“…Like other evolutionary developments in genetics and microbiota, pawnobe studies could be applied to agriculture (Thrall et al, 2011 ). Additionally, pawnobiome host interactions may provide insights for biological theories [e.g., autocenosis and democenosis (Savinov, 2011 ) symbiogenesis (Mereschkovsky, 1909 ; Kozo-Polyansky, 1924 ), synergistic selection (Corning and Szathmáry, 2015 ), teleonomy (Corning, 2014 ), endophyte studies (Taghavi et al, 2009 ), and the hygiene hypothesis (Strachan, 2000 )]. Purposeful and cautious artificial selection could have broad ranging applications within biotechnology, health care, and evolutionary biology.…”

“…The evolutionary history of animals spans 600 million years, and over its course no animal has evolved independently of symbiotic microbes 1 2 . Instead, each animal has maintained intimate associations with microbial symbionts that have likely had profound effects on the animal's biology 1 2 3 . Associations between animals and their symbiotic microbes can certainly be antagonistic, but many appear to be mutualistic.…”

Symbiotic microbes can benefit their animal hosts by enhancing the diversity of communication signals available to them. The fermentation hypothesis for chemical recognition posits that 1) fermentative bacteria in specialized mammalian scent glands generate odorants that mammals co-opt to communicate with one another, and 2) that variation in scent gland odors is due to underlying variation in the structure of bacterial communities within scent glands. For example, group-specific social odors are suggested to be due to members of the same social group harboring more similar bacterial communities in their scent glands than do members of different social groups. We used 16S rRNA gene surveys to show that 1) the scent secretions of spotted hyenas are densely populated by fermentative bacteria whose closest relatives are well-documented odor producers, and that 2) these bacterial communities are more similar among hyenas from the same social group than among those from different groups.

“…Our bodies must be understood as holobionts whose anatomical, physiological, immunological and developmental functions evolved in shared relationships of different species (Zilber- Rosenberg and Rosenberg 2008). Thus, the holobiont, with its integrated community of species, becomes a unit of natural selection whose evolutionary mechanisms are largely unexplored (Savinov 2011). Indeed, if the incorporation of new participants, with novel genetic and physiological properties, into evolving holobionts has been a common evolutionary strategy, some major tenets of the Modern Synthesis may need re-evaluation.…”

Symbiosis as the way of eukaryotic life: The dependent co-origination of the body

Molecular analyses of symbiotic relationships are challenging our biological definitions of individuality and supplanting them with a new notion of normal part-whole relationships. This new notion is that of a 'holobiont', a consortium of organisms that becomes a functionally integrated 'whole'. This holobiont includes the zoological organism (the 'animal') as well as its persistent microbial symbionts. This new individuality is seen on anatomical and physiological levels, where a diversity of symbionts form a new 'organ system' within the zoological organism and become integrated into its metabolism and development. Moreover, as in normal development, there are reciprocal interactions between the 'host' organism and its symbionts that alter gene expression in both sets of cells. The immune system, instead of being seen as functioning solely to keep microbes out of the body, is also found to develop, in part, in dialogue with symbionts. Moreover, the immune system is actively involved in the colonization of the zoological organism, functioning as a mechanism for integrating microbes into the animal-cell community. Symbionts have also been found to constitute a second mode of genetic inheritance, providing selectable genetic variation for natural selection. We develop, grow and evolve as multi-genomic consortia/teams/ecosystems.
