see that the excitement does not match the actuality of the find...only the guesswork of what they imply....its just a clever illusion IMO.
Still in denial I see.
Once more:
They predicted the age, the location and that it would have a mix of fish and tetrapod traits.
How does Tiktaalik not match that prediction?
