Nice input Professor Shubin. Your inputs is of great help to us.

[DNAunion]

"chickens tears and humans tears are almost exactly the same"

I don't suppose you'd mind supporting that assertion.

[squirrelroks]

Evolution is not "fish turning into man" but how earlier organisms developed and diversified over time by natural selection. The problem with the arguments today is that people compare modern species to each other. For example, the modern ape to the modern human. But in reality the ancient form of apes would be more similar to the ancient form of humans, not the forms today. Evolution does not dispute religion, and I, a christian, believe in the validity of evolution. Its a proven theory.

[thetraceur123]

@squirrelroks Agreed. Same here, also a Christian and very pro-science.

[DragonzFyre99]

Evolution does not threaten faith. One should never confuse faith with religion, they are mutually exclusive. One does not require religion to have faith. Doctrine is not faith, it is a tool designed to instill fear and cow the masses into relinquishing intelligent and independent thought and to line the pockets of its prophets with the wealth of its flock. Faith does not require monetary contribution or indoctrination. Evolution is definable, quantifiable, and verifiable. Enough said.

religious people suffer from temporal lobe epileptic disease and need medical help....not respect for there delusional, hallucinatory mindless babble.

its not real people....get some help and shut the fuck up!

religion is the reason for most of the worlds troubles right now and we would all be better off without any of it.

we know whats right from wrong and we dont need a "sky dictator" to tell us.

child molesters, divisionists, separatists, terrorists........ALL the domain of religionists.

[zencat999]

no more b u l l s h i t yaaaAAAAAAAAAAAA SCIENCE!

[realhomosapiens]

Hmmm, how major transformation can happen? from one of those weird cambrian marine creatures to a fish to a human is a huge, an insurmountable transformation Neil, you`ve got to revise your scientific myth, sorry your theory...jajajajaja

[NestorSanchez3D]

@realhomosapiens An insurmountable transformation requires insurmountable amount of time. Oh wait, this concept and the evidence that supports it contradicts your 6,000 year old Earth indoctrination... what will do besides go into denial? Any evidence on to pull the balance on your favor?

[realhomosapiens]

@NestorSanchez3D

So if a frog turns into a Prince in an instant is a fairy tale, but if a fish turns into a man of course givin enough time, that is science, and if it´s taught by N. Shubin, there is nothing to be doubted, ...nooope my friend that story of a fish turning into a man is the greatest stupidity I have ever heard of, unfortunately it is taught as if it were science...in short, it´s a fairy tale, a scientific fairy tale neverthe less a fairy tale...deal with it

[NestorSanchez3D]

@realhomosapiens EVIDENCE, tons of it. Lots of data from many different disciplines (geology, paleontology, biology, archeology, chemistry, tectonics, forensics and a lot of others) all pointing out to the same direction from multiple angles and starting points.

Is just the most plausibleRATIONAL conclusion, the most obvious one that is supported by the data. If you can prove a better NATURAL, UNIVERSALLY VERIFIABLE explanation, that does not contradict the all the evidence

[realhomosapiens]

@NestorSanchez3D

So believing that my great-great-great-grandpa was a fish, it´s RATIONAL, so basically if a frog turns into a Prince by a kiss in an instant that´s a tale, but if a fish turns into a man by means of evolution in millions of years that is not a tale but science, right? do you want me to laugh at you or what?

[DNAunion]

@realhomosapiens

"if a frog turns into a Prince by a kiss in an instant that´s a tale, "

Kent, how are you posting on the Internet from behind bars???

[realhomosapiens]

@DNAunion

Hi DNA, long time no see you...Have you ever heard of a frog turning into a prince in an instant? well, except for the time and other issues the story is the very same one...frog produces only frogs but your scientific mythology asserts that given enough time plus some random mutations one of those weird cambrian marine creatures could ever turn or evolve into humans, let alone all the creatures along the road and that is a long, long scientific tale taught as science, period.

[DNAunion]

@realhomosapiens

"Have you ever heard of a frog turning into a prince in an instant?"

Which has nothing to do with evolution.

Once we eliminate the strawman part of your "argument", the "logic" seems to be that if X cannot happen instantly, then it cannot happen given long periods of time either. Hopefully you can see how silly that is.

[realhomosapiens]

@DNAunion

Where do we come from? I mean ultimatelly...if we go enough back in time, any idea?

[DNAunion]

@realhomosapiens

Going back some 360+ million years and including a myriad intermediate forms, we human come from certain long-extinct fish.

By the way; if you kiss a zygote will it magically and instantly turn into an adult human? No. Well then, do you claim that a zygote turning into an adult human is a fairy tale?

[realhomosapiens]

@DNAunion

Hmmm, interesting, What proof or evidence do have to offer that humans come from a long extinct fish? I mean, humans and any fish are totally different creatures...that is obvious...in order to make such a claim you´ve got to have empirical evidence, I´d love to know how can you support such a super-mega-extraordinary claim...remember, empirical evidence, assumptions are not acceptable...OK?

[realhomosapiens]

@DNAunion

Hmmm, I´m afraid you´ve gone insane...do you really think that all those things you just mentioned is evidence that your great-great-great-grandpa was a fish?

Did you know that there was a man outside the White House almost exactly to G. W. Bush? according to your similarity criteria they were twins, weren´t they? nooope, they were not even relatives, succulent plant genera, Euphorbia and Astrophytum are exaclty the same and they are NOT related...I guess they have deceived you

[DNAunion]

@realhomosapiens

"succulent plant genera, Euphorbia and Astrophytum are exaclty the same and they are NOT related"

All life on earth is related through common ancestry, including any two plant genera. It's only a matter of how related they are.

Humans and chimps are very closely related; humans and gorillas slightly less so; humans and orangutans less than that; and so on. But humans are related to mice (about 85.3% similiarity in genes), and fish ... and even to both of the plant genera

[realhomosapiens]

@DNAunion

So basically you´re one of those who trully believe that humans and bananas are related? hmmm, don´t tell that that´s kind of stuff it´s taught at the University near you? I´ve always taken for granted that Universities used to teach science, now I realize that I was too far away from the truth...

If humans and chimps are very close related, Who is that guy you´re talking about? any clue?

The origin of the parathyroid gland”, Masataka Okabe and Anthony Graham, PNAS, December 24 2004, Vol. 101, No. 51, p177716-177719.

Source of the following ...

[DNAunion]

@realhomosapiens

One of the anatomical homologies at this stage is the presence of pharyngeal arches and related structures, which are sometimes loosely called “gill slits”. Several lines of evidence indicate that pharyngeal arches in vertebrate embryos – which includes fishes and humans – are truly homologous structures. One of the latest evidences concerns the parathyroid gland in humans (and other tetrapods) and the corresponding internal gill buds in fish.

One of the latest evidences concerns the parathyroid gland in humans (and other tetrapods) and the corresponding internal gill buds in fish.

[DNAunion]

@realhomosapiens

Life started in the seas. Long before the first terrestrial tetrapod existed, fish needed to maintain homeostasis and one of the requirements was to maintain steady levels of calcium ions, Ca2+. As with other homeostatic regulation, one of the components needed is a sensor to monitor the system. The authors investigated and found that fish have calcium-sensing receptors in their internal gill buds, which themselves are derived from the embryonic pharyngeal arches.

[DNAunion]

@realhomosapiens

During the long transition from a wholly aquatic life of fish to the fully terrestrial existence of most reptiles and mammals, organisms gradually lost their gills. Yet throughout the transition, they still needed to maintain homeostatic control over calcium-ion levels. Because of the known function of the parathyroid gland – maintenance of Ca2+ levels in tetrapods – it, along with PTH (parathyroid hormone), evolved during this time to meet the need.

[DNAunion]

@realhomosapiens

It was long known that the tetrapod parathyroid gland has calcium-sensing receptors, which are coded for by a gene called CasR. The authors’ detection of the expression of the CasR gene in fish gill buds established a strong functional and structural link between the gill buds of fish and the tetrapod parathyroid gland.

[DNAunion]

@realhomosapiens

Further, like fish gills, the tetrapod parathyroid glands are derived from the pharyngeal arches. 

[DNAunion]

@realhomosapiens

In addition, a gene called Gcm-2 (which encodes a transcription factor) was known to be expressed only in the pharyngeal arches and then in the parathyroid of mice: the researchers found that Gcm-2 was also present in both the zebrafish and the dogfish, and further, that its expression in those animals was restricted to just the pharyngeal arches and the internal gill buds.

[DNAunion]

@realhomosapiens

In addition, they also discovered that the Gcm-2 gene is linked to the gene ELOVL2 in zebrafish, chickens, and humans. Thus there are strong similarities in function (maintenance of Ca2+ levels), genetics (Gcm-2 gene, which is also consistently linked to the ELOVL2 gene), structure (calcium-sensing receptors), and embryonic origin (pharyngeal arches as the progenitor) between the internal gill buds of fish and the parathyroid gland of humans and other tetrapods.

[DNAunion]

@realhomosapiens

Recent experiments had shown that fish, even though they do not have parathyroid glands, do possess two genes for parathyroid hormone (PTH). The researchers examined the fish genes and found their encoded proteins contain key amino acids needed for function, which served to confirm other recent work by another group that suggested fish possess fully active PTH. They found these PTH genes were expressed, and detected parathyroid hormone in the gills.

[realhomosapiens]

@DNAunion

Well, chickens tears and humans tears are almost exactly the same and they should not, Why?

All the observational data you just listed is not evidence for a humans fish ancestry, you have to add to all of that your evolutionary idea, in short you´ve got to hallucinate, but let´s assume your argumentation is correct, let´s move a little further, Which of those weird cambrian marine creatures do we evolve from and what is the evidence for it? this is going to turn very interesting

[DNAunion]

@realhomosapiens

In addition to (1) the "almost complete" set of anatomical structures, found in humans, that already present in bony fish, and (2) the anatomical, molecular, and functional homology between the fish gill buds and the human parathyroid, there are also ...

(3) The fact that human embryos start off with a very fish-like arrangement of aortae and aortic arches, which then must undergo much remodeling to end up in a human-appropriate arrangement.

[realhomosapiens]

@DNAunion

I did prove you that similarities means nothing when it comes to any evolutionary ancestry, Why do you keep arguing with it? BTW, Haeckel embryos were proven a hoax, an outright lie more than a century ago, don´t tell they are still in the text books? Kent Miller was abotu to take them away from his text books more than a couple of years ago...Why the educational system still insist in teaching wrong and outdated conclusions? seems to me you didn´t see Euphorbia and Astrophytum

[DNAunion]

@realhomosapiens

"I did prove you that similarities means nothing when it comes to any evolutionary ancestry,"

Um, no, dumbfuck, you did not.

You just parrotted some Kent Hovind bullshit.

[DNAunion]

@realhomosapiens

"BTW, Haeckel embryos were proven a hoax,"

Embryonic similarities are an observable fact; verifiable by photos.

You only show how completely ignorant of evolution you are by jumping way back to the late 1800s when I mention embryological evidence for evolution. Time for you to catch up, dumbfuck.

[DNAunion]

@realhomosapiens

Still waiting for you to support your assertion that chicken tears are almost exactly the same as human tears.

[realhomosapiens]

@DNAunion

hmmm, and you have forgotten that some humans smell like a fish, that´s another strong evidence that humans descend from a fish, isn´t it?....your similarity argument is silly, but let´s assume using the similarity arguments is valid...tell me Why humans and chimps are more close related at DNA level than chimps and bonobos when it should be all the way around? I mean humans and chimps must be less similar and chimps and bonobos should be more close related, explain that to me

[DNAunion]

@realhomosapiens

"similarity argument is silly,"

Your counters to it are fucktarded.

[DNAunion]

@realhomosapiens

Still waiting for you to support your claim that the tears of a chicken and those of a human are almost identical.

What are you waiting for, fucktard???

[realhomosapiens]

@DNAunion

Well if you didn´t know about the chickens and humans tears similarity then I guess you need a little bit of more education on biology, looks like to me you´re an amateur...and there is a lot of more you don´t even know nothing about it, ...complete you education, lest you make a fool of yourself, (you have done it) BTW cockroach and humans shares also a very similar protein to function, Did you know that? nooope, that´s to much knowledge for you, isn´t it? ....jejejejejejeje

[DNAunion]

@realhomosapiens

Ah, so the fucktard can't support his silly claim that chicken tears are almost identical to human tears.

Fucktard: 0

DNAunion: 5

[realhomosapiens]

@DNAunion

So basically when you have no arguments and not willing to conduct any objetive research name calling is your argument?...no my dear DNAunion, you´re millions years away from the truth and I do really encourage you to conduct a serios and objetive research on the data, I understand that such a research can lead you exactly where you don´t want to go, but if it´s so, so be it. and there are more facts that you´re willingly ignoring, this is not an educational debate, sorry for you

[DNAunion]

@realhomosapiens

So basically, because you are willingly stupid and religiously brainwashed, you make up retarded shit and show your ignorance, and turn you back on evidence.

Yes, it is really sad what a poison religion is to the human mind. You are an excellent example.

[DNAunion]

@realhomosapiens

So, asswipe, why can't you support your assertion that chicken tears and human tears are almost identical?????

[DNAunion]

@realhomosapiens

So, shit for brains, why can't you support your assertion that humans and chimps are more closely related by DNA than are chimps and bonobos???

[DNAunion]

@realhomosapiens

(1) human anatomical preqrequisites present in fish

(2) the relationship between fish gill buds and human parathyroid

(3) the fishilke arrangment of aortae and aortic arches in human embryos

(4) the same executive genes used in development of a human arm (a bat wing, mouse forelimb) and the pectoral fins of sharks and other fish.

(5) transitional fossils - Tiktaalik and many other just for fish-to-amphibian transition, plus others for 'reptile' to mammal

[gregrutz]

@realhomosapiens ''chimps and bonobos should be more close related'' Why dummy.

The FACT is Humans are closely related to Chimps. That is because they share a common ancestor. Chimps are closer to humans than they are to Gorillas, that is a fact. That is the way they evolved.

[DNAunion]

@realhomosapiens

"seems to me you didn´t see Euphorbia and Astrophytum"

I already refuted you on them, because you claimed they weren't related, when they are.

[DNAunion]

@realhomosapiens

In addition to (1) the anatomicalhuman chacteristics already present in bony fish, (2) the multiple lines of evidence showing the relationship between the fish gill buds and the human parathyroid, and (3) the fishilke arrangment of aortae and aortic arches in human embryos, there's (4) the fact that the same executive genes are used in development of a human arm (a bat wing, mouse forelimb) and the pectoral fins of sharks and otehr fish.

[NestorSanchez3D]

@realhomosapiens feel free to publish your results, and turn the scientific world around with your undeniable case for a 6000 year old Earth and Intelligent Design.

Until then, your beliefs are not any different from any other myth regarding Creation from cultures all over the world from the bronze age: interesting and sometimes beautiful tales that have no connection with reality and are easily disproved using our current knowledge.

PURPOSE OF LIFE

What Does Islam Say About Life's Purpose?

______________________________­___

Have you ever asked yourself these questions?

"What is the purpose of L I F E?"

"My life?"

"Your Life?"

People everywhere are asking the questions; "What is the purpose of life?" and "Why are we here?" You might be amazed to learn, that Islam is providing clear and concise answers for these questions.

[RedAlphaDingo]

@osamyoosama

No. Islam is spewing the same garbage it always has. It is way off track with reality and evidence, as all religions are. Learn some real science. Learn the truth about evolution and stop bringing your ignorance to these forums. Just because your religious leaders tell you that something is true, it doesnt mean it is. Learn to question and ask for evidence.

[RedAlphaDingo]

@osamyoosama

It is sign of complete and utter arrogance of any person to say to anyone else "i have the answers". Anyone who does so is telling you crap. Despite the fact that we naturally crave certainty, there is no such thing. Keep your mind open to more possibilities and never accept anything as the final answer. That is process of learning and science.

[RedAlphaDingo]

@osamyoosama

Honestly, what do you think is really true? The knowledge of Evolution through scientific discovery by the worlds leading experts over the last 150years that is backed up by conclusive and precise DNA evidence, or a book written about 1500 years ago by iron age desert peasants whos current religious leaders keep telling you over and over how true it is but provide NO EVIDENCE! Wake up fool.

Another person with no education in the field, thinking he is somehow qualified to refute the work of experts.

How quaint.

[jingle3]

jjukil, I think you give timmy way too much credit in your response.  His comment goes to the question asked of professor Shubin about anti-evolutionists saying of the discovery of Tiktaalik that it has only pointed out 2 new gaps! You just can't force someone to believe something they choose not to, no matter how much factual evidence is presented.

If you have not read Dr. Shubin's book "Your Inner Fish," get yourself a copy - it is excellent.

[jingle3]

Another very good book on the subject is "Evolution: What the Fossils Say and Why It Matters" by Donald Prothero.

[jjukil]

Yeah, I've been meaning to read "Your Inner Fish." I'll get to it some day. And thanks for the other recommendation. I hadn't heard about that one.

[VoteNixon2008]

>>So if you want to see an evolution, or transitional form--just let him know, he'll draw them for you.

___ Shubin actually has about a dozen actual Tiktaalik specimens in drawers in his lab. How the fuck are you going to argue with concrete evidence like this?

[Timbul53525253]

Why are creationists incapable of shutting the **** up and LISTENING to the evidence? Evolution is backed by the evidence. Evolution has won, creation has lost. It's not a matter of opinion. SHUT. UP.

[lushie]

@Timbul53525253 If you have to resort to SHUT UP then your argument has already failed. Obviously it is a matter of opinion since a lot of scientific explanation is not good enough for a lot of people and for some it is.

[Timbul53525253]

@lushie It isn't that the scientific explanation "isn't good enough", it's that people either haven't seen/read/listened to it, or are incapable of understanding it, or have only been exposed to Creationist strawmen. That's the point I'm making - the debate is over, and has been for quite some time. If you don't accept the evidence for evolution - as if you don't accept that the earth is not flat or believe gold is soluble in hydrochloric acid - you are WRONG, not "in an argument".

[JCH0720]

@Timbul53525253 No, evolution has taken good science as twisted it to fit its agenda. Carbon dating is a prime example of this, because no one can know exactly how much carbon was in a given fossil when it died. They simply ASSUME the amount of carbon to start with, then calculate the half lives. Believe what you will, that is your right but I bet if you could talk to Darwin right now, he'd tell you that he hasn't been an atheist for about 130 yrs.
