    Pursuant to several evolutionary discussions on this subforum, the following recent article may be of some interest. There are evidently many more animal-like genes in the alga Chlamydomonas than many of us assumed.

    “Although Chlamydomonas is certainly more plant than animal, there are clear similarities between this photosynthetic organism and animals that would surprise the average person on the street,” comments Grossman. “Just twenty years ago no one would have guessed that an alga would have retained many of the functions we associate with humans and would be useful for developing a basic understanding of certain human diseases.”

    More than 100 scientists have reported an analysis of the genome of the green alga Chlamydomonas reinhardtii in the October 12 issue of the journal Science.

    And the genome has been deposited in the Joint Genome Institute's database:


    (a short tutorial: Following this last link, one can select BLAST (Basic Local Alignment Search Tool) and input any sequence of interest, for example the sequence of some human disease gene. This will compare the input sequence to the genome of the organism that you are blasting against (in this case, Chlamydomonas). There are other tools on the site. The Joint Genome Institute is a public resource for genomic research.)

    Evolutionists often make the point, for instance, the in many genes each human male is more closely related to chimpanzee males than either is to the females of their species. And the same applies the other way too. Sex is so old that genes for it have their own 'lineage' as it were, that doesn't necessarily follow species lines.

    The proteins and neurochemistry of those algae may be a similar "legacy" perchance? Or have they simply been misclassified thus far?
