Dynamical Patterning Modules, Biogeneric Materials, and the Evolution of Multicellular Plants
Frontiers in Plant Science, 2018 Comparative analyses of developmental processes across a broad spectrum of organisms are required to fully understand the mechanisms responsible for the major evolutionary transitions among eukaryotic photosynthetic lineages (defined here as the ...

Convergent Evolution During Local Adaptation to Patchy Landscapes. [PDF]
PLoS Genetics, 2015 Species often encounter, and adapt to, many patches of similar environmental conditions across their range. Such adaptation can occur through convergent evolution if different alleles arise in different patches, or through the spread of shared alleles by

Differential evolution with thresheld convergence [PDF]
2013 IEEE Congress on Evolutionary Computation, 2013 During the search process of differential evolution (DE), each new solution may represent a new more promising region of the search space (exploration) or a better solution within the current region (exploitation). This concurrent exploitation can interfere with exploration since the identification of a new more promising region depends on finding a ...

FEBS Letters, EarlyView.Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Parallel vs. Convergent Evolution in Domestication and Diversification of Crops in the Americas
Frontiers in Ecology and Evolution, 2018 Domestication involves changes in various traits of the phenotype in response to human selection. Diversification may accompany or follow domestication, and results in variants within the crop adapted to different uses by humans or different agronomic ...

Convergent evolution of the annual life history syndrome from perennial ancestors
Frontiers in Plant Science, 2023 Despite most angiosperms being perennial, once-flowering annuals have evolved multiple times independently, making life history traits among the most labile trait syndromes in flowering plants.

Evolution: Convergent Pathways to Symbiosis [PDF]
Current Biology, 2020 Little is known about the establishment of symbioses. A new study finds that two independent protist-algae symbioses utilize convergent patterns of nutrient exchange, suggesting that certain complementary host and symbiont traits can increase the likelihood of establishing beneficial symbiotic interactions.

Divergence and Convergence in Enzyme Evolution [PDF]
Journal of Biological Chemistry, 2012 Comparative analysis of the sequences of enzymes encoded in a variety of prokaryotic and eukaryotic genomes reveals convergence and divergence at several levels. Functional convergence can be inferred when structurally distinct and hence non-homologous enzymes show the ability to catalyze the same biochemical reaction.

The human gut microbiome across the life course
FEBS Letters, EarlyView.Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.
