Evolution is a Fact #1 - Protein Functional Redundancy

by cofty in

i intend for this to be one of a series of bite-sized ops on the evidence for evolution.. introduction to dna genes are sequences of dna made up of words (codons) each of which are three letters (bases) long.

there are only four letters in the genetic alphabet (acg&t) each word or codon is the recipe for one amino acid.

there are 20 different amino acids in living organisms.

I just read the Talk Origins article. Yokey's study utterly refutes the creationist case.

Hooby - I asked you to give me a reference for Yokey. I can't respond to your comments until you do.

I need to see exactly what Yokey said in context. Do you have a copy of the source you are talking about? Your obfuscation is tedious.

All of this is a distraction from the main point of the thread. Only evolution can account for the phylogeny of ubiquitous proteins such as cytochrome c.

You still have all your work to do to explain this from a creationist perspective...

The calculations by Yockey were not just for optimum sequences but for all possible functional sequences.

No it wasn't. You can't even understand the creationist arguments AGAINST the science. How on earth are you going to understand the hard stuff?

Please provide a specific reference and quotation with context.

You have ignored every word of my detailed answer. Are you just trolling or are you trying to genuinely understand the science?

Is there a pre-existing evolutionary predicting this?

That isn't even a sentence.

Yeast, insect, a fish, a bird, and a mammal all have approximately the same number of Cytochrome C differences relative to a bacteria.

I have challenged you FIVE times to work out why this is exactly what evolution predicts.

1st clue - Think about the relative timescales involved.
2nd clue - Cladograms

Come on you can do it.

WATCHTOWER Is Trying To Put Cameras In All of Their Kingdom Halls

by minimus in

jw
friends

one of my best friends is in the security business.

he told me the other day of how the watch tower has been in contact with his good friend and business associate.

evidently they are inquiring about putting cameras into every kh so that they can do 24 hour monitoring.

Crazyguy don't you think that's the sort of reckless comment that undermines valid criticism of the cult?

The odds of obtaining even one of these by chance is 2.0 x 10 -44 - Hooby

This is a distraction from the topic but let's get it out the way.

There are perhaps 20,000 different proteins in human cells. The average number of amino acids in these proteins is around 400 or so. That makes Cytochrome C a relatively small molecule at just 104 amino acids. Not one of evolution's biggest achievements.

Your challenge seems to be that evolution could never come up with any protein because 'chance'.

The answer to your question is to be found in chapter one of every basic textbook on evolution. It was the great discovery of Charles Darwin. EVOLUTION is NOT ABOUT CHANCE.

Life doesn't have to wait for its lottery numbers to come up - natural selection is a chance accumulator.

The crucial thing about a protein is its physical shape. Amino acids join together in random ways like oddly shaped magnets combining to make larger shapes with all sorts of bumps and crevices. Something that is approximately the correct shape will give its host an advantage.

The number of sequences that will produce something 'good enough' is orders of magnitude greater than the - astonishingly massive - number of sequences that result in the optimum version.

It arrives at its final form as a result of natural selection that favours any small improvement. After that, any future changes will be selected for if and only if they don't negatively affect the efficiency of its function.

Artificial Intelligence and engineering are using versions of natural selection to optimise design.

Yes of course they do. Even though I wrote this thread to describe the pattern of ubiquitous proteins in eukaryotes your point about prokaryotes adds to the evidence.

I have asked you FOUR times to have a go at answering your own question.

Why is the difference between prokaryote and eukaryote cytochrome c sequences exactly as evolution would predict?

I will give you a clue. Think about the time-scales.

We are on page 28 and you still haven't explained the facts in the OP from the perspective of creationism.

It's almost as if you don't understand your own question - or the topic, or anything at all about evolution.

Thought Provoking Question to a JW?

by Solzhenitsyn in

did jesus ever utter the name jehovah?.

and if he didn't what are the implications?

nwt answers don't count but feel free to use the kingdom interlinear.

cofty

I think it's an excellent question.

The gospels record Jesus challenging religious traditions and the confrontations that ensued. Not one word about the divine name.

Three possibilities...

A - He did use the divine name and nobody objected.
B - He did use the divine name resulting in massive outrage and the gospel writers never thought to mention it.
C - He didn't use the divine name.

Come on Hooby don't run away now.

First explain how creationism explains the table below, and then tell us why cytochrome C in prokaryotes are significantly different from all eukaryotes just as evolution predicts.

I have asked you three times if you understand why the diagram you posted regarding prokaryotes is exactly what evolution predicts?

You are the one avoiding the topic not me.
