Humans and chimpanzees both acquire genetic mutations at the rate of 50-100 base pair changes per generation. This has been observed and tested. That is the rate needed to account for the difference in our DNA if we were the same species 3-5 million years ago.
Coincidence? I think not.

Firstly, it is important to realize that natural sciences are very difficult to grasp. I've battled my way though all and chemistry, physics and biology are painful to learn. Oddly enough, of the three main natural sciences, biology is the easiest (objectively I dare say) as phemistry and physics are both highly reliant on complex mathematics (more so physics). Regardless, one can be explained the basic principals underlying most aspects of biology, excluding biochemistry, quite easily -- all it takes is a willingness to listen and learn -- no mathematical brain required. Now, I believe I'm correct in assuming most persons here understand what genes do. They control near-all aspects of an organism. There are the phenotypes (what you actually can see with your eyes) and genotypes (what is there on the gene). For the sake of the explanation, we'll focus on the latter as the former is simply the immediate result. The reproductive organs in humans take what is known as a diploid cell, with a full 46 chromosomes, containing all of the genes, and, through a process known as meiosis, turn that cell into a haploid cell with twenty-three chromosomes. It is this method that allows human beings to reproduce, sexually; 23 from the father + 23 from the mother = new human being. This process, that of meiosis, is not perfect, however and that truly is a blessing. If the process was perfect -- first off, there'd be no DNA, period -- mutations would never occur. We would all be the same but, moreover, we would have never evolved. It is because we are imperfect that we came to be -- it's almost poetic. The majority of the time, these errors are bad, and harm the organism but sometimes, they turn out to be helpful. In the wild, animals, humans included, produce far more offspring than they need -- some of these could have genetic mutations and often times they'll die because of this. However, it's like throwing spaghetti against a wall -- some of it is bound to stick. If you produce a large amount of offspring, the higher the chances of more spaghetti sticking. This is known as Evolution by Natural Selection. Now, this would usually ensure that only the good mutations make it though, but sometimes it's not so clear. The dysbindin-1 gene (DTNBP1) is linked to greater intelligence, but also schizophrenia. The HBB gene, which is associated with sickle cell anemia (causing unending exhaustion), can actually help you survive being bitten by a mosquito carrying malaria. Sometimes, however, a process known as Sexual Selection becomes involved. One such case would be blue eyes. While nearly universally understood to be ascetically pleasing, the rate of macular degeneration (causes blindness) is higher in blue-eyed individuals while blue eyes offer no real survival advantage. In short, "bad mutations" can also be a double edged sword, attached to bad circumstances, or are carried on into future generations for irrational reasons, i.e., sexual preference. All of this corrupts the genome but corruption isn't necessarily a bad thing. The CCR5 gene, which might be responsible for resistance to HIV-1, is, assuming it does provide resistance to HIV-1, helpful and a mutation. Over a long period of time, these corruption build up and the result is evolution -- the gradual development of something. The over all theme is positive, but yes, the imperfect way by which we reproduce, does bring along some junk. Philosophically, that says a lot to me but this is a scientific question. I apologize if I went too in depth, but you asked a very purposeful question that deserves not an ideological response, but one grounded in fact and reality. For the record though: small changes + lots of time = evolution. Meiosis can be proven to produce changes + the earth can be proven to be c.4.5 billion years (as well as the very old hominoid fossil record) = evolution is a fact beyond reasonable doubt. Cheers! Brayden.

These are human scientific designations that have nothing really to do with the diversity of species in animals...we pick an attribute and assign it to the creature and then cubby hole them into genus catagories and try to family them up. The problem is this phylem spectrum...you have mammals, reptiles, amphibians, fowl. Some of each have their life on land and some in the water...the spectrum is too large and too vast for any human to attempt to associate them altogether. That is one of the issues that evolution cannot resolve...if we evolved from primates then what did primates evolve from? A cheetah is a large cat and a tiger is an even larger cat...just like my house cat is a small domestic...well, house cat. A chimp is a primate. A human is a human and one of a kind. We have our own genetic blueprint and they all have theirs. You really should look into some writings and research regarding the molecular machines of DNA and also the "theory" of irreducible complexity. Love in Christ, ~J~
Consider if you will these strange creatures and the genes they might have in common..with???
Platypus
Kangaroo
Bats
Butterflies
Bears
They, say that the Giant Panda is more directly related to the Racoon than the bear...yeah. Okay.

I'm reading an interesting book that is talking about the genetic differences from chimpanzee and humans are so small we should probably both be classified under the genus Homo. The only reason we don't is because we treat ourselves differently. We have far more divergent animals classified under the same genus than humans and chimpanzees but we don't want to consider any other animal close to us since it starts bringing up serious ethical issues.

I think it's possible that god created man through evolution. Genesis was written by people thousands of years ago and they explained it the best way they could.

"in his own image"? I guess he's got 46 chromosomes too, since two pairs of chromosomes fused from *his* ape ancestors, too.

God created us in his own image and at the same time we descended from monkeys, a true contradiction like any science.

Nope.
I do not take every word in Genesis literally, but one basic truth it teaches is that God created man in His own image.
