Evolution is defined as change of allele frequencies over successive generations and the saubsequent diversification of life due to various factors.

Endogenous retroviruses, avida simulation and phylogentics make up some of the evidence which supports evolutionary theory.

Rules: start off with 3 arguments max. Absolutely no gish galloping.

If you're going to take part in debate, do not forfeit rounds. If you are unable to make an argument, post your argument as "forfeiting round," and I will do the same

All that said and done, I'm off to make myself a cuppa.

Con

As the con speaker in this debate round I will provide some points of clarification as well as three points of refutation.

Clarification:
- My opponent has essentially defined evolution as changes of alleles over successive generations. I would imagine my opponent is referring to the general concept of macroscopic evolution (large scale changes) as opposed to microscopic evolution (microscopic changes).
- Microscopic evolution is a perfectly valid and proven theory. With that said my argumentation will center around the claim that macroscopic evolution is an unproven and invalid theory.

Argumentation/Refutation:
1. Lack of Fossil Record - One of the core philosophies of evolution is lots of time. One result of enormous amounts of time is an enormous amount of fossils. With the idea of macro evolution, an organism undergoes progressive changes over numerous generations. What this implies, is that there would be many generations that live and die during this progressive change. However, decades of fossil research has discovered practically no evidence of macro evolution.

2. Adaption vs. Evolution - Often adaption is confused with evolution. For example, humans are white, black, and every color in between. This isn't a result of genetic evolution, it is a result of adaption to the environment. This same principle is applicable most instances of claimed evolution.

3. Evolution is stupid - because it is. I dont feel like typing out another reason. lmao

I figure I might as well structure the rest of my response. It's something I'll have to get used to.

Intro

With regards to Con's clarification, there are a few problems. Micro and macro evolution are the exact same thing. If con wishes to make a distinction between the two, that is fine, but it comes with the caveat that micro and macro are the exact same; the only difference being time.

I would also like to point out that "proof" does not belong in a discussion pertaining to science. Proof belongs in mathematics s the answers arrived at in mathematics are axiomatic in nature. This is not the case with science. In science, we deal with evidence, not proof. A small technicality, but an important one to make.

Con's Arguments

i) The fossil record is of course imperfect. Very few animals become fossilised as the process for fossilisation requires a very specific set of circumstances. That's the reason for the lack of fossils.

Furthermore, whilst the fossil record is imperfect, we see many indications of evoltuion occurring via the study of these fossils. Gogonasus is one such example. For instance, the pectoral fin of Gogonasus shows striking similarities with regards to the pectoral fin of Tiktaalik. However, this could be homoplasy between Gogonasus and early tetrapods [1].

So how about another example? How about Australopithecus Afarensis? Specifically, let's talk about Lucy (AL 288-1). This find forms one of the more important examples as Lucy's pelvis structure, vertebrae and femur strongly suggests bipedality [2].

ii) Con claims that adaption is different from evolution and that skin tones are because of adaption to the environment. Whilst I am myself not too sure of how different skin tones first originated, Con’s claim that adaption to environmental factors is not evolution is quite frankly, ridiculous. Natural selection is one of the mechanisms by which evolution occurs, so it therefore puzzles me how Con can claim that populations of organisms adapting to their environment is not evolution.

but are microbes real?

Evolution is proven fact. Its not a theory. No one can refute this... Antibiotic resistant microbes is 100% confirmation and certification and proven fact that evolution is taking place right here in the here and the now. Antibiotic resistant microbes are evolving every single second of every single day to become more resistant to antibiotics.
