 Do not belittle eyebrows! It may be an important factor for human survival.


Note: what is the use of the eyebrows? (Figure / Eduardo Munoz Alvarez) Your first year teacher might explain that eyebrows can prevent dust from entering the eyes. But is the answer complete? Is there any other reason? A new study, published recently in the journal Nature: Ecology and evolution, gives a new explanation: eyebrows are an important symbol of our communication. It is the eyebrows that make us an evolutionary advantage! Our closest ancestral ancestors, neandertha, and the brow of Danny, are very prominent, while the brow of the Homo sapiens is more smooth and smooth. In contrast, the brow of the Homo sapiens should be small and high in position. In this way, Homo sapiens can move eyebrows for subtle communication. The reader can make up the picture of the color dance. The expression conveyed by the eyebrows is usually more friendly information and less attacking information. Researchers say that eyebrow communication helps Homo sapiens establish a larger social network, which enables Homo sapiens to gain the upper hand in survival games. Note: the left side is the skull of a modern man and the skull of Rhodes West is on the right. It is clear that the latters brow is more prominent.

Paul OHiggins, an anatomy professor at York University, is responsible for leading the research project. OHiggins and his colleagues used 3D software to simulate the skull of ancient primitive Heidelberg people. Heidelberg people appeared on the earth about 600 thousand to 200 thousand years ago. The fossil bones borrowed from the study are from the British Museum of natural history, which is also famous for the fossils of Rhodes. Many experts today believe that the Rhodes people found in Africa are also part of the Heidelberg people. The researchers built a computerized model of cranium fossils and studied their brow. Dr. Ricardo Godinho also participated in the study. He interpreted the results of the study in a press release. We simulated the bite strength of different positions of teeth, and we found that the force of biting force to the brow ridge was very small. Then we removed the brow of the skull model and found that it had no effect on other parts of the face. Godinho said. The test is simple, but significant, because the two main theories are excluded: the first theory is that the prominent brow can stabilize the skull; the second theory is that the space between the eye socket and the skull needs to be filled with prominent brow ridges. Two theories of biology have been excluded, and the remaining theory is brow ridge is a form of social interaction. Especially in other species, males will use this feature to show their advantages and to overcome potential competitors in mating season. Readers can also make up the picture of dancing with flying colors. For example, consider deer antlers and think about how they fight with their competitors with antlers. Over the past 100 thousand years, especially over the past 20 thousand years, our way of life has shifted from hunting to farming, and our faces are not only less threatening, but smaller and softer. Note: the Heidelberg man model. (picture / Smithson Museum of natural history of the United States) Dr. Penny Spikins, an archaeologist, CO authored the paper. All the other primitive human species were extinct. Only we survived and prospered. Dr Penny believes that our rise is due to excellent interpersonal interaction. Social interaction helps us better connect and form a larger social network. The social network here is obviously not the social network built by Zuckerberg. Eyebrows move, which enables us to express more complex emotions. Similarly, we can perceive other peoples emotions through eyebrows. The role of eyebrows can also be carried out in cross culture, such as the approval and opening of social interaction can be seen through eyebrows, such as eyebrow movements can also express compassion. Penny said in a press release. Penny continued, by observing the tiny movements of the eyebrows, it helps to see if others are telling the truth. Studies also show that browning movements restricted by Botox are limited, and their ability to understand other eyebrow messages is also poor. Compared with other extinct Terran families, our modern peoples social life has been helped by eyebrows. The nandanda people are very able to run and have a strong athletic ability. But do you think the Neanderthal people are extinct due to the lack of eyebrows? Do you have any idea about the extinction of the Neanderthal people?
