My apologies, English is not my first language.
Also I apologize as well for addressing Cyber as "dude"
I will continue this thread tomorrow

Apology accepted. Thank you. Now go have fun out there. You're gonna have your hands full, though. *chuckle*

If he returns, I am all ready with the choc bombs, popcorn, Shiraz for us, Tequilla for you missus. So much fun to watch that much swagger fold and run...

I'm afraid you will have to take that up with Old Man. He is the one doing the catering. I just bring the drinks. Name your poison.

I'm easily pleased. Coffee. I run on caffeine. But I don’t think we'll get the chance, Tin One- the dude skedaddled.

Oh man! That sounds disgusting! And is that caviar topping? *sigh* Well, if we're going all fishy, I'll bring the beer:

Damn, I was eating when I read that. I do not even find squid ink or shark flavor to be "disgusting" by it self, but on icecream?

Frozen cream from a bovine mammary organ with sugar added AND squid ink? Yeah seperate I have tried both, but together? Pass.

You should try vanilla ice cream with mustard. Get it all mixed up evenly and eat it with pretzel sticks. Surprisingly tasty.

Well one thing I wasn't going to 'bring up' and it is a thing uniquely Australian...( I used to quite enjoy it) is a good layer of vegemite on toast topped with a thick lashing of crunchy peanut butter.
Of course one of the major food corporations had to spoil it and produce a peanut butter ice cream topped with vegemite *retching*, quite put me off me rooburger.

Ummm... Yeah. Vegemite good on buttered sourdough toast. Vegemite good on grilled cheeseburger. Vegemite on ice cream?.... Nope. Nope-nope-nope.

@Algebe Re: Wasabi ice cream

Ooooooo.... Sounds interesting. My curiosity is officially piqued. Although, when I try stuff like that my wife looks at me as if I am some strange creature from another planet. But, hey, that's part of the fun. *wiggling eyebrows*

1) Reference the Pepper Moth.

2) Reference the Pepper Moth.

3) There is no missing link. The path from Lucy to Heidelberg Man to Nebraska Man to Piltdown Man to Peking Man to Neanderthal Man to New Guinea Man to Cromagnon Man to Modern Man has destroyed any "missing link" question.

4) Once again, reference the Pepper Moth

So far you have done a poor job at disproving evolution. I desire for you to discuss the Pepper Moth.

The pepper moth is not an example of something evolving, it's an example of natural selection. Two coexisting phenotypes, having their majority/minority roles switched on account of environmental factors.

John 61X Breezy,

Changes in gene frequencies is one way to define evolution! Natural selection is the main engine of evolution. What do you think it's doing when it shifts a population of moths from dark to light or from light to dark? It's a small step of evolution.

If you knew nothing about the world in which we live: it would seem a reliable source of information would be to take what Breezy says on a subject and assume the opposite is true.

Frequency seems irrelevant to evolution. Natural Selection is destructive rather than constructive; it eliminates variation rather than produce it.

In the pepper month example, the only change occurring is the way such variation gets eliminated.

John 61X Breezy,

Natural selection doesn't produce anything! It's a sieve. Natural selection favors the survival of organisms with helpful genes even as it tends to eliminate organisms with harmful genes. With competition renewed in each generation, and new combinations of genes to work with in organisms that undergo sexual reproduction, there is a tenancy for organisms to adapt more and more to a given environment. In that sense natural selection is constructive.

Since you are obviously not well informed on this subject, your opinion regarding genetic frequency changes and evolution is worthless and requires no further reply.

Pepper moths with protective coloring get a boost in their survival rate; those with harmful coloring lose ground. It's not just about elimination! Evolution doesn't come to a halt with the color change. It's just that the color change is the one change that can occur rapidly because of environmental pressure and genes already in place. Each generation continues to produce offspring with considerable variation, even though it may not be apparent to casual observation. Evolution continues to act on that variation. There is no reason to think that evolution has come to a stop just because the quickie part is over with!

Now that's an excellent post. You get extra marks for bothering as well, at this stage I'm reduced to a melancholy shake of the head in silent pity at such delusion, and a ruined education. His professors if they are aware of his delusion should be pilloried for not helping him.

Helpful genes vs harmful

Helpful genes vs harmful genes can only be defined as such in relation to the mandates of selection. Therefore, an organism is said to have adapted once it has escaped the immediate grasp of natural selection.

Your last paragraph seems to jump from a change in frequency to a change of color, so which is it? Did the color change, or the frequency?

Dave Matson

John 61X Breezy,

True, "helpful" and "harmful" genes are not absolute categories; they are only helpful or harmful with respect to the current environment. Genes for dark pigment might be helpful in a dark environment and harmful in a light environment.

Since when do organisms escape the sieve of natural selection? The fact that the pepper moth reaches a population mainly consisting of the protective coloring does not shut down all the other pathways of evolution! For example, the moths might be evolving a better way to digest their food or to handle hotter temperatures.

Since the dark color of pepper moths are due to one or more genes, a change in a population's color is obviously a change in gene frequency.

Right, but a change in

Right, but a change in frequency does not imply a change in color, which is why I wanted you to specify.

Both phenotypes were present before and after the environmental change. We didn't observe white moths change to black moths and back again. What we observed was a change in how many there were of each.

@JB

I made a mistake and technically you are correct. But my error is that in my haste I displayed perhaps the most elegant example of natural selection in the world.

Piltdown Man was a hoax, wasn't it? Otherwise I agree with your comment.
