LISA,
I was not aware that mutation which "developed the genetic information" was required for it to be considered "evolution". Even mutation which degrades the ribosome of a bacteria in order to acheive antibiotic resistance is evolution, because evolution deals with change of any kind. It almost seems as if you would define evolution as "improvement" which is fundamentally incorrect. Much like your example about bacteria, I would like to present an example with HIV. Mutations which endow HIV with resitance to antiviral drugs also slow the rate of reproduction of the virus. However, fitting in with the principle of natural selection, the HIV with the antiviral mutation survive while the faster reproducing viruses without the mutation do not. Indeed, it almost seems ridiculous that you would need to mention something like this. It is completely illogical to expect that mutation could somehow "produce new genes." Such a claim has never been made. However, as we have both shown, mutation can certainly alter existing genes, and thats when change occurs.

(Unrelated to that) I also have heard that as long as two animals are in the same genus, they can interbreed, but they form another species when they do so. That's the whole mule thing. As someone else stated, we can all change an itty bitty bit by evolution at a time to gradually form a new species, or we can take a huge leap and form a new species very quickly. Large mutations usually increase the rate at which the second option happens.

Mules are not anothe species... they are a Hybrid. Hybrids are infertile and thus can not reproduce themselves. Same goes for Ligers, Tygrons, Zedonks and so on.
on a side note an intresting link on actual hybrid animals (the whale/dolphin is wierd ) http://www.greenapple.com/~jorp/amzanim/crossesa.htm I don't have time or space to refute Mr. Spetners points... but some others have find them here: http://www.talkreason.org/articles/spetner_v2.cfm http://www.talkorigins.org/faqs/fitness/spetner.html http://www.fred.net/tds/anti/sharparguments.html http://www.fred.net/tds/anti/ http://www.nmsr.org/nylon.htm wa:do

oh I also forgot most of the 'statistics' that get thrown around are bunk.
![]() They are most often misapplications of "Borel's law" not an actual scientific 'law' mind you but an idea put forward by Emil Boral. Crationist got hold of the idea and ran with it... some helpful information: http://www.talkorigins.org/faqs/abioprob/abioprob.html http://www.talkorigins.org/faqs/abioprob/borelfaq.html any such statistics are to be taken with incredable amounts of salt ![]() wa:do

There are successful hybrids from interbreeding similar species, though... i.e wolves and domestic dogs; Bison and domestic cattle; It's done quite often with plant species as well.... Does this prove the theory of evolution? I don't think so, it just proves that closely related species can interbreed. Does mutation prove the whole theory of evolution? As a scientist, I still think there are too many gaps in the theory for there not to have been a higher power that not only got the whole thing started, but created the diversity as well. |

Ok, I don't know how to get multiple quote in my response so I'll just wing it.
Ceridwen018, I'll accept the abiogenis argument. My bad. Onward. Ok come up with a reasonably lower number of amino acis that are evident in sustainable life and run the number and I bet there are still astronomical odds against it. Don't leave out either the left handed/right handed amino acid case against abiogenisis. Or the argument where the forming of amino acids in an aqueous solution without a controling factor is impossible. Onward. "The probability calculations deal with sequential trials, as opposed to simultaneous ones. If indeed the earth formed as a result of a primordial soup..." The spark in the primordal soup concept has been shown not to be a workable solution in that what was left out of those experiment is that the number one result of that experiment was tar. The number two byproduct of the experiment was carbolic acid-not very condusive to life. Your statistical analysis of 1-4 is relevent in such a small number but not when using a ten to the 40,000 probabilty. Finally for you, this is only for one aspect of the building blocks nescasary for life. Without looking it up the need to bring together all the parts for life to begin is something in the order of a billionth power. Start counting. On to Pah. Prove evolution of unique species exists. Until then my staement stands. Next, No, "The minute you concede evolution within a species, you concede it on evolution between species." Prove evolution of a new species and all consider this. Also mules aren't fertile. Next. Last edited by sandy whitelinger; 03-10-2005 at 01:18 PM. Reason: misspellings |

How silly pah, there is no evidence of evolution of unque species. That is all the proof needed.

![]() "Billionth powers" (if indeed that is the correct number, which as I stated before, is impossible to determine) might seem like a big number to you, but when compared to a scale of duodecillion, for example, it is relegated to complete insubstantiality. Think of this: for someone who considers 1 x 10 to the -39th power a large number, the simple number 1 seems astronomical. Quote:
