  • They are transcription factors that use a particular DNA binding motif called a homeobox, and they are found in clusters and expressed colinearly.

  • Stelnicki EJ, Komuves LG, Holmes, Clavin W, Harrison MR, Adzick NS, Largman C: The human homeobox genes MSX-1, MSX-2, and MOX-1 are differentially expressed in the dermis and epidermis in fetal and adult skin.

  • It now appears that the homeobox control mechanism for the production of segmented bodies evolved among organisms that were not segmented.

  • So, would the homeobox regulation of metamerism be considered as a "front-loaded" pre-adaptation?

  • If it turns out that there are other possible mechanisms but that the homeobox regulatory mechanism was the least costly evolutionary speaking for primitive animals with out metamerism then MET gains additional plausibility

  • IF it turns out that the ancestral homeobox regulatory mechanism was extravagant it would make FLE more likely

  • If they developed using the same regulatory mechanism as shrimp (they are all segmented arthropods, after all), the production of segmented appendages using a relatively slight modification of the homeobox program for segmented bodies would produce exactly that: "mouth-arms" that look a lot like shrimp.

  • In Gould's concept of the term, the original homeobox regulatory mechanism would have evolved first in non-metameric animals, and then become modified later in the dominant metameric forms (i.e. arthropods and vertebrates).
