From a long-term perspective, only ecosystem with a fully integrated nutrient cycle is alive. The lack of trophic autonomy should be considered one of the key factors that ensure and maintain biodiversity. The variability of abiotic conditions, both in space and in time, also creates a huge diversity of niches and subniches for genotypes and species. In addition, life maintains its essential variables (biomass and productivity) as stable as possible due to the diversity of structures (genes, macromolecules, metabolic pathways, genotypes, species, etc.): the structures that reach optima are multiplied and thus activated, while the functioning of those which lost their optima is suppressed. The facts and concepts presented in this monograph thus support the conclusions that (a) genotype and species diversity is supported by trophic specialisation (b) biodiversity helps to stabilise the functions (essential variables) of individuals, populations, and ecological communities (c) the emergence of biodiversity is determined by heritable variation and the advantage of specialised (more effective) structures over non-specialised ones (d) biodiversity is characterised by its ability to increase itself and to organise itself into relatively consistent structures, which we call production pyramids and nutrient cycles. This book therefore provides an answer to the question "why the diversity of life is of such and such a nature". 606 $aEvolution (Biology) 606 $aLife$xOrigin 606 $aEvolutionary genetics 606 $aSpecies 606 $aEvolutionary Theory 606 $aOrigin of Life 606 $aEvolutionary Genetics 606 $aSpeciation 615 0$aEvolution (Biology) 615 0$aLife$xOrigin. 615 0$aEvolutionary genetics. 615 0$aSpecies. 615 14$aEvolutionary Theory. 615 24$aOrigin of Life. 615 24$aEvolutionary Genetics. 615 24$aSpeciation. 676 $a333.740684 676 $a577 700 $aLeki?avichi?us$b E?$g(E?dmundas),$084800 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910595061603321 996 $aBiodiversity$92915678 997 $aUNINA
