Evidence for Evolution, Part I

I've gotten tired of explaining why Intelligent Design and Creationism are wrong, why they are not supported by the data, how their supporters misrepresent facts or lie, and why they are not science. So now I've decided to show evidence for evolution. In this simple experiment I analyze codon usage in the alpha and beta chains of hemoglobin. The theory of evolution makes a simple prediction: codons not subject to bias should be preserved in closely related species even though there is no selective pressure to do so. ID and creationism make no predictions about this data. God, the designer, could have kept the codons the same or could have switched them. ID and creationism are indifferent since we cannot know the reasoning of god, and that is why they are not testable.

The argument presented here is not circular. I define human, chimp, and rhesus monkey as closely related based on a wealth of other data (they were believed to be close relatives before we even understood what DNA was).

Finally, what I don't show in the video is that the codon usage for glutamic acid in these proteins in chicken (a very distant relative of primates) is not preserved. 3 of the 9 conserved glutamic acid residues use different codons compared with primates. This has a probability of roughly 25%. Telling us that given enough time random mutations will cause non-functional regions of DNA to diverge.

In the end, this data supports evolution because the theory made a prediction and the data confirms that prediction. Plain and simple.

DNA sequences from completed genomes are available online for everyone to play with. So go ahead. Look at it for yourself.

Evolution is a religious ideology. It is dated at before 2600 years ago.

I don't know why anybody follows this religion but it seems to be relative to the degree of genetic degradation shown in the human genome. ... A rather rapid degradation of intelligence. Particularly in the "advanced" world where we have the most mutagens and processed foods.

@GoodScienceForYou Evolution has nothing to do with religion. I am an atheist, one who believes in nothing without proof. Simple life evolved into complex life, and that is a proven fact. Humans have many issues, shitty immunity, cancers, but that is because of the way we live now. We are obese, lazy, soaked in toxins and chemicals. That has nothing to do with evolution.

@cavemantiger Your have listened to this crap of evolution for a long time. It has no evidence and is nothing but a politically driven bullshit. Most people, like you, are lemmings. You can be a free thinker if you want, but once you have your baptism and declare you faith in this religious crap, then your ego is in control of you.

@cavemantiger There is no possible genetic mechanism that has ever caused inceased fitness, nor has any simple life ever evolved into complex life. This religion violates the laws of science.

@cavemantiger The number 6800 is extremely conservative. It is increasing every day. 1 in 10 people have rare diseases. Source NORD. The overall cancer which is a genetic disease from a screwed up immune system, has increased over 110% for all ages since 1982. There is only genetic degradation shown in all DNA studies on humans and any mammals that have been tested. You are just ignorant and not able to understand how do see what is absolutely clear, irrefutable physical evidence.
