Abstract
III.a-1.) Trends in Specializations of Prokaryotic Extremophiles
If the Archaea evolved on Earth as the Bacteria were evolving on Mars, and there was occasional cross-contamination which intensified during the LHB, then we should expect extremophiles which specialize in tolerating spacial extremes, like cold, drouth, low pressure, radioactivity, hyperacceleration and hypergravity, to be found mostly among the Bacteria, while extremophiles among the Archaea should be expected more often to specialize in tolerating decidedly planetary extremes such as heat, high pressure, acidity, salinity, and alkalinity.
II.a-1A.) Adaptations to Terrestrial Extremes
III.a-1Aα.) Acidophiles & Hyperacidotolerant, Near-Acidophilic Neutriphiles
This group includes organisms capable of thriving in hyperacidic conditions, most of which have an optimal growth pH of 5 or lower (OGpH<5), although a few have an OGpH slightly above this (e.g., Nanoarchaeum equitans, OGpH=6) but can nonetheless be found flourishing in hyperacidic environments (pH=0.5-1.5).

"Nitrosotalea is an abundant, globally distributed genus of AOA found in acidic soils (Gubry-Rangin et al., 2011). Thirty per cent of the world's soils are considered acidic (pH < 5.5; von Uexküll & Mutert, 1995), and ammonia oxidation in low pH soils is dominated by AOA, rather than AOB (Gubry-Rangin et al., 2010; Lehtovirta-Morley et al., 2011)."

III.a-1D.) Limitations on Methodology
General and special counts performed with described genera and species are necessarily problematic, for several reasons:
1.
|
Species and genera are largely arbitrary, especially in prokaryotes.
|
2.
|
The number of genera and species can change.
|
3.
|
Performing the count is difficult. Even under ideal circumstances (i.e., a perfect, non-arbitrary, universally applicable criterion for determining taxonomic rank, complete genomic knowledge of every living organism on the planet, phylogenies already well-determined and described in the published literature, and every species' tolerances and optimal growth conditions studied in painstaking detail and accurately described) it would be a monumental task to sift through and pore over the seemingly infinite number of papers, journal articles, and books published on the subject in order to count every genus and species ever described.
|
4.
|
General and special counts might not mean much. Even under ideal circumstances and with a complete count performed, it's questionable how useful this information would truly be. Bacteria seem to have inhabited the planet for at least 3.5 GA. There has been ample opportunity for Archaea and Bacteria to adapt to every conceivable condition on this planet, so these tendencies could be mere coincidence. While some groups of Archaea and Bacteria certainly appear to contain preponderances of certain varieties of extremophile, many of these adaptations co-evolved in diverse lineages, and are not always indicative of common ancestry. Additionally, genes involved in "planetary" extremophily seem in some cases related to genes involved in "spacial" extremophily. Furthermore, many of these genes were acquired via LGT (Fuchsman, &al. 2017; Herbold et al., 2017).
|
The conceit here is that the "overal theme" regarding which domain seems to be better at adapting to certain sorts of extremes is indicative, in a very general way, of evolutionary history.
