Genome-scale data and the development of novel statistical phylogenetic approaches have
greatly aided the reconstruction of a broad sketch of the tree of life and resolved many of its …

Over the past decades, there have been tremendous efforts to understand the cross-talk
between viruses and host metabolism. Several studies have elucidated the mechanisms …

Incomplete lineage sorting (ILS) makes ancestral genetic polymorphisms persist during
rapid speciation events, inducing incongruences between gene trees and species trees. ILS …

Laboratory studies have demonstrated that a single phenotype can be produced by many
different genotypes; however, in natural systems, it is frequently found that phenotypic …

When challenged by similar environmental conditions, phylogenetically distant taxa often
independently evolve similar traits (convergent evolution). Meanwhile, adaptation to extreme …

Collateral sensitivity is an evolutionary trade-off whereby acquisition of the adaptive
phenotype of resistance to an antibiotic leads to the nonadaptive increased susceptibility to …

Within the next decade, the genomes of 1.8 million eukaryotic species will be sequenced.
Identifying genes in these sequences is essential to understand the biology of the species …

Understanding the mechanisms underlying species formation and differentiation is a central
goal of evolutionary biology and a formidable challenge. This understanding can provide …

Biologists have long been intrigued by apparently predictable and repetitive evolutionary
trajectories inferred across a variety of lineages and systems. In recent years, high …

Microbial diversification is driven by geographic and ecological factors, but how the relative
importance of these factors varies among species, geographic scales, and habitats remains …
