Organisms have continued to evolve by accumulating genetic variation while being danced by natural selection. However, a research team at the University of Maine has made the claim that 'human ...

Researchers have demonstrated a specific type of genetic variation in obsessive-compulsive disorder (OCD) for the first time using advanced DNA sequencing technology. The findings support previous ...

Researchers have significantly expanded the catalogue of known human genetic variation. The resulting datasets, shared in two back-to-back publications in the journal Nature, constitute what may be ...

Knowing how human DNA changes over generations is essential to estimating genetic disease risks and understanding how we evolved. But some of the most changeable regions of our DNA have been ...

A new study by researchers at the Max Planck Institute for Evolutionary Biology (MPI-EB) sheds fresh light on one of the most debated concepts in biology: evolvability. The work provides the first ...

Human evolution is like the world’s most difficult puzzle; only small pieces of evidence remain on Earth. These few remains of our predecessors are searched for by many researchers to get a clearer ...

Our genes are inherited from our parents, and the different combinations of these genes make us unique. Genetic inheritance controls the characteristics of all living things. This short video explains ...
