First of all, I would like to mention that the fact that all life using the same 4 nucleotides is evidence for common descent, considering there are many more could be used. Along with that, all life uses the same 20 amino acids, when there are also many many more that could have been used, providing very strong support of evolution.I do not believe the argument was about whether there was a creator/designer or what not. But since you mention it...how many amino acids do you suppose were needed for God to create everything? Apparently the 23 we know of were sufficient enough to do the job...
Quote:Now, the similarities in the chromosomes has to do with the proteins and where they are found on the genome. In this case, when we look at the human genome vs the chimpanzee genome, based on the correspondence of different proteins in different locations on different chromosomes, we can show that each human chromosome corresponds to 1 chimpanzee chromosome (because they have the same, or similar, genes coding for the same things at the same location on the protein.Are you aware that proteins only make up less than 1% of the total human genome? Oh and not to mention there are over 3 billion base pairs. So essentially, only 1% of these 3 billion+ base pairs represent protein coding. This means that 99% of the human genome function is noncoding DNA (meaning it doesn't code proteins). If you consider that fact that we only know about 2% of the genome's function and that half of that (1%) is protein coding, then we do not know 99% of the noncoding function. Why is this significant? Scientists making the claims of common descent on the basis of "protein coding similarities" are doing so with only 1% of the 3 billion+ base pairs of the genome and a vast amount of unknown function.
Quote:Again, in summary, each human chromsome can be found to correspond to a chimp chromosome. Now we find that one of our chromosomes (chromosome 2) has fused, when we "take apart" this chromosome we find that each of the pieces corresponds to the pairs of chimp chromosomes we were missing.Well I do believe your explanation is lacking...What chimp chromosomes were we "missing"? All you've done is discuss how proteins in the human genome correspond to ape protein sequence in their genome. But proteins only make up 1% of the genome...what about the other 99%. Keep in mind there are over 3 billion base pairs in the human genome...
I'm sure I'm not very good at explaining this, so let me show you a diagram of chimp and human chromosomes
Quote:This is just a drawing of the chromosomes. Where is the sequence of the over 3 billion base pairs compared next to ape DNA?
the left ones are humans and the right ones are chimps. You can see how similar they are, and how each human chromosme has a corresponding chimp chromosme. You see how we can tell that the 2 parts of the human corresponds to the 2 separate chimp chromosomes.
Quote:Let me emphasize real quick that this need not be the case. If there were a creator he easily could have made the chromosomes in such a way that would render common descent impossible. For example if chromosome 2 existed not as the result of a fusion (ie if we found no extra centromeres and telomeres) then common descent would be destroyed.Again the claim was not about a creator it was about the human/ape evolution claim on the basis of "DNA similarities"...
Besides you still haven't answered my questions about the processes that followed said fusion event (see post #65)
