The dominant species on Planet X is, like us, exoskeletal in structure, with a strong centralized information/analytic core operating over numerous individual foraging operative units, again like our own configuration. This should not be surprising, as all of our projections have strongly suggested that this is optimal for species to progress intellectually. This species, or more accurately, array of species, in the native taxonomy, is designated Blatta or Blatella, colloquially cockroach.
However, there are several other life structures more or less successful on the planet, most of them part of the Blattoid survival system, but still of interest in their own right. The closely associated Homo genus is particularly fascinating, as it has developed a kind of neuronal autonomy, all while fulfilling its primary function as Blattoid food aggregator. This neatly illustrates the principal of progress within dominance driving progress among subordinates as well. The benefits trickle down, as it were.
This group is a part of a large subgroup of life that has internalized skeletal structures, strange as it may seem that such an adaptation could survive the rigors of planetary change. No doubt it was successful only due to its usefulness to the more abundant exoskeletal populations. The internalization process appears to have been more general as well, since most species live outside the protective and nourishing saline water environment; they have evolved a means of carrying these essentials within them. Not terribly efficient, one might argue, but there they are. Indeed, the Blattoids themselves largely live outside water, as well.
Homo is a very homogeneous genus, having survived a major killing episode some 2,000 generations earlier as a single breeding population, or at most 2-3 such populations in close contact. The only extant species is the sapiens sapiens variety, others having died out. As a result of the extremely short breeding history since geographic expansion, they are a remarkably uniform species genetically, differing only by tenths of a percent. Nevertheless, much appears to be made of such trivial differences as can be identified, perhaps as a mechanism to evolve to accommodate diverse Blattoid species; more study is required, since this tendency is dysfunctional.
Perhaps the most curious attribute of Homo is the complete decentralization of species intelligence. Instead, each individual carries its own ideational complex built upon a central nervous system; so specific is this center, that if the head, where it is located, is removed, the individual immediately shuts down, and is therefor incapable of fulfilling its role in the species from that instant.
The explanation, of course, of such an unlikely array of evolutionary elements is in the role of Homo in service to Blattoids. Such extreme self-containment suddenly makes sense when seen as a response to the diverse situations in which roach populations find themselves; with primary food aggregators able to act spontaneously and autonomously to procure proper Blattoid habitats, any unforeseen problems can be easily averted.
The committee hopes this study will be helpful in making full contact with the dominant intelligent species on planet X; it may well be simplest to proceed through the intermediation of their Homo servants, as unpalatable as that may seem. Actually, though, they may be quite palatable, once their usefulness to us is ended.
