“…As recently claimed by Boto (2014), there is increasing evidence for the role of horizontal gene transfer in the acquisition of novel traits. This has been shown in animals as different as sponges, cnidarians, rotifers, nematodes, molluscs and arthropods.…”

“…R. Soc. B 371: 20150443 in a predecessor material's components that leads to a qualitative change in its physical properties [92], by horizontal gene transfer bringing in a new ingredient [93], or as a side-effect of gradual evolution for something else [94], it will immediately entail a characteristic, and in some cases unprecedented, set of morphogenetic possibilities. Highly disparate phenotypic outcomes of a developmental system containing this new material can be adjacent to one another in the system's dynamical space [95], implying that one form can change into another with no intermediates.…”

‘Biogeneric’ developmental processes: drivers of major transitions in animal evolution

One contribution of 13 to a theme issue 'The major synthetic evolutionary transitions'. Using three examples drawn from animal systems, I advance the hypothesis that major transitions in multicellular evolution often involved the constitution of new cell-based materials with unprecedented morphogenetic capabilities. I term the materials and formative processes that arise when highly evolved cells are incorporated into mesoscale matter 'biogeneric', to reflect their commonality with, and distinctiveness from, the organizational properties of non-living materials. The first transition arose by the innovation of classical cell-adhesive cadherins with transmembrane linkage to the cytoskeleton and the appearance of the morphogen Wnt, transforming some ancestral unicellular holozoans into 'liquid tissues', and thereby originating the metazoans. The second transition involved the new capabilities, within a basal metazoan population, of producing a mechanically stable basal lamina, and of planar cell polarization. This gave rise to the eumetazoans, initially diploblastic (twolayered) forms, and then with the addition of extracellular matrices promoting epithelial-mesenchymal transformation, three-layered triploblasts. The last example is the fin-to-limb transition. Here, the components of a molecular network that promoted the development of species-idiosyncratic endoskeletal elements in gnathostome ancestors are proposed to have evolved to a dynamical regime in which they constituted a Turing-type reaction-diffusion system capable of organizing the stereotypical arrays of elements of lobe-finned fish and tetrapods. The contrasting implications of the biogeneric materialsbased and neo-Darwinian perspectives for understanding major evolutionary transitions are discussed.This article is part of the themed issue 'The major synthetic evolutionary transitions'.

“…for HGT seems to have attenuated in the radiation of the Eucarya, particularly among the animals, although evidence is increasing that it is more prevalent than previously thought (Boto, 2014). Because we now know that the most common mode of acquisition of traits occurs by HGT in Bacteria and Archaea, we can no longer use the 'Modern Synthesis' to describe the genetic basis of evolution.…”

Giving microbes their due – animal life in a microbially dominant world

The new technology of next-generation sequencing is changing our perceptions of the form and function of the biological world. The emerging data reveal an array of microbes that is more vast and more central to all biological processes than previously appreciated. Further, evidence is accumulating that the alliances of microbes with one another and with constituents of the macrobiological world are critical for the health of the biosphere. This contribution summarizes the basic arguments as to why, when considering the biochemical adaptations of animals, we should integrate the roles of their microbial partners.
