Emergence of life: from functional RNA selection to natural selection and beyond.
This study tracks the rise, evolution and post-evolution of the genetic information system through emergence of life. The major stages traversed include prebiotic synthesis, functional RNA selection by metabolite, RNA World, peptidated RNA world, co-evolution of genetic code and amino acid biosynthesis, last universal common ancestor, Darwinian evolution and synthetic life.
متن کاملGplusE: beyond genomic selection
GplusE is a strategy for genomic selection in which the accuracy of assessment in the reference population for a primary trait such as yield is increased by the incorporation of data from high- throughput field phenotyping platforms. This increase in precision comes from both exploiting genetic relationships between traits and reducing the effect of environmental influences upon them. We descri...
متن کاملNatural selection
The time-scale of evolution Think of the 3.5 billion years that makes the history of life on earth as stretching for a single year. On the first of January, there is nothing more than primitive bacteria, and this remains the case for the next eight months. Multicellular eukaryotic life appears in early September, vertebrates invade the land at the beginning of December and dinosaurs become exti...
متن کاملNatural Language and Natural Selection
Many people have argued that the evolution of the human language faculty cannot be explained by Darwinian natural selection. Chomsky and Gould have suggested that language may have evolved as the by-product of selection for other abilities or as a consequence of as-yet unknown laws of growth and form. Others have argued that a biological specialization for grammar is incompatible with every ten...
متن کاملBeyond Core Knowledge: Natural Geometry
For many centuries, philosophers and scientists have pondered the origins and nature of human intuitions about the properties of points, lines, and figures on the Euclidean plane, with most hypothesizing that a system of Euclidean concepts either is innate or is assembled by general learning processes. Recent research from cognitive and developmental psychology, cognitive anthropology, animal c...
