The lack of a strict relationship between genome size and organismal complexity (level of organization) is largely due to size variability of the facultative part of the genome. However, there is a direct relationship between the level of organization and the minimal genome size (MGS) in the lineage leading from prokaryotes to mammals, in which the tendency towards increasing complexity is especially clear. The dynamics of MGS in this lineage can be adequately described by the model of… Expand

Components of Intrageneric Genome Size Dynamics in Plants and Animals
TLDR
Genome size dynamics of diploids and polyploids within plant genera can significantly differ which reflects influence of different evolutionary factors and can increase, decrease, or remain relatively stable during the entire time of genus evolution. Expand
Genome Size Dynamics within Multiple Genera of Diploid Seed Plants
TLDR
It is concluded that genome size within the genera of many diploid seed plant species is not stochastic and follows a linear dependence on the evolutionary age of the species. Expand
Complication of Animal Genomes in the Course of the Evolution Slowed Down after the Cambrian Explosion
For the first time, the growth rate of minimal animal genome size is shown to slow down in the course of evolution from prokaryotic forms to mammals after the Cambrian explosion. There is proposed anExpand
A bird-like genome from a frog: Mechanisms of genome size reduction in the ornate burrowing frog, Platyplectrum ornatum
TLDR
The data show that this frog evolved molecular mechanisms to keep in check a major process characterizing large genomes: namely, proliferation of transposable elements, and offers a model for future comparative studies on mechanisms of genome size reduction in amphibians and vertebrates generally. Expand
Genome Size Covaries More Positively with Propagule Size than Adult Size: New Insights into an Old Problem
TLDR
It is shown that genome size correlates more positively with egg size than adult size in crustaceans, which should also apply to single-celled eggs and other reproductive propagules with relatively few cells that are pivotal first steps in their lives. Expand
Coenzyme world model of the origin of life
TLDR
It is argued that primordial life had no nucleic acids; instead heritable signs were represented by isolated catalytically active self-reproducing molecules, similar to extant coenzymes, which presumably colonized surfaces of oil droplets in water. Expand
Once More about Aspects, Directions, General Patterns and Principles of Evolutionary Development.
The present volume is the fourth issue of the Almanac series entitled ‘Evolution’. Thus, one can maintain that our Almanac, which has actually turned into a Yearbook, has succeeded (see below). TheExpand
Comparative analysis of genomic sequence dependent and sequence-independent approaches to identify RNA editing sites in human primary monocytes / Leong Wai Mun
TLDR
This is the first study that utilized both genomic-dependent and genomic-independent sequence approaches to identify RNA editing sites using high-depth genomic and transcriptomics datasets, and results obtained showed that majority of the editing sites resided in the non-coding regions. Expand
Evo-SETI: A Mathematical Tool for Cladistics, Evolution, and SETI
TLDR
The Evo-SETI Theory is a mathematical way to face the problem of where each new exoplanet stands along its way to develop life as the authors know it on Earth and the Peak-Locus Theorem is extended to any mean value other than the exponential. Expand
About the Singularity in Biological and Social Evolution
Using mathematical modeling, we consider the phenomenon of singularity in the biological and social history. It is shown that hyperbolic trends in biological and social evolution can be explained byExpand

Genome increase as a clock for the origin and evolution of life
TLDR
The increase of functional non-redundant genome size in macro-evolution was consistent with the exponential hypothesis, and the possibility of panspermia as a source of life on earth should be discussed on equal basis with alternative hypotheses of de-novo life origin. Expand
Genome evolution and the evolution of exon-shuffling--a review.
TLDR
Analyzing the evolutionary distribution of modular proteins that have clearly evolved by intronic recombination suggests that exon-shuffling acquired major significance at the time of metazoan radiation. Expand
The Origins of Genome Complexity
TLDR
It is argued that many of these modifications emerged passively in response to the long-term population-size reductions that accompanied increases in organism size, and provided novel substrates for the secondary evolution of phenotypic complexity by natural selection. Expand
A genomic timescale of prokaryote evolution: insights into the origin of methanogenesis, phototrophy, and the colonization of land
TLDR
Early time estimates for methanogenesis support the consideration of methane, in addition to carbon dioxide, as a greenhouse gas responsible for the early warming of the Earths' surface and support most of the currently recognized higher-level groupings of prokaryotes. Expand
The modulation of DNA content: proximate causes and ultimate consequences.
TLDR
There is increasing evidence for the primacy of selection in molding genome sizes via impacts on cell size and division rates and processes inducing quantum or doubling series variation in gametic or somatic genome sizes are common. Expand

TLDR
The results reported by Nilsson et al. (1) in this issue of PNAS indicate how such transformations proceed and help to explain one of the most interesting and pervasive trends in the evolution of bacterial genomes. Expand
Insertion-deletion biases and the evolution of genome size.
TLDR
The mutational equilibrium model is found to be problematic, and it is noted that DNA loss by small indels is too slow in real time to determine variation in genome size above a relatively low threshold. Expand
Genome of the marsupial Monodelphis domestica reveals innovation in non-coding sequences
TLDR
A high-quality draft of the genome sequence of the grey, short-tailed opossum is reported, indicating a strong influence of biased gene conversion on nucleotide sequence composition, and a relationship between chromosomal characteristics and X chromosome inactivation. Expand
Macroevolution, hierarchy theory, and the C-value enigma
TLDR
Genome size evolution provides a clear example of hierarchy in action and therefore lends support to the theoretical approach of macroevolutionists, and it is apparent that genome evolution cannot be understood without such a hierarchical approach, thereby providing an intriguing conceptual link between the most reductionistic and expansive subjects of evolutionary study.

Origin of avian genome size and structure in non-avian dinosaurs
TLDR
The results indicate that the small genomes typically associated with avian flight evolved in the saurischian dinosaur lineage between 230 and 250 million years ago, long before this lineage gave rise to the first birds. Expand
