Nothing evolved

Standen says it’s exciting to think that we can use experiments on living animals to make inferences about what might have happened to physically similar animals during large scale evolutionary transmissions.

They experimented on living animals. They picked ones similar to the type they believe 'might have' been 'physically similar'.

They took a fish that would most likely survive and move out of water. They explained that there are living animals (fish) today that can breath air. They took one and experimented on it. Nothing evolved. Let alone in 'one generation'. LOL

Intelligent Design anyone?

You obviously didn't read about the morphological changes (change = evolve). Continue believing in invisible barriers.

This kind of title and thread look like any of the sale ad. and can be trashed directly without even open it.

So why don't you without c&p?

Interesting article. Thanks for posting!

So, you actually think evolution, biological evolution, is equivalent to change? May I ask you if it is your religion that makes you feel education is anathema?

I don't see this much different than someone learning to walk on their hands or someone without arms use their feet in place of hands.

Wow! under very controlled condition, an environment consisting of mesh flooring covered in pebbles and 3 millimeters of water — a precaution that, combined with water misters, prevented the fish from drying out. Very natural conditions! How long do you think these trained walking fish would last in the wild?
Scientist made fish walk, well so what? You can make dogs, horses, and other such animals to walk on two legs.

One of the scientist Emily Standen claims that many of the anatomical changes mirror the fossil record, then you don't need experiments, show us that steps within the fossil record! She goes on to say: "it’s exciting to think that we can use experiments on living animals to make inferences about what might have happened to physically similar animals during large scale evolutionary transitions." "It seems quite clear that environmentally induced changes may have facilitated their transition to land"
Inferences, what might have happened, may have facilitated?

Also don't forget about phenotypic plasticity.

Sigh, the information came from a paper in Nature. http://www.nature.com/nature/journal/vaop/ncurrent/full/nature13708.html

Are you going to trash articles from that publication too?

You're welcome.

Yes, biological evolution is equivalent to change in a more competent way (less competent is devolving). If you'd like to look up evolution in an elementary science text book, you will find this to be the case. My intuition is that I am more educated than you, but I'm willing to give you a chance.

I don't see this much different than someone learning to walk on their hands or someone without arms use their feet in place of hands.

That is true except that if walking on hands allowed individuals to live in a new area, reproduction over time would result in organisms with more capable arms and hands.

To answer your question, fish would live quite long in the wild if they were the first sea creatures to venture onto land. There wouldn't be anything to devour them.

There are millions upon millions of transitional fossils. You refuse to accept any of them, all while asking for more of them. Your objections are based on a religion that says a metallic dome is the material of the sky (see Raqia), and are not based on science or logic whatsoever.

Also don't forget about phenotypic plasticity.

Apparently you believe in barriers for animal classifications in that they can't change past a certain point. Can you point me to the genes that are unchangeable?

You meant like dGRN? Either a change in dGRN will have a back-up or the embryo development will completely stop. This have been shown to be true in the lab but there nothing to stop someone believing somehow dGRN were a lot more flexible in the past than they are today.

Citation?

Did they show that a mutation at every position in the gene results in a non-functional or deleterious allele?

Added in edit: It appears that GRN stands for gene regulation networks. Assuming this is the case, I thought it might be interesting to look at one of the human homeobox genes. The following page lists the known variants of the human Hox4I:

Ensembl genome browser 76: Homo sapiens - Variation image - Gene: HOXD13 (ENSG00000128714)

There are quite a few missense mutations on top of synonymous mutations. So much for there being no mutations in these genes.

We have plenty of pages here at CF where creationists demand that laws were different in the past. It is quite strange to hear creationists demanding abiogenesis be observed in the lab, all the while rejecting decay rates and geologic mechanisms that are directly observed in the lab and in the field. Some consistency would be nice.

 

[BL2KTN]

Loudmouth has responded similarly to what I was going to. I find your answer entirely inaccurate and inadequate.

nice mutation.

"This gene belongs to the homeobox family of genes. The homeobox genes encode a highly conserved family of transcription factors that play an important role in morphogenesis in all multicellular organisms. Mammals possess four similar homeobox gene clusters, HOXA, HOXB, HOXC and HOXD, located on different chromosomes, consisting of 9 to 11 genes arranged in tandem. This gene is one of several homeobox HOXD genes located in a cluster on chromosome 2. Deletions that remove the entire HOXD gene cluster or the 5' end of this cluster have been associated with severe limb and genital abnormalities. Mutations in this particular gene cause synpolydactyly. [provided by RefSeq, Jul 2008]

Often when you mutate or knock out genes or DNA that causes the cell to fall back on "plan B" it has a high cost to the creature's overall fitness.

 

[CabVet]

nice mutation.

But of course, he didn't mean this:

Deletions that remove the entire HOXD gene cluster or the 5' end of this cluster have been associated with

Which immediately precedes the sentence that you highlight. Honesty is too much to ask, I guess.

 

[CabVet]

Often when you mutate or knock out genes or DNA that causes the cell to fall back on "plan B" it has a high cost to the creature's overall fitness.

And much more often mutations are neutral, causing no change. But of course, you are not interested in facts.

 

[Smidlee]

And much more often mutations are neutral, causing no change. But of course, you are not interested in facts.

When it comes knocking genes there is often a very high cost to fitness. This is why you can't determine the function of a gene or lengths of DNA by knocking them out. What we may assume to be neutral may not be neutral over long term.
