We propose the cooperative model of phenotype-driven evolution, in which natural selection operates on a phenotype caused by both genetic and epigenetic factors. The conventional theory of evolutionary synthesis assumes that a phenotypic value (P) is the sum of genotypic value (G) and environmental deviation (E), P=G+E, where E is the fluctuations of the phenotype among individuals in the absen...
Innate lymphoid cells (ILCs) have been classified into "functional subsets" according to their transcription factor and cytokine profiles. Although cytokines, such as IL-12 and IL-23, have been shown to shape plasticity of ILCs, little is known about how the tissue microenvironment influences the plasticity, phenotype, and function of these cells. Here, we show clearly demarcated tissue specifi...
BACKGROUND In culture, isogenic mammalian cells typically display enduring phenotypic heterogeneity that arises from fluctuations of gene expression and other intracellular processes. This diversity is not just simple noise but has biological relevance by generating plasticity. Noise driven plasticity was suggested to be a stem cell-specific feature. RESULTS Here we show that the phenotypes o...
This paper analyzes the complexity of a new phenotype for evolvable hardware with more plasticity than the traditional phenotype. The plasticity is due to that fact that this phenotype is unstructured and that property allows it to perform combinational and sequential tasks. The complexity is evaluated in relation to Shannon’s limit (lower) and Lupanov’s limit (upper). These limits define a b...
