    My question is, why didn’t we know this earlier?

    Mung, yours is a valid question. I don’t know the answer.
    In some cases the recent discoveries could not be done before for technical reasons. In other cases the reductionist bottom-up reverse engineering approach to research could have hindered progress. Perhaps there are other reasons.

    Humans have one fewer pair of chromosomes than do other great apes… Humans have 23 pairs of chromosomes and other great apes have 24 pairs of chromosomes…
    Apparently, in the human evolutionary lineage, two ancestral ape chromosomes fused at their telomeres, producing human chromosome…

    So what’s the problem? Let’s fuse the chromosomes in one of the great apes in the lab and see if the ape starts speaking, develops the ability of abstract thoughts, looks for the purpose in life and universe, questions injustice, develops feelings only known in men, starts worshiping anything, develops math, builds a boat, a plane, a telephone, a house an a/c, a watch, a contraceptive, a gun, a banana peel remover and so on… Then evolution will be falsified beyond any doubt…

    Genomic monkey business—estimates of nearly identical human–chimp DNA similarity re-evaluated using omitted data

    by Jeffrey Tomkins and Jerry Bergman

    A review of the common claim that the human and chimpanzee (chimp) genomes are nearly identical was found to be highly questionable solely by an analysis of the methodology and data outlined in an assortment of key research publications. Reported high DNA sequence similarity estimates are primarily based on prescreened biological samples and/or data.

    ….

    Several recent research reports confirm the conclusions noted above.

    While the recent Y-chromosome comparison between human and chimp does not lend itself to a genome-wide similarity estimate, the extreme dissimilarity discovered is an insurmountable paradox for common ancestry in primate evolution because it is by far the least variable chromosome in the human genome.

    “While the recent Y-chromosome comparison between human and chimp does not lend itself to a genome-wide similarity estimate, the extreme dissimilarity discovered is an insurmountable paradox for common ancestry in primate evolution because it is by far the least variable chromosome in the human genome.”

    Old news, but was mostly ignored when it came out.

    Opinions?

    We did. See:

    So I guess my next question is, what’s wrong with cherry-picking your data?
