    Of related interest to this video on ontogenetic depth (the fact that embryonic mutations are, by far, the least likely to be tolerated), Dr Nelson did another talk on ORFan genes:

    Widespread ORFan Genes Challenge Common Descent – Paul Nelson – video with references in description

    Genomes of similar species – Cornelius Hunter PhD.
    Excerpt: Different variants of the Escherichia coli bacteria, for instance, each have hundreds of unique genes. And some of these genes have been found to have important functions, such as helping to construct proteins. [8]
    Massive genetic differences were also found between different fruit fly species. The fruit fly is one of the most intensely researched organisms and in recent years a systematic study of the genomes of a dozen different species was undertaken. Evolutionists were surprised to find novel features in the genomes of each of these different fruit fly species. Thousands of genes showed up missing in many of the species, and some genes showed up in only a single species. [9] As one science writer put it, “an astonishing 12 per cent of recently evolved genes in fruit flies appear to have evolved from scratch.” [10] These so-called novel genes would have had to have evolved over a few million years—a time period previously considered to allow only for minor genetic changes. [11,12] ,,, etc.. etc…

    From Jerry Coyne, More Table-Pounding, Hand-Waving – May 2012
    Excerpt: “More than 6 percent of genes found in humans simply aren’t found in any form in chimpanzees. There are over fourteen hundred novel genes expressed in humans but not in chimps.”
    Jerry Coyne – ardent and ‘angry’ neo-Darwinist – professor at the University of Chicago in the department of ecology and evolution for twenty years. He specializes in evolutionary genetics.

    how ORFan genes relates to ontogenetic depth is that ORFan genes are found to be expressed very early in embryonic development:

    New genes in Drosophila quickly become essential. – December 2010
    Excerpt: The proportion of genes that are essential is similar in every evolutionary age group that we examined. Under constitutive silencing of these young essential genes, lethality was high in the pupal (later) stage and (but was) also found in the larval (early) stages.

    Age doesn’t matter: New genes are as essential as ancient ones – December 2010
    Excerpt: “A new gene is as essential as any other gene; the importance of a gene is independent of its age,” said Manyuan Long, PhD, Professor of Ecology & Evolution and senior author of the paper. “New genes are no longer just vinegar, they are now equally likely to be butter and bread. We were shocked.”

    New Genes, New Brain – October 2011
    Excerpt: “This is one of the first studies to look at the role of completely novel genes” in primate brain development,,, A bevy of genes known to be active during human fetal and infant development first appeared at the same time that the prefrontal cortex,,, Finally, 54 of the 280 genes found to be unique to humans were also highly expressed in the developing prefrontal cortex,,,, “We were very shocked that there were that many new genes that were upregulated in this part of the brain,” said Long, who added that he was also taken aback by synchronicity of the origin of the genes and the development of novel brain structures.,,, (From the PLoS article, author’s summary: We found these genes are scattered across the whole genome, demonstrating that they are generated by many independent events,,, Our data reveal that evolutionary change in the development of the human brain happened at the protein level by gene origination,,)

    This was a well done speech by a creationist who does well in presentation and this because he intimately understands the issues.
    It was always impossible that selection could create new bits and pieces to create the glory of biology.
    I don’t think selection has ever done very much or had much time anyways buty turning one type of butterfly into another type of butterfly in the Amazon does not lead to turning it into a armadillo.
    Mutations or no mutations.
    If evolutions confidence is based on the prediction of mutations being zillions of times johnny-on-the-spot then its over folks. Put a fork in it.
