Even before the publication of Darwin's Origin of Species, the perception of evolutionary
change has been a tree-like pattern of diversification-with divergent branches spreading …

New insights in the speciation process and the nature of “species” that accumulated in the
past decade demand adjustments of the species concept. The standing of some of the most …

“Natural selection can preserve innovations, but it cannot create them. Nature's many
innovations—some uncannily perfect—call for natural principles that accelerate life's ability …

Here we report associations between secondary metabolite production and phylogenetically
distinct but closely related marine actinomycete species belonging to the genus Salinispora …

Antibiotic resistance is a field in which the concept of One Health can best be illustrated. One
Health is based on the definition of communication spaces among diverse environments …

The late 19th century was the beginning of bacterial taxonomy and bacteria were classified
on the basis of phenotypic markers. The distinction of prokaryotes and eukaryotes was …

Asexuals are an important test case for theories of why species exist. If asexual clades
displayed the same pattern of discrete variation as sexual clades, this would challenge the …

Integrating and conjugative elements (ICEs) are one of the three principal types of self-
transmissible mobile genetic elements in bacteria. ICEs, like plasmids, transfer via …

Genetic exchange by conjugation is responsible for the spread of resistance, virulence, and
social traits among prokaryotes. Recent works unraveled the functioning of the underlying …

Conjugation of DNA through a type IV secretion system (T4SS) drives horizontal gene
transfer. Yet little is known on the diversity of these nanomachines. We previously found that …
