A new Yale study provides a fuller picture of the genetic changes that shaped the evolution of the human brain, and how the process differed from the evolution of chimpanzees. For the study, published ...

If we look across the whole of the mammal branch of the tree of life, we find there are many groups of mammals that have evolved testicles of all different sizes. In almost all these separate cases, ...

Share on Pinterest Human brain cell evolution may be linked to autism, neurodiversity, according to a new study. Image credit: Lauren Lee/Stocksy A new study concludes that the speed at which the ...

For decades, scientists have known that bacteria can exchange genetic material, in a process called horizontal gene transfer. This allows bacteria to rapidly evolve new traits, such as antibiotic ...

A new paper in Molecular Biology and Evolution, published by Oxford University Press, finds that the relatively high rate of Autism-spectrum disorders in humans is likely due to how humans evolved in ...

A newly discovered genetic mutation unique to humans may help explain why we are significantly more vulnerable to cancer than our closest evolutionary relatives. Researchers at the University of ...

The human body is a machine whose many parts – from the microscopic details of our cells to our limbs, eyes, liver and brain – have been assembled in fits and starts over the four billion years of our ...

It has been claimed that because most of our DNA is active, it must be important, but now human-plant hybrid cells have been ...

Humans, who are classified among the five great apes, are closest genetically, i.e., DNA similarity, to chimpanzees (98.8%-99%) and bonobos (98.8%). [Blueringmedia ...
