Life is a chemical reaction. Three major transitions in early evolution are considered without recourse to a tree of life. The origin of prokaryotes required a steady supply of energy and electrons, probably in the form of molecular hydrogen stemming fro
Compressibility of plasma flow is generally expected to be realized in a cosmological context. For example, a recent analysis by Giovannini [163, 164] has argued that, due to adiabatic inhomogeneities of the scalar curvature, the cosmic plasma flow at large scales could be compressible in the pe...
at least in large part, by evolutionary changes made to the cerebral cortex. This paper reviews the biology and evolution of mammalian cortical radial glial cells (primary neural stem cells) and introduces the concept that a genetically step wise process, based on a core molecular pathway already...
The coding sequences of the C domain are conserved with respect to its exonic location, except for Ciona and Drosophila where the C domain begins with the third exon. The A domain is encoded by a sequence within the first exon; the only exception is found in Ciona and Drosophila synapsins...
The co-existence of males, females and hermaphrodites, a rare mating system known as trioecy, has been considered as an evolutionarily transient state. In nematodes, androdioecy (males/hermaphrodites) as found in Caenorhabditis elegans, is thought to have evolved from dioecy (males/females) throu...
Using the platinum-based mutational signature as a barcode, we determine that the clonal expansion originating the secondary AMLs begins after the start of the cytotoxic treatment. Its absence in clonal hematopoiesis cases is consistent with the start of the clonal expansion predating the exposure to...
Here the process begins with invasion of the petiole glands, followed by intracellular establishment within the meristematic cells of this tissue [60, 78]. The symbioses of cyanobacteria with their plant partners differ remarkably from the rhizobia-legume interactions. First, cyanobacteria show a broad...
Whatever most people think evolutionary is for the most part a pure parody14 of the evolutionist's opinion. But a more serious error than all these pervades what we may call the drawing-room view of the evolutionist theory. So far as Society with a big initial is concerned, evolutionism ...
(representing haplotypes), and links which connect the nodes in the shortest possible tree. The size of the nodes is proportional to the number of chromosomes with a given haplotype, and the colors within haplotypes (or nodes) indicate the frequency of that haplotype in pooled populations (such...
Most people familiar with evolutionary theory will also be familiar with the mantra that “Nothing in biology makes sense except in the light of evolution” [1]. At the same time, it continues to be a challenge to situate evolutionary theory in the curriculum in such a way that it can act...
