Author | Topic: Give your one best shot - against evolution | |||||||||||||||||||

quote: There are physical and physiological differences between thedifferent races of humanity. Those differences are (in many instances) directly attributable tothe environments in which those races developed. Some similar environments with a geographical isolation havedeveloped different variants of humanity (Egypt & Australia spring to mind). Doesn't that favour evolution rather not? And I didn't think speciation was contested anyhow ...maybe I'm wrong there.

quote: True ... the point I was addressing was more the 'nor any sign of'part. Also trying to point out that similar yet geographically isolatedregions have developed different types of humans... tending to support evolution not refute it.

quote: It may be harder to believe, but that doesn't make it false,does it ? Someone else may point out:: 1) evolution doesn't depend on abiogenesis. Evolution is aboutthe diversity of life, and that life evolved from one or more common ancestors over a period of approx. 3.5 billion years (is that English or American billions ... does anyone know what the standard is these days ?) 2) Evolution is not pure chance. Evolution relys on the organismhaving traits which may or may not be beneficial depending on the environment it finds itself in. Those traits which are beneficial help the organism survive, and increase its chance of reproduction. Since the traits are heritable, the traits of those organisms that breed most will dominate the population. Speciation happens. Even most YEC's accept that (some even relyon it to account for the numbers of creatures required on the ark by Noah to be manageable). All evolution is postulating is that if, over a few thousands ofyears we can go from some proto-big-cat (for example) to lions, tigers, pumas, cougars, panthers, leopards, etc. then the accumulation of changes over millions of years could lead us from small shrew-like mammals to the vast variety of mammals we find today ... and over billions of years from single-celled creatures to multi-celled creatures. Is that so hard to believe ... that over the course of several millionyears, an accumulation of changes could lead to the diversity of life we see today ? There is a wealth of evidence that can be interpreted as supportingevolution ... and more is coming to light as we find out more about genetics etc.

quote: Why ?
quote: But those that COULD survive would, and pass on that survivalability to their (near) identicle offspring. quote: A reproductive system does not spring into being over-night. Aspects of it develop over time. First, perhaps, we end upwith close-knit colonies of single celled organisms, which then become so dependent on one another that they can only live AS a colony. Some cells develop specialised purposes ... I won't go on with the speculation, anyone can do that ... butthen your entire argument is one of incredulity ... I can imagine many ways that even the most complex appearing 'systems' could have come about gradually ... that's my opinion ... perhaps we could argue data instead ? quote: Not so. The steps that CAN lead down the path will, while theothers will die out. quote: So what is the barrier ? What is the reproductive rate of a single celled organism ? Split once every twenty minutes for 1 billion years and whatpopulation level do you have ? quote: Radically change the environment and the critter will most likely die,like the dinosaurs, but the same change may not be so radical for other critters. quote: Evolution isn't progress, it's just change. We only view it as progress so we can think of ourselves asspecial

OK, so what do YOU mean by information ?

The probability value of 1/10^65 is to make a
PARTICULAR 100 amino-acid chain isn't it ? How many 100 amino-acid chains are there ? How many tries can there have been in the billion yearsprior to the first cited modern-like cell ? Who says that the origin of life had to start with a cellas we know them today, 3.5 billion years later ? What about the virus example is it that suggests design ? Incredulity ? That's hardly a good argument is it ? The whole concept of using probabilities to verify an eventfor which we don't actually know the conditions or raw materials or time scales seems a little contrived to me.

quote: Oh dear ... doesn't that mean you now have to proove that thereis a programmer of the genetic code to make any claims that it is information at all ? I thought people were arguing that the information contectprooved it was created/designed, but now you are using a definition of information that requires knowledge of the programmer. [b] [QUOTE]
Here would be acceptable examples of new information: 1) A new program installed on your computer (such as WordPerfect), where it did not previously exist 2) A new gene (likely set of genes) that produce sonar, where sonar did not previously exist in the genome. [/b][/QUOTE] 1) does not refer to information ar all, it's just data. 2) has new data (the gene) introducing new information (the sonar). Change to the gene is not a change in information, but data. So the EXPRESSION of the gene is the INFORMATION. So shrimp leg supression consititutes new information. Whether a change is negative or positive it is new informationif it changes an expressed trait. No amount of dictionaries handed to you give you information,only data. If you read and interpret that dictionary you have gained information from it. Change the data in an interpretable way, and you have newinformation. In your dictionary example, instead of a typo change a crucial word within a definition (or introduce a typo that is still a valid word). The information conveyed is different, and since it wasn't there before, is new. In genetic terms if you were to accept that the expression ofthe gene is the information/interpreted data then any change that changes the expression is new information.

quote: Surely that is what is required for natural selection ? Genes which, in the current circumstances do not effect thefitness of an organism, but which might if there was a change in the current situation. ... already asked if by knocked out you mean in isolation (i.e.just one) what if you knock out three at the same time ? maybe they interact in an unexpected/unobserved way ... is that tested too ? quote: No its not. Unless you can show why information theory is relevent.
quote: OK. You are free to believe whatever you like, and you can run anyclaim you like by me. quote: Please do, it's much easier to debate evidence than opinion.

Isn't the use of information theory in the context
of the genetic component of organisms the exact kind of false analogy that you have just out-right rejected (without argument I might add). The purpose of analogy is clarification, by changing thesubject matter to something more mundane. As such, to argue against an analogy requires a comment on why it is not approriate, rather than just saying 'That's an analogy so I won't listen to it.' For me, for example, applying information theory to biologicalsystems is problematic. Just because we view the genome as a genetic code, doesn't mean it is actually a code in the technical sense of the word. The term 'genetic code' is itself an analogy, and not a technical description.
