Evolutionary Kuramoto dynamics

open access: yesProceedings of the Royal Society B: Biological Sciences, 2022
Biological systems have a variety of time-keeping mechanisms ranging from molecular clocks within cells to a complex interconnected unit across an entire organism. The suprachiasmatic nucleus, comprising interconnected oscillatory neurons, serves as a master-clock in mammals. The ubiquity of such systems indicates an evolutionary benefit that outweighs

The evolution of convex trade-offs enables the transition towards multicellularity

open access: yesNature Communications, 2021
Multicellularity is a major evolutionary transition that remains poorly characterized at the ecological and genetic level. Exposing unicellular green algae to a rotifer predator showed that just 500 generations of predator selection were sufficient to ...

Developmental fates of shark head cavities reveal mesodermal contributions to tendon progenitor cells in extraocular muscles

open access: yesZoological Letters, 2021
Vertebrate extraocular muscles (EOMs) function in eye movements. The EOMs of modern jawed vertebrates consist primarily of four recti and two oblique muscles innervated by three cranial nerves. The developmental mechanisms underlying the establishment of

Developmental Evolution of Hypaxial Muscles: Insights From Cyclostomes and Chondrichthyans

open access: yesFrontiers in Cell and Developmental Biology, 2021
Jawed vertebrates possess two distinct groups of muscles in the trunk (epaxial and hypaxial muscles) primarily defined by the pattern of motor innervation from the spinal cord.

A common gene drive language eases regulatory process and eco-evolutionary extensions

open access: yesBMC Ecology and Evolution, 2021
Background Synthetic gene drive technologies aim to spread transgenic constructs into wild populations even when they impose organismal fitness disadvantages. The extraordinary diversity of plausible drive mechanisms and the range of selective parameters

Novel developmental bases for the evolution of hypobranchial muscles in vertebrates

open access: yesBMC Biology, 2020
Background Vertebrates are characterized by possession of hypobranchial muscles (HBMs). Cyclostomes, or modern jawless vertebrates, possess a rudimentary and superficial HBM lateral to the pharynx, whereas the HBM in jawed vertebrates is internalized and

Experimental evolution of a pheromone signal

open access: yesEcology and Evolution, 2022
Sexual signals are important in speciation, but understanding their evolution is complex as these signals are often composed of multiple, genetically interdependent components.

Evolutionary dynamics in structured populations [PDF]

open access: yesPhilosophical Transactions of the Royal Society B: Biological Sciences, 2010
Abstract Evolutionary dynamics shape the living world around us. At the centre of every evolutionary process is a population of reproducing individuals. The structure of that population affects evolutionary dynamics. The individuals can be molecules, cells, viruses, multicellular organisms or humans.

Stepwise participation of HGF/MET signaling in the development of migratory muscle precursors during vertebrate evolution

open access: yesZoological Letters, 2018
Background The skeletal musculature of gnathostomes, which is derived from embryonic somites, consists of epaxial and hypaxial portions. Some hypaxial muscles, such as tongue and limb muscles, undergo de-epithelialization and migration during development.

Evolutionary algorithms and dynamic programming [PDF]

open access: yesProceedings of the 11th Annual conference on Genetic and evolutionary computation, 2009
Recently, it has been proven that evolutionary algorithms produce good results for a wide range of combinatorial optimization problems. Some of the considered problems are tackled by evolutionary algorithms that use a representation which enables them to construct solutions in a dynamic programming fashion.
