MESSY HYBRID. "Is the eukaryotic cell best seen as a kind of community composed of two or three taxonomically divergent entities or as a genuine individual that can be part of an evolving population of similar things? Should the answer have an impact on biological theory?" http://www.pnas.org/content/112/33/10278.full View in LinkedIn

EXPECT THE IMPROBABLE. "However, combinatorial improbability is how evolution works: that eukaryotes arose is not unique in its uniqueness." http://www.pnas.org/content/112/33/10278.full View in LinkedIn

LAUGHINGLY IMPROBABLE. "The combinatorial stringing together of all of the steps between LECA and Macropus rufus (the red kangaroo), Trichomonas vaginalis, or Mozart is, indeed, laughably improbable. Surely, if life’s tape was rewound, none of these would recur." (LECA = ). http://www.pnas.org/content/112/33/10278.full View in LinkedIn

RIDDLES OF FORM "The waves of the sea, the little ripples on the shore, the sweeping curve of the sandy bay between the headlands, the outline of the hills, the shape of the clouds, all these are so many riddles of form." (D'Arcy Wentworth Thompson 1986-1948). https://lnkd.in/daEGKJJ View in LinkedIn

MESSY BOLT-ONS. "A patchy prokaryotic distribution of preeukaryotic features is what advocates of rampant LGT as a crucial evolutionary process should expect." (LGT = Lateral gene transfer). http://www.pnas.org/content/112/33/10278.full View in LinkedIn

FRAGMENT FROM NATURE this next two weekends continues with the topic of spider web geometry, structure and function. That such small creatures can be so smart has been confounding, until the recent finding that in some small spiders, their central nervous system actually occupies ~80% of their body cavity and a quarter of their keg cavities, in contrast to other insects. https://lnkd.in/dDxNxEX View in LinkedIn

HOMOLOGS WILL CHANGE THE STORY. "One might predict a future day in which no steps (inventions or mechanisms) entailed in whatever is then the prevailing theory of eukaryogenesis are not found as homologs or reasonably matching analogs in one or another prokaryotic lineage." http://www.pnas.org/content/112/33/10278.full View in LinkedIn

REDUCTIVE ANALYSIS. "All features of the macro-structure of the orb-webs shown can be explained by mechanical and biological constraints." Lovely analysis of mechanics of spider webs. https://lnkd.in/ddG4UHk View in LinkedIn

SPIDER GENE CODING. "Engineering mechanics and heuristics rely on the prescient power of mathematics and natural laws which give finalistic guidance for inventing structures. Good theory guarantees good machines and webs too. Thus the spider must have a very ingenious theory programmed to its genes." https://lnkd.in/dYdY4x3 View in LinkedIn

TYPES OF INFORMATION. "Nature is full of hierarchical and symbiotic structures which are optimally designed in all design aspects. Ingenious solutions in nature are transmitted by genetic codes. Human information is not transferable genetically but has to be studied, stored to design codes and transmitted by education." https://lnkd.in/dYdY4x3 View in LinkedIn
