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

FACULTATIVE ENDOSYMBIOSIS. "Paulinella and its symbionts are mutually interdependent, and neither can replicate independently, indicating that the symbiosis is the result of a transition similar in many respects to eukaryogenesis." http://www.pnas.org/content/112/33/10278.full View in LinkedIn

EXPANDING THE SAMPLE. "Additional genomic exploration among the still largely uncharacterized TACK and DPANN archaea (a newly recognized monophyletic superphylum) cannot but further narrow the prokaryote–eukaryote gap." (TACK = phyla comprising Thaumarchaeota, Aigarchaeota, Crenarchaeota, and Korarchaeota). http://www.pnas.org/content/112/33/10278.full View in LinkedIn

EXAMPLE OF ENDOSYMBIONT. "P. chromatophora "harbors photosynthetic endosymbionts derived from free-living cyanobacteria. The chromatophores are vertically transmitted and partitioned to offspring equitably. There is also substantial genomic integration between host and symbiont as a result of EGT and the invention of protein import machinery." (P= Paulinella). (EGT = external gene transfer). http://www.pnas.org/content/112/33/10278.full View in LinkedIn

EUKARYOTIC HOMOLOGS ANTICIPATED. "We might expect to find closer and closer homologs of components of the several eukaryote-specific cellular machineries [now called eukaryotic signature proteins] as we explore inferred proteomes of such archaea [the group of phyla comprising Thaumarchaeota, Aigarchaeota, Crenarchaeota, and Korarchaeota (TACK)]." http://www.pnas.org/content/112/33/10278.full View in LinkedIn

NOT RARE. "In eukaryotes, endosymbiosis is common." http://www.pnas.org/content/112/33/10278.full View in LinkedIn

ANOTHER RARE STAMP. "Even farther down the organismal path is the two-species bacterial consortium “Chlorochromatium aggregatum,” which has been championed as a model of bacterial multilineage multicellularity. In this symbiosis, green sulfur bacterial epibionts (Chlorobium chlorochromatii) surround a motile β-proteobacterium (Symbiobacter mobilis). The central bacterium relies extensively on the photosynthetic products of its epibionts and has undergone extensive genome reduction, a mark of evolved dependence." https://lnkd.in/d6GwkCt View in LinkedIn

INSECT ELECTROSTATIC CHARGES. "Insects can easily acquire electrostatic charge by walking over charged surfaces or by flying in an airstream of charged particles. Honeybee workers during wintertime conditions can acquire a positive charge of up to 537 pC, whereas honeybees those in non-winter weather can reach up to 200 pC. Positively charged bumblebees can even detect floral electric fields, which ability enhances their foraging success." https://lnkd.in/ddsqgS8 View in LinkedIn

DEEPER LAYER. "It seems that spider dragline is of intelligent character. When acted by a vibrating force with definite frequency, the spider dragline may produce an electric field. Or may it oscillate when subjected to an electric field?" https://lnkd.in/djskEtZ View in LinkedIn

WEB VIBRATIONAL INFORMATION. "Two years ago, a research team led by the University of Oxford revealed that, when plucked like a guitar string, spider silk transmits vibrations across a wide range of frequencies, carrying information about prey, mates and even the structural integrity of a web." Actually, the literature on this subject goes back to 1916. https://lnkd.in/dPt_MVY View in LinkedIn
