Phylogenetics and molecular evolution lie at the heart of understanding the origins and diversification of life. By constructing phylogenetic trees, scientists map the evolutionary relationships ...

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and severe acute respiratory syndrome coronavirus (SARS-CoV) are members of the subgenus Sarbecovirus, whose genomic length is around ...

An Australian study conducted at the University of Melbourne describes that the emergence of more deadly variants of concern (VOCs) of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is ...

Caves are perceived as isolated, extreme habitats with a uniquely specialized biota, which long ago led to the idea that caves are “evolutionary dead-ends.” This implies that cave-adapted taxa may be ...

Just as bird watchers may use binoculars to add to their species lists, scientists interested in bird evolution may use computational tools to clarify avian lineages. Indeed, such tools have enabled ...

A recent paper provides an updated perspective on the evolutionary history of chelicerates—a diverse and ecologically significant group of arthropods that includes spiders, scorpions, mites, and ...

A new study challenges traditional views on arachnid evolution, suggesting that the transition from water to land occurred multiple times rather than in a single event. The research also highlights ...

The journal Science China Life Sciences published a study reported by Academician Hang Sun’s group from Kunming Institute of Botany, Chinese Academy of Sciences. The research team demonstrated the ...

Brain size differs substantially among species, and several hypotheses have been proposed to explain the evolution of brain size. Because the brain is among the most energetically expensive organs in ...

Understanding the evolution of insect mating behavior is essential for explaining how early insects adapted to life on land.
