Phylogenomics reveals the origin of mammal lice out of Afrotheria
Mammals host a wide diversity of parasites. Lice, comprising more than 5,000 species, are one group of ectoparasites whose major lineages have a...

Did some extinct South American native ungulates arise from an afrothere ancestor? A critical appraisal of Avilla and Mothé’s (2021) Sudamericungulata – Panameridiungulata hypothesis
The debate regarding the evolutionary relationships of the extinct South American native ungulates (SANUs) to the major placental clades Afrotheria...

Molecular characterization of positively selected genes contributing aquatic adaptation in marine mammals
BackgroundMarine mammals, which have evolved independently into three distinct lineages, share common physiological features that contribute to their...

Evolution of the Brain and Sensory Structures in Sirenia
Sirenians represent a striking group of quadruped mammals that are adapted to marine life. There are four extant species of sirenians (three sea cows...

Ancestral chromosomal signatures of Paenungulata (Afroteria) reveal the karyotype of Amazonian manatee (Trichechus inunguis, Sirenia: Trichechidae) as the oldest among American manatees
BackgroundChromosomal painting in manatees has clarified questions about the rapid evolution of sirenians within the Paenungulata clade. Further...

Divergent vertebral formulae shape the evolution of axial complexity in mammals
Complexity, defined as the number of parts and their degree of differentiation, is a poorly explored aspect of macroevolutionary dynamics. The...
