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 ...

Though it accounts for just two percent of the body’s weight, the brain consumes a whopping 20% of its total energy. To get the energy it needs for more complicated tasks, the brain has evolved a ...

Flight is a rare skill in the animal world. Among vertebrates, it evolved only three times: in bats, birds, and the long-extinct pterosaurs. Pterosaurs were the pioneers, taking to the skies more than ...

Researchers from the University of New Hampshire looked at the developmental process of the cerebral cortex—the outermost layer of the brain—and examined how neurons, or nerve cells, refine their ...

A new study in mice describes how the brain rapidly and efficiently increases blood flow to active areas where oxygen and nutrients are needed most. The work shows that the brain relies on a ...

The placenta and the hormones it produces may have played a crucial role in the evolution of the human brain, while also leading to the behavioral traits that have made human societies able to thrive ...

The longer the thumb, the bigger the brain, evolution study suggests By Pranjal Malewar September 07, 2025 The research found the bigger a primate's brain the longer its thumbs were, affirming a ...

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 ...
