Insights into Land Plant Evolution Garnered from the Marchantia polymorpha Genome.
The evolution of land flora transformed the terrestrial environment. Land plants evolved from an ancestral charophycean alga from which they inherited developmental, biochemical, and cell biological attributes. Additional biochemical and physiological adaptations to land, and a life cycle with an alternation between multicellular haploid and diploid generations that facilitated efficient dispersal of desiccation tolerant spores, evolved in the ancestral land plant. We analyzed the genome of the liverwort Marchantia polymorpha, a member of a basal land plant lineage. Relative to charophycean algae, land plant genomes are characterized by genes encoding novel biochemical pathways, new phytohormone signaling pathways (notably auxin), expanded repertoires of signaling pathways, and increased diversity in some transcription factor families. Compared with other sequenced land plants, M. polymorpha exhibits low genetic redundancy in most regulatory pathways, with this portion of its genome resembling that predicted for the ancestral land plant. PAPERCLIP
From wise humanising creativity to (post-humanising) creativity
This is the author accepted manuscript. The final version is available from Palgrave Macmillan (Springer) via the DOI in this record.This chapter demonstrates that the concepts of creativity in education put forward to
date can only go so far in addressing the rapid, unpredictable changes inherent in the
21st century and the accompanying policy and practice challenges we face. The
chapter shifts away from conceptualisation such as ‘wise humanising creativity’ and
proposes a different articulation of creativity which may allow us to think about and
action creativity to meet these challenges. This (post-humanising) creativity
overcomes problems of humanistic conceptualisations as it allows for a full range of
‘players’ within the creative process, it incorporates a different, emergent take on
ethics and is willing to see the future too as emergent, rather than always ‘to-bedesigned’.
The chapter culminates by offering examples of (post-humanising)
creativity in action, aiming to bring alive how it can address our policy and practice
dilemmas.In writing this chapter, I would like to acknowledge the support and critical friendship
