  • As any of these authors will agree, the HGT's role is insignificant in multicellular organisms.

  • Guts: Many unicellular eukaryotes were multifunctional cells, doing many different things, however these became specialized in multicellular organisms.

    Biomolecular Networks

  • Many unicellular eukaryotes were multifunctional cells, doing many different things, but specialized in multicellular organisms.

    Biomolecular Networks

  • The more precursors we find, and the more specific they seem to be — so that their functions in multicellular organisms would not be easily replaced by other components — the more difficult it is to accept a non-teleological origin.

    A Tetrahymena Puzzle

  • IOW, if a gene vital in multicellular life forms is present and highly conserved in single-cell life forms (in which it isn't expressed or perform any other vital function), we could conclude that the gene was front-loaded into the genome by a designer of the original genome with the expectation that multicellular life forms would evolve when that gene does get expressed.

    Another predictable argument against front-loading

  • For example, this is true for developmental biology and for analysis of the functions of signalling pathways in multicellular organisms.

  • Since such a creature as the rabbit is formed through the co-operation of a vast multitude of cells, it is called multicellular; the amoeba, on the other hand, is unicellular.

  • I think that a similar thing to #2 has already happened, only with a particular kind of multicellular animal that we on earth call "spiders". what's new online!

  • If we discovered a more advanced life-form, such as some kind of multicellular organism, that would eliminate a much larger set of evolutionary transitions from consideration as the Great Filter.

  • However, almost as soon as multicellularity arose, it "exploded", producing the fantastic diversity of multicellular animals, plants, and fungi that we see today and in the fossil record of the Phanerozoic.
