Form, function, and evolution of living organisms.
Despite the vast diversity of sizes and shapes of living organisms, life's organization across scales exhibits remarkable commonalities, most notably through the approximate validity of Kleiber's law, the power law scaling of metabolic rates with the mass of an organism. Here, we present a derivation of Kleiber's law that is independent of the specificity of the myriads of organism species. Spe...
متن کاملEvolution of temporal order in living organisms
Circadian clocks are believed to have evolved in parallel with the geological history of the earth, and have since been fine-tuned under selection pressures imposed by cyclic factors in the environment. These clocks regulate a wide variety of behavioral and metabolic processes in many life forms. They enhance the fitness of organisms by improving their ability to efficiently anticipate periodic...
متن کاملGene direction in living organisms
Gene direction, which is important for function, has not been subjected to statistical testing for randomness and for the degree of evolutionary changes. We analyzed 747 sequenced species and 2,061 genomes/ chromosomes and detected clear differences in gene direction between kingdoms. All the archaeans, bacteria, and protozoa analyzed have genes characterized mainly by same-direction neighbors ...
متن کاملLiving Organisms and Environments
In theories of evolution, fitness is the only property of the organism which determines the evolutionary dynamics. The fitness can be described as a function of the genome, but it is more directly related to the phenome. Variations in the fitness as a function of changes in either phenome or genome may sometimes be large and may sometimes be insignificant. Conventional evolutionary theory is, h...
متن کاملLiving Organisms Author Their Read-Write Genomes in Evolution
Evolutionary variations generating phenotypic adaptations and novel taxa resulted from complex cellular activities altering genome content and expression: (i) Symbiogenetic cell mergers producing the mitochondrion-bearing ancestor of eukaryotes and chloroplast-bearing ancestors of photosynthetic eukaryotes; (ii) interspecific hybridizations and genome doublings generating new species and adapti...
