    My Top 10 List

    Here are a few of the available examples and reviews: Evidence for transit peptide acquisition through duplication and subsequent frameshift mutation of a preexisting protein gene in rice Minoru Ueda Masaru Fujimoto, Shin-ichi Arimura, Nobuhiro Tsutsumi, Koh-ichi Kadowaki. Molecular Biology...

    Endogenous retroviruses (ERVs) Why should I care?

    The key is the difference between Active retroviruses - that can cause new copies to be inserted into the genome and Inactive retroviruses - that can no longer cause new copies to be inserted into the genome - but they are still there and can be detected. That ERV are nearly extinct means that...

    religious belief and natural selection

    The problem is that religion is not reliant on a single system in the brain but many different systems working together each of which evolved for a different purpose. It could easily be that religion in itself has no adaptive value. Because "religious thought and behavior are based on quite...

    How widespread is plasticity?

    Yes, people who study phenotypic plasticity do: "The high potential fitness benefit of phenotypic plasticity tempts us to expect phenotypic plasticity as a frequent adaptation to environmental heterogeneity. Examples of proven adaptive plasticity in plants, however, are scarce and most plastic...

    The MYTH of Random Mutations

    Actually we know what mutation caused the wrinkled pea trait that mendel studied was: "The wrinkled-seed character of pea described by Mendel is caused by a transposon-like insertion in a gene encoding starch-branching enzyme. Cell. 1990 Jan 12;60(1):115-22. Bhattacharyya MK, Smith AM, Ellis...

    The MYTH of Random Mutations

    The mutations mentioned are highly likely to be random as all the available evidence indicates that this is the only type of mutation that has been shown to exist. There is not a single experiment that proves non random (with respect to function) mutation, therefore your assertion that the...

    Cavemen

    Check out this amusing website: http://www.thestoneage.org/ which claims 'cavemen' did not exist and there never was a stone age. Its by Islamic creationist Harun Yahya, but there is very little difference between Islamic creationsis and christian creationists - Harun Yahya copied most of his...

    Evolution continuing to happen in humans?

    Lactase persistance is one example and the gene has very strong signatures of recent (~5,000-10,000 years) selection: Genetic Signatures of Strong Recent Positive Selection at the Lactase Gene Todd Bersaglieri et. al. Am. J. Hum. Genet., 74:1111-1120, 2004...

    ancient bird - modern bird transitional found

    Its also worth noting that Gansus was found exactly when you would expect if evolution was true. This is exactly like Tiktaalik, as far as i am aware there is no creationist explanation for this type of confirmation of evolution.

    Comparative genomics: a practical application of common descent

    This article looks quite good: Genomics of the evolutionary process Andrew G. Clark TRENDS in Ecology and Evolution (in press) http://dx.doi.org/10.1016/j.tree.2006.04.004 (DOI doesn't work yet) Abstract: Comparative analysis of genome sequences has become the primary means by which...

    Fossil Fish Sheds Light on Transition

    Yet more proof thats its not about truth just creationists trying to justify their belief that they would hold no matter what. No evidence can convince the creation fanatic because their belief is not based on evidence.

    Nature and Tetrapods

    Ooo can't wait, Per and Matin B have been dropping hints about this for ages at IIDB. By the way Martin Brazeau (one of the authors of the forthcoming paper) has a nice post on his blog 'the lancelet' on the background to this discovery and how geology paleontology and evolution can work...

    Insertion Hotspots?

    Members of the HERV-K family is still active and shared with the other apes, there are several other types of retroviruse that are present but not active, this means they can be detected and used for phylogenetic analysis. They may no longer be commonly active, this is very different being no...

    A Map of Recent Positive Selection in the Human Genome

    This is fascinating research and nicely compliments this paper that appeared recently in PNAS: 'Global landscape of recent inferred Darwinian selection for Homo sapiens': http://www.pnas.org/cgi/content/short/103/1/135 (free full text) Also check out the editorial in PLOS biology 'Being...
