Convergent Evolution and the Epigenome [PDF]

Epigenomes
Background: Trait convergence or parallelism is widely seen across the animal and plant kingdoms. For example, the evolution of eyes in cephalopods and vertebrate lineages, wings in bats and insects, or shark and dolphin body shapes are examples of ...

The emergence and ongoing convergent evolution of the SARS-CoV-2 N501Y lineages

Cell, 2021
The independent emergence late in 2020 of the B.1.1.7, B.1.351, and P.1 lineages of SARS-CoV-2 prompted renewed concerns about the evolutionary capacity of this virus to overcome public health interventions and rising population immunity.

High-Altitude Drives the Convergent Evolution of Alpha Diversity and Indicator Microbiota in the Gut Microbiomes of Ungulates

Frontiers in Microbiology, 2022
Convergent evolution is an important sector of evolutionary biology. High-altitude environments are one of the extreme environments for animals, especially in the Qinghai Tibet Plateau, driving the inquiry of whether, under broader phylogeny, high ...

Convergent evolution of berberine biosynthesis. [PDF]

Sci Adv
Berberine is an effective antimicrobial and antidiabetic alkaloid, primarily extracted from divergent botanical lineages, specifically Coptis (Ranunculales, early-diverging eudicot) and Phellodendron (Sapindales, core eudicot).

Convergent evolution in human and domesticate adaptation to high-altitude environments

Philosophical Transactions of the Royal Society B: Biological Sciences, 2019
Humans and their domestic animals have lived and thrived in high-altitude environments worldwide for thousands of years. These populations have developed a number of adaptations to survive in a hypoxic environment, and several genomic studies have been ...

Convergent molecular evolution of phosphoenolpyruvate carboxylase gene family in C4 and crassulacean acid metabolism plants [PDF]

PeerJ, 2022
Phosphoenolpyruvate carboxylase (PEPC), as the key enzyme in initial carbon fixation of C4and crassulacean acid mechanism (CAM) pathways, was thought to undergo convergent adaptive changes resulting in the convergent evolution of C4 and CAM ...

Beyond RuBisCO: convergent molecular evolution of multiple chloroplast genes in C4 plants [PDF]

PeerJ, 2022
Background The recurrent evolution of the C4 photosynthetic pathway in angiosperms represents one of the most extraordinary examples of convergent evolution of a complex trait.

Complementary evolution of coding and noncoding sequence underlies mammalian hairlessness

eLife, 2022
Body hair is a defining mammalian characteristic, but several mammals, such as whales, naked mole-rats, and humans, have notably less hair. To find the genetic basis of reduced hair quantity, we used our evolutionary-rates-based method, RERconverge, to ...

How (some) mammals lost their hair

eLife, 2022
An approach that allows scientists to identify regions of the genome that evolved faster in hairless mammals reveals candidate genetic mechanisms that gave rise to hairlessness.

Convergent Evolution in SARS-CoV-2 Spike Creates a Variant Soup from Which New COVID-19 Waves Emerge

International Journal of Molecular Sciences, 2023
The first 2 years of the COVID-19 pandemic were mainly characterized by recurrent mutations of SARS-CoV-2 Spike protein at residues K417, L452, E484, N501 and P681 emerging independently across different variants of concern (Alpha, Beta, Gamma, and Delta)
