"the Development of the human ability to communicate with the help of the facial muscles went hand in hand with the changes of our face shape. It concludes a group of researchers who believe that this non-verbal communication has been crucial for our species survival."
"Joy, sorrow, surprise, or suspicion, – almost the whole of the human känsloregistret going to see in our faces. To be able to convey these in a proper way has played a significant role for our species survival, which in turn has shaped how our faces looks like."
"It says a group of researchers from several countries in the journal Nature, Ecology and Evolution after having gone through the existing research in the field."
"the Human head shape, and then in front of all our faces, have undergone a dramatic change over the last millennia. Unlike our now extinct relatives, like the neanderthalarna, our faces, relatively short, without that we would have given compromising on brain volumes. Also other relatives, like chimpanzees and bonobos, looks strikingly different than what we humans are doing today."
"in the Past, the focus has been almost exclusively on environmental factors, such as diet and climate, as well as explanations as to why we look like we do. For example, the researchers believe that a major step was taken when we discovered the art of cooking, because then we didn't have to chew as much as before. For it was then that our faces began to shrink, a reduction which then took further momentum when we became sedentary and began to cultivate the earth."
"But, in addition, should the development of the modern human capacity for a non-verbal communication have played a crucial role in order to survive and reproduce in a larger group, say the researchers."
