Cognition: from Unicellular Organisms to Humans
Brian Charlesworth (Edinburgh University) concluded that the two major evolutionary problems were the “origin of life” and the “evolution of human consciousness and cognition.” Toward the latter issue, this chapter traces a path linking the molecular origins of adaptive behaviors in unicellular organisms to the synaptic mechanisms of human cognition and its medical disorders. This framework has...

متن کاملThe Evolution of COP9 Signalosome in Unicellular and Multicellular Organisms.
The COP9 signalosome (CSN) is a highly conserved protein complex, recently being crystallized for human. In mammals and plants the COP9 complex consists of nine subunits, CSN 1-8 and CSNAP. The CSN regulates the activity of culling ring E3 ubiquitin and plays central roles in pleiotropy, cell cycle, and defense of pathogens. Despite the interesting and essential functions, a thorough analysis o...
متن کاملScaling of energy metabolism in unicellular organisms: a re-analysis.
The database used by Hemmingsen (1960) to compute energy metabolism in unicellular organisms was reassembled and submitted to linear (log-log) analysis. As Hemmingsen noted, this data set includes marine zygotes, which are not unicellular organisms. If no temperature correction factors are applied to the data the best-fit regression line has a slope of 0.698 +/- 0.024. Application of the temper...
متن کاملCodon usage and tRNA content in unicellular and multicellular organisms.
Choices of synonymous codons in unicellular organisms are here reviewed, and differences in synonymous codon usages between Escherichia coli and the yeast Saccharomyces cerevisiae are attributed to differences in the actual populations of isoaccepting tRNAs. There exists a strong positive correlation between codon usage and tRNA content in both organisms, and the extent of this correlation rela...
