Ahh, confirmation bias at its finest. But really, couldn't you make this claim about anything? Imagine that I compared you to a dog turd. You might think that you're not that similar to a dog turd, but wait... you're both composed of atoms bound together into molecules, contain DNA, contain a lot of carbon, are primarily water, were issued from a living being, controlled by the laws of nature, exposed to the sun on a daily basis, destined to be buried some day, completely clueless, etc. I'm sure I could go on for days about the similarities between you both. However, when it was first suggested that pigs and humans were alike, I googled DNA similarities pigs humans and came up with
http://www.abc.net.au/science/articles/2010/05/03/2887206.htm in which I read:
"Depending upon what it is that you are comparing you can say 'Yes, there's a very high degree of similarity, for example between a human and a pig protein coding sequence', but if you compare rapidly evolving non-coding sequences from a similar location in the genome, you may not be able to recognise any similarity at all. This means that blanket comparisons of all DNA sequences between species are not very meaningful."
So, in short, I'm not very convinced that humans and pigs are that different. But then again, I don't think that Chinese and Koreans look that similar nor do I think that Guatemalans look similar to Mexicans. I know there are a lot of people, in the United States especially, who cannot tell the difference between them. However, I always figured that those people were ignorant and unperceptive.
