The Theory of Evolution is split up into two sub-categories:

Microevolution

"Microevolution is evolution on a small scale — within a single population." [1]

Macroevolution/ Speciation

"The formation of new and distinct species in the course of evolution." [2]

I will be defending both microevolution, and macroevolution/ speciation.

By evolution is true", I simply mean that the evidence for evolution is so overwhelming, that it would be outrageous to deny it once confronted with the evidence.

First round is for acceptance.

If you believe evolution is correct there is many flaws in your belief. To start how did the thing we "evolved" from get here?

My Opponent's Claims

"If you believe evolution is correct there is many flaws in your belief."

The first round was just for acceptance, but I will address your comments anyway. Unfortunately, with regards to the above, there was no reason given why my belief is flawed.


"To start how did the thing we "evolved" from get here?"

Scientists believe that the first simple life formed by a process called Abiogenesis [1]. However, I am not here to defend Abiogenesis, I am here to defend Evolution. Since the two theories are not the same, this line of questioning from my opponent can be disregarded.

Evidence for Evolution

There is so much overwhelming evidence for Evolution, that it is fair to say it is scientifically proven. However, I only feel the need to mention two areas of evidence:

1. Chromosome # 2


2. Directly Observed Evolution/ Speciation


Chromosome # 2


Humans have 23 pairs of chromosomes, while all the other apes in our family have 24 pairs of chromosomes [2]. The chromosomes could not have gotten lost in our lineage, because that would be fatal. Thus, the only rational explanation if Evolution is true, is that chromosomes fused together, to account for the lesser chromosome count. If scientists did not find the fused chromosomes, then evolution is in trouble. Scientists found a chromosome which is actually two chromosomes fused together, it's call chromosome # 2 [3], and most humans have two of these. This shows strong evidence for Evolution, because the two fused chromosomes are actually primitive ape chromosomes. This find would literally make no sense if evolution was not true. Due to the amazing discoveries regarding Chromosome # 2 in humans, it is safe to say that human evolution has been demonstrated beyond a reasonable doubt.


"We conclude that the locus cloned in cosmids c8.1 and c29B is the relic of an ancient telomere-telomere fusion and marks the point at which two ancestral ape chromosomes fused to give rise to human chromosome 2." - J. W. IJdo [4]


Directly Observed Evolution/ Speciation

Evolution has actually been observed in laboratories, and is observed in laboratories. For example, why is it that vaccines always change? This is because, the viruses keep adapting to the vaccines [5], and they change so much that vaccines have a hard time keeping up with the pace. What about new species actually arising from evolution (which is called speciation)? Well, for example, some plant species can actually arise through evolution, even in as little as one generation. An example of an observation of speciation involving plants, was a study done by Hugo de Vries. He was studying the genetics of Oenothera Lamarckiana, and discovered that a new variant evolved that could not breed with the Oenothera Lamarckiana, and had a different amount of chromosomes. This means, a brand new species evolved, that was observed in a laboratory over long periods of time (he named the new species O. gigas.)[6]. Speciation has actually been observed first hand in the insect world as well. One example is the findings of Dobzhansky and Pavlovsky that were made observing a culture of Drosophila paulistorum [7].


Conclusion

Not only do we find the truth of Evolution in our chromosomes, Evolution is actually observed and recreated in laboratories all of the time, and has been proven beyond a reasonable doubt. Therefore, I have met my burden of proof, and the resolution has been affirmed.

I checked back to vote on this and it turns out the voting period is up.

@ RationalThinker, I suggest using the forfeited debates thread so you can at least get votes for conduct. No reason to let a forfeited debate be tied.

This should be interesting assuming bigbee99 shows up for the rounds.

The last "Conclusion" was supposed to be "Sources", my apologies for the mistake.
