Biologists are closing in on a puzzle that seems to turn classic evolutionary logic inside out, yet may be so common that it ...

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 ...

The analysis revealed that about 2 per cent of sperm from men in their early 30s contained disease-causing mutations. That ...

Researchers discover that insect sex systems influence the speed of mitochondrial evolution, impacting biodiversity tracking ...

The centromere is necessary for the transport of chromosomes during cell division and, therefore, for the correct ...

Groundbreaking research shows that as men age, harmful genetic mutations in sperm become more common—not just from random chance, but because some are naturally favored. Advanced sequencing revealed ...

A groundbreaking study published in this week’s issue of PNAS by scientists from Israel and Ghana shows that an evolutionarily significant mutation in the human APOL1 gene arises not randomly but more ...

Research on SARS-CoV-2 in zoo tigers, lions, and hyenas shows rapid viral evolution and adaptation, offering insights into cross-species transmission dynamics.

A new gene editor takes advantage of CRISPR-associated proteins to insert whole genes into the genome, scientists report. When you purchase through links on our site, we may earn an affiliate ...
