MACRO COGS MICRO. “The biogeochemical cycles of H, C, N, O and S are coupled via biologically catalysed electron transfer (redox) reactions.” https://lnkd.in/dvRBqTd9 View in LinkedIn

ANALOGY. “Hologenomic evolution is most easily understood by equating a gene in the nuclear genome to a microbe in the microbiome... Evolution for both genes and symbionts is fundamentally a change in population frequency over successive generations, i.e., the fraction of holobionts carrying that particular nuclear allele or microbe.” (Bordenstein and Theis). https://lnkd.in/dk3R9p6y View in LinkedIn

MIGHTY MICROBES. “We have known for many decades that major biogeochemical cycles in the ocean or on land are driven by microbes and that microbes affect animal, human, and plant health directly in many ways, not all negative.” https://lnkd.in/dk3R9p6y View in LinkedIn

UNITS OF SELECTION. “Here, we argue that interaction patterns as entities do in fact vary, pass on traits to later instances of themselves, and differ in propensity to spread and persist; they thus act as units of selection.” https://lnkd.in/dk3R9p6y View in LinkedIn

THE REFRAIN. “Put metaphorically, what matters is the song, not the singer. The song, to flesh out this metaphor, is the pattern of interactions (metabolic, structural, or developmental) between partner lineages (the singers).” https://lnkd.in/dk3R9p6y View in LinkedIn

FUNCTIONAL EVOLUTION. “So, if the idea that microbial consortia are units of selection is to be borne out, it might be better to focus on evolutionary processes at a functional level, not the taxonomic level of partner organisms and their lineages.” https://lnkd.in/dk3R9p6y View in LinkedIn

COMMUNITY COEVOLUTION. “And pairwise, species-on-species coevolution involving a macrobe and hundreds or thousands of microbial lineages independently seems unlikely, if not impossible. There is no obvious mechanism by which the latter could evolve collectively (but see below as to how they might appear to do so).” https://lnkd.in/dk3R9p6y View in LinkedIn

HORIZONTAL GENE TRANSFER. “What primarily undermines this claim, that holobionts (or biofilms) as collectives might be units of selection, is the failure of the lineages they comprise to reproduce as collectives—to exhibit coordinated vertical inheritance.” https://lnkd.in/dk3R9p6y View in LinkedIn

ZERO EMISSIONS FACTORY. “The subduction factory processes raw materials such as oceanic sediments and oceanic crust and manufactures magmas and continental crust as products. Aqueous fluids, which are extracted from oceanic raw materials via dehydration reactions during subduction, dissolve particular elements and overprint such elements onto the mantle wedge to generate chemically distinct arc basalt magmas.” https://lnkd.in/dz8gj2C5 View in LinkedIn
