ORIGIN OF LIFE. “The emergence of life was probably marked by a transition in information processing capabilities.” http://rsif.royalsocietypublishing.org/content/10/79/20120869 View in LinkedIn

DIGITAL TRANSITION. “Purely analogue life forms could have existed in the past but are not likely to survive over geological timescales without acquiring explicitly digitized informational protocols. Therefore, life forms that ‘go digital’ may be the only systems that survive in the long-run and are thus the only remaining product of the processes that led to life.” https://lnkd.in/ewsT9EQ View in LinkedIn

INFORMATION THEORY. “We have presented a framework for understanding the origin of life as a transition in causal structure, and information management and control, whereby information gains causal efficacy over the matter it is instantiated in.” http://rsif.royalsocietypublishing.org/content/10/79/20120869 View in LinkedIn

DOWNSIZING GAMETOGENESIS. "During the course of evolution, the gametophytic phase of the plant life cycle, which is dominant in bryophytes (i.e. liverworts, hornworts and mosses), has been dramatically reduced to only a few cells in the angiosperms (flowering plants)." https://lnkd.in/ewV3vWP View in LinkedIn

"LOGIC is not a substitute for data; and substantial data are lacking for many aspects of polyploid evolution." https://lnkd.in/eee56_B View in LinkedIn

SPOROGENESIS IN PLANTS. "The formation of the plant reproductive lineages proceeds in two distinct phases: during sporogenesis, spores are formed by sporophytic (somatic) cells, whereas during gametogenesis the spores develop into mature gametophytes that harbour the male or female gametes." https://lnkd.in/ewV3vWP View in LinkedIn

STRESS TOLERANCE. "Allopolyploids may also endure environmental change better than autopolyploids, because the former may marshal more genetic resources through genome reorganization and greater flexibility in gene expression to cope with immediate stresses." https://lnkd.in/eee56_B View in LinkedIn

PROMISCUOUS HYBRIDS. "When pollinated by facultative apomictic tetraploids, the offspring generated were frequently fertile and highly sexual tetraploid hybrids. This was observed in a fixed setting, but is evidently occurring in nature due to the extensive variability within tetraploid populations that are associated with diploid colonies." http://libres.uncg.edu/ir/asu/f/Mueller,%20Marissa%20Thesis.pdf View in LinkedIn

FRESH TERRITORIES. "Polyploids with two or more genomes seem especially adept at colonizing habitats which are beyond the tolerances of their progenitors. An establishment advantage might also accrue for allopolyploids when neoautoploids have lower fertilities than neoalloploids." https://lnkd.in/eee56_B View in LinkedIn

CHAOTIC FUSIONS. "Diploids often produce cytologically unreduced female gametes, these unreduced gametes can fuse with normal haploid gametes (pollen) to generate triploid hybrids and, even more rarely, fuse with other unreduced gametes to produce tetraploids (having four copies of a single genome)." http://libres.uncg.edu/ir/asu/f/Mueller,%20Marissa%20Thesis.pdf View in LinkedIn
