Bear hunting altered genetics more than Ice Age isolation

A recent study published in Molecular Ecology reveals that the genetic distribution of brown bears was not solely determined by Ice Age isolation. Instead, human hunting and land use have had a significant impact on their genetics, allowing them to survive and thrive in central Europe during the coldest periods. This new understanding ...

Rebuilding the evolutionary history of HIV-1 unravels a complex loop

Researchers have developed a new method to reconstruct the evolutionary history of the HIV-1 V3 loop, revealing biologically dependent amino acids that form 'co-evolving' ties across the protein. This study advances understanding of HIV-1 evolution and identifies potential targets for future research.
