Burden of proof is equal. Pro will argue for Evolution as a scientific theory, Con will contest and argue it is a fallacy.
For clarity, definitions : 1) Fallacy : a false idea, plausible however uses invalid inferences [1] 2) Evolution : Descent with modification. [2] 3) Theory : A scientific theory or law represents an hypothesis, or a group of related hypotheses, which has been confirmed through repeated experimental tests. [3] [1] http://www.merriam-webster.com...... [2] http://evolution.berkeley.edu...... [3] http://teacher.pas.rochester.edu...... First of all, calling evolution the scientific theory and saying that I am con to it is saying that I am against science. I am not against science, I am for truth and against error. First I would like to discuss how evolution defines the above definitions. 1) Fallacy : a false idea, plausible however uses invalid inferences We both already know my stance on this issue. I am against evolution because I do not believe that science proves the universe to be billions of years old but rather only a few thousand, namely 6000 as far as I can tell. 2) Evolution : Descent with modification. This is possibly the most divisive issue as far as I can tell. There are several different types of evolution: elemental, the evolution of elements; stellar, the evolution of the stars; planetary, the evolution of the plantes; macro-evolution, the evoluion of species from one to another; and micro-evolution, the modification inside a species. The only observed evolution is the last, changes within a species. This happens all the time, but all the others are believed to be true. We have never observed a star or planet form; we have never seen elements change above iron, event though there are many elements above it; and we have never seen any animal inside a species become an animal outside that species. 3) Theory : A scientific theory or law represents an hypothesis, or a group of related hypotheses, which has been confirmed through repeated experimental tests. "Which has been confirmed through repeated experimental tests." This has never been observed as far as evolution goes. Never has anyone experimented with any form of this except in modificaiton inside a kind. This is micro-evolution which I believe whole heartedly. |

"First of all, calling evolution the scientific theory and saying that I am con to it is saying that I am against science."
To be clear, con is against evolution being a scientific theory, not that there is no such thing as a scientific theory or science. "I am against evolution because I do not believe that science proves the universe to be billions of years old but rather only a few thousand, namely 6000 as far as I can tell." Note the theory of evolution as defined in the above does not imply the age of the universe, the current evolutionary synthesis, descent with modification even holds if the universe was created 6000 years ago with a number of unique kinds in fully developed complex forms. Note the well known bacterial experiments of Lenski, which while only taking place over 20 years, readily demonstrate and support the theory of evolution as defined in the above[1]. Of course if it was true that the earth was only 6000 years old it would contradict universal common descent (there is a unique anscestor to all life on earth), which is derived from the theory of evolution when applied to the current understanding of the age of the earth. Universal common descent (UCD) is well established in the literature, with the most recent modeling article by Theobald providing new evidence as well as an excellent review article on the history and evidence for UCD. [2] "There are several different types of evolution: elemental, the evolution of elements; stellar, the evolution of the stars; planetary, the evolution of the plantes; macro-evolution, the evoluion of species from one to another; and micro-evolution, the modification inside a species. The only observed evolution is the last, changes within a species. This happens all the time, but all the others are believed to be true. We have never observed a star or planet form; we have never seen elements change above iron, event though there are many elements above it; and we have never seen any animal inside a species become an animal outside that species." Note the above definition of evolution was very clearly biological, additional debates can be held concerning the other uses of the term popularized by Hovind a popular creationist apologist. Specific to this debate the claim "we have never seen any animal inside a species become an animal outside that species" is false. In fact it is so well known to be false and the evidence so strong against it that even Hovind has stopped using this as an argument. The most well documented list of speciation is given on talk.origins [3]. This collection and commentary on speciation events notes hundreds of peer reviewed articles which report speciation again and again for the last 100 years. Again, over a hundred years of papers all supporting the theory of evolution as defined in the above. "Never has anyone experimented with any form of this except in modificaiton inside a kind." In order to contest this, it would need to be defined as to the nature of a kind in a way of course which can be demonstrated and falsified as if one animal is the same kind as another. [1] Bacteria make major evolutionary shift in the lab [http://www.newscientist.com...] [2] Theobald, Douglas L. (13 May 2010). "A formal test of the theory of universal common ancestry.". Nature 465 (7295): 219–222 [3] http://www.talkorigins.org... "Note the well known bacterial experiments of Lenski, which while only taking place over 20 years, readily demonstrate and support the theory of evolution as defined in the above." Observed Instances of Speciation(this is the title these are under) Plants Despite the fact that the plants were in different genera, he got a sterile hybrid. (sterile, cannot have offspring. This is where we came from?) Artificially doubling the chromosome number using colchecine produced a hexaploid hybrid which closely resembled M. citrigracilis and was fertile. (if it is artificial, how did evolution naturally do it?) When grown in the lab, the tetraploid sporophytes appear to be less vigorous than the normal diploid sporophytes. (less vigorous sounds like a loss of traits, not a gain.) Animals The basis of this was changes in the courtship behaviors of both sexes.(so a change in courtship is a sign of progress? Why haven't we mastered it yet?) They concluded that sexual isolation was produced as a byproduct of selection.(Male and female separation is not a way to mate and evolve.) All of these show problems that came up. Now sure some stuff did go right, but it never resulted in a change of species. About the best thing that came about was a better mating life (which humans do just by being flirts). This is not anything to show evolution where a fruit fly changes into a whale or even into a bee. It was still just a fruit fly afterwards. "In order to contest this, it would need to be defined as to the nature of a kind in a way of course which can be demonstrated and falsified as if one animal is the same kind as another." This is something that any kid could tell. Kinds are able to produce offspring together. Dogs and wolves can produce offspring. Dogs and fish cannot. Is it really that hard to figure out? |

In summary, not in this round, nor in the previous did Con actually attempt to refute the resolution as stated, instead ignored the definitions and argued against contentions created simply for the purpose of denying them.
Note the definition of evolution has never been directly contended to be a fallacy, nor has any of the evidence for it been refuted. In closing, some remarks will be made about comments on the references provided. "These bacterium grew accustomed to citrus, not changing species. It is still the same bacterium, it can just stand something it couldn't before." Using lay terms in a scientific discussion is not going to be productive, what is the meaning of "accustomed" and what does it say exactly about the inherited traits of the population, this is the topic at hand. If the population passes on this being "accustomed" in successive generations (which it did) then by the above definition it is an example of evolution. "Creationists say the bacterium cannot turn into horses or fish. That is a huge difference." Indeed, and UCD deals with this assertion as noted in the above. This point stands uncontested. "I'm sorry, but I thought that science was supposed to be about observed facts, not inferrences. " An inference is the act of drawing a reasoned conclusion from observed facts. "Despite the fact that the plants were in different genera, he got a sterile hybrid. (sterile, cannot have offspring. This is where we came from?)" What is the point of quote mining when it can be made clear it is a quote mine, the full text : "This allowed for the production of seed. Plants grown from the seeds were interfertile with each other. They were not interfertile with either parental species. Unfortunately the new plant (genus Raphanobrassica) had the foliage of a radish and the root of a cabbage." "(if it is artificial, how did evolution naturally do it?)" Polyploidy, or the duplication of chromosomes is caused by many factors, in humans for example it can happen simply due to multiple sperm fertilizing the egg. They were simply trying to induce a rare event specifically to test a hypothesis. "... it never resulted in a change of species." Again, speciation was clearly observed and documented to fit the specific definitions noted, and the actual names of the new species were given in each instance. "This is not anything to show evolution where a fruit fly changes into a whale or even into a bee." Is it really being argued to demonstrate speciation, an experiment has to show a fruit fly population evolve into a whale population, that there is no taxonomic rank between those two other than species? "Kinds are able to produce offspring together. Dogs and wolves can produce offspring. Dogs and fish cannot." Are people the same kind as a chimp? "When Nick Patterson of MIT and his colleagues at the Broad Institute compared the genes of humans and chimps, they found that one of the chromosomes -- the female sex chromosome X -- was 1.2 million years younger than the others. It appeared the two species shared a common ancestor who gave them both their X chromosomes, and did so more recently than the ancestors who gave them all the other chromosomes." [1] The interesting there here is that there are two cladistic nodes, which points to at a point where humans and chimps first separated those populations diverged (human line and chimp line) but the population was able to produce a secondary node over a million years later, i.e., early human and chimps were interbreeding. Note of course not only does evolution cause divergence above the species level, this can be traced backwards and end up with a universal common ancestor, a prediction which has been tested and is peer reviewed as noted in the above.

I am not arguing the definitions; I believe the definitions are fine. What I am arguing is the fact that these terms are used incorrectly to describe the wrong things. I have already stated above how the actual terms cannot apply to the evolution belief. I do not even contend the "definition" of evolution; I just contend with the accuracy of this belief. And, yes, I did refute the evidence you brought to this debate. The bacterium evidence I refuted already; I'm not saying it is false, I'm just saying that the wrong conclusions were inferred from the facts. Your statement about evolution being "very clearly biological" shows only a small percent of the actual theory of evolution. Yes, the odds of biological evolution happening is nearly impossible, the odds of the stage being set for biological evolution to happen is an even smaller percent. "If the population passes on this being "accustomed" in successive generations (which it did) then by the above definition it is an example of evolution." The African Americans have darker skin than Caucasians or even Orientals, but that doesn't show any evolution or development of new species. This is one reason I hate the term "micro-evolution" so much: it is improperly connoted. It is simply variations, not evolution of a new kind. "An inference is the act of drawing a reasoned conclusion from observed facts." Sorry, I guess I improperly defined evolution's "inferences"; you say that it is a reasoned conclusion. "They were simply trying to induce a rare event specifically to test a hypothesis." The one problem I have is that these "rare event"s would have to happen in relatively close proximity of each other to carry on the genes. And if it was just to test a hypothesis, then it should not be shown as evidence for evolution. "Are people the same kind as a chimp?" No, they are not. But in pro's statement, he shows that the one DNA is 1.2 millions years older than that of the other. Since when have DNA chromosomes carried around dates!! It is amazing that anyone would argue this point. How can someone tell which is older. The questions from this are, "How did these species keep from intermingling when they were still fertile? How did they make sure that the correct traits are passed on? If we have chimps and we have humans, where did the intermediate species go? If we have been evolving for billions of years, where are the bones from these creatures?" These are questions that evolutionists have never been able to answer. And this is just for human evolution: how did it happen for fish, dogs, frogs, and birds? Where are all of those fossils? Also, the rest of the article that pro cited had some interesting features. There were countless "might have, probably, seems to have." This is not science. Science is made up of "did and does," not could, should, and would. My favorite is the statement "must have belonged". Well, of course it must have, to prove evolution correct. But the fact is that, it was never observed to have happened, and if the most they have is "If some of those hybrid females then bred with proto-chimp males, some of their male offspring would have received a working X from the chimp side of the family", I am sorry, but it will take a little more to convince me than IF. My final statement is just simply this, the only arguments made are: variations in a kind, and if, could,would. There has not been any solid proof, just proof that can be interpreted different if someone is trying to proof a theory they are biased to. I would like to say that I appreciate my opponent issuing me this debate. I wish him guidance and wisdom in any debate he has in the future and would like to clarify that there is no malice from me to him at all. |

What I actually hold to be true, and what I would debate are often not the same thing yes.
There are a few lines of evidence for UCD, one of them is combining the age of the universe and extrapolating population divergence over that time period, however there are other lines of evidence which do not and for example use things such as ERV to link animals above the species level.
Yes we can debate the age of the earth, I can draft this up later today.
Exactly right, you can`t (not from that evidence).
The theory of evolution only states what happens from one population to the next. Now the diversification of life and the origins of life are also asserted in Biology as various laws and theories and others still are in the hypothesis stage. But evolution theory itself is not so restricted that even if these were falsified evolution would still remain.
For example, evolution with a significant amount of other observations predicts ultimate common descent (we share a common ancestor with a banana), however and this is the critical part, these observations are not necessary - there is nothing says that they had to happen.
Life could have for example originated with two distinct lines, one for plants and one for animals, there is nothing in evolutionary theory which says they *had* to have a common ancestor.
We observe things such as ERV`s which when combined with evolutionary theory points to cladistic tree with one node (common ancestor), but again if we did not observe them, evolutionary theory on its own - would not compel it.
"how does arguing that the bacteria stayed bacteria oppose "descent with modification"."
Yes it was modified. But you can't say that we came from bacteria from this reference. All you can say is that we can adapt to our environment. I have never contested that.
"To this date I have not seen one debate where the actual theory of evolution is actually contested, it was never even contested here and I specially defined it to see if it would."
Well, I can't argue with the definition you gave. It is to general a statement. Do I look exactly like my parents? Obviously, no. That is a modification. I believe, for future debates on this topic, a more exact definition of what evolution theory should be given. If you would like to redebate this with a knew definition, that would be fine by me. We might acturally get somewhere instead of just getting to "you didn't argue the point I gave." Let's try; this again, shall we?
Care to debate that?
