Was sagst Du denn zu den oben beigefügten Quellen zum resilienzfördernden Sinn von Viren? 
Ich sehe uns als [https://www.ncbi.nlm.nih.gov/pubmed/24568029|Holobionten], und dazu gehört der innere biologische Dialog :-) (-:

Zitat:
"Integrated viral DNA in the host genome are endogenous viral elements (EVEs), which have the __potential to drive evolutionary processes__, such as speciation, resulting in the emergence of new traits (44–46). In addition to these evolutionary transitions, EVE integration can affect gene expression through their long terminal repeats (LTRs). These LTRs are repetitive viral DNA sequences that flank integrated EVEs, serving as promoters to both viral and host genes. These __LTRs can affect stem cells (47), development (48), and immunity (49, 50).__ There are many individual genes affected by EVEs, though their major impact on evolutionary traits may be on gene regulatory networks, or the cellular regulators that impact RNA and protein expression (51, 52). __The effects of EVEs and transposable elements in all these biological processes are being recognized as vitally important__ (53).

Genomically integrated viral elements are reminders that __viruses affect everything in biology,__ but what about free viruses that associate with hosts? Viromics allow researchers to analyze the viral populations and effects these viruses have on the holobiont. These studies have been conducted in many host systems, from the base of animal life in the Cnidarian phylum (54) to mammals (55). 
Often, the viruses found freely associating are prokaryotic viruses, which regulate the number and strains of bacteria in a holobiont (56). These __viruses are likely selected by the host to maintain bacterial populations __(26). Further, viromics show the sphere of viral involvement in gene flow and gene shuffling in an ever-changing environment, often from within bacterial cells and sometimes from within eukaryotic cells."
