Summary: This study provides evidence supporting the hypothesis that wingless females of stem ants in the Cretaceous period were cooperators. The research also suggests that the presence of winged and wingless forms may have been an ancestral trait in the entire clade of ants, and highly specialized worker-specific phenotypes evolved independently in stem ants and crown ants. Additionally, the use of high-resolution micro-computed tomography (μCT) scans allowed for the analysis of the internal anatomy of the stem ants.

Summary: This article examines the rate at which reversible phenotypic plasticity (RPP) occurs and its potential impact on how organisms overcome environmental challenges. The study suggests that current theoretical models do not consider the evolutionary potential of RPP rates. If the rate of plasticity itself can evolve, it may alter the organism's perception of environmental predictability and influence the slope of the evolved reaction norm. The optimization of phenotypic plasticity rates, their evolutionary dynamics in different environments, and the costs associated with them warrant further exploration in future research.

Summary: Scarce evidence suggests that important evolutionary developments for jawed vertebrates may have taken place during or prior to the Silurian period. Fossil discoveries unveil insights into this particular interval.

Summary: In trait-based ecology, it is common to use measures to quantify phenotypic variation between populations. However, these measures overlook the within-population trait variability and some of them cannot be partitioned between populations. This study proposes a new measure called the phenotypic dissimilarity (PhD) index to address these issues and provide a tool for quantifying phenotypic variation within and between species.

Summary: This study proposes a theoretical framework for immune cell phenotypic classification based on gene plasticity, and suggests that loss and gain of phenotype are accompanied by changes in gene plasticity. Transcriptome data analysis from multiple immune cell types supports the logical rationality and generality of this framework, providing a new perspective on understanding diverse immune cell phenotypes and intrinsic regulation in the immune system. Moreover, the results obtained provide a useful resource for big-data-driven experimental studies and knowledge discoveries.

Summary: Research shows that European eels belong to a single panmictic population with no geographical genetic differentiation. The predominant mechanism for European eels to respond to diverse environmental conditions is phenotypic plasticity rather than genetic adaptation.

Summary: The study investigates the relationship between phenotypic plasticity and integration, finding that while plasticity is positively associated with integration in both environments, this relationship is influenced by phenotypic variation. Differences in plastic responses may involve a major reorganization of trait relationships, challenging the idea that stress generally induces a tighter phenotype.
