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 ...

Some mammals hibernate to survive in winter, but the Eurasian common shrew (Sorex araneus) employs Dehnel's phenomenon to get ...

For a long time, evolutionary biologists have thought that the genetic mutations that drive the evolution of genes and proteins are largely neutral: they're neither good nor bad, but just ordinary ...

A QUT-led study has found how increasing aridity and habitat variation and the subsequent emergence of grasslands shaped the ...

The field of molecular epidemiology has brought a transformative perspective to the study of viral infections by integrating molecular data and phylogenetic ...

ANN ARBOR—For a long time, evolutionary biologists have thought that the genetic mutations that drive the evolution of genes and proteins are largely neutral: they're neither good nor bad, but just ...

The molecular clock theory posits that genetic changes happen steadily and gradually, offering a reliable means for peering into the past and theorizing when complex life first emerged. However, there ...

A major evolutionary theory says most genetic changes don’t really matter, but new evidence suggests that’s not true. Researchers found that helpful mutations happen surprisingly often. The twist is ...

Abstract:Professor Hirotoshi Mori (Department of Applied Chemistry, Faculty of Science and Engineering, Chuo University), together with Nichika Ozawa ...

Molecular evolution investigates the processes that drive changes in genetic material over time. It encompasses the generation of mutations—whether through DNA replication errors, damage or other ...
