3 But this happens when innate sensors detect intense chewing pressures and internal workings interpret that stress and then activate jaw bone and muscle growth during childhood development. Even today, human faces look different when we eat raw and unprocessed food. In other words, our ancestors’ facial traits supposedly changed at least partly in response to what they ate. And that’s just the facial differences.Ĭompletely unfazed by the fact that no scientist has seen natural selection craft a single such feature-let alone something akin to the entire suite listed here-ASU News wrote, “Changes in the jaw, teeth and face responded to shifts in diet and feeding behavior.” 1 Good luck restructuring all that biology with nothing but a series of random mutations. Apes’ closed mouths hide that soft red tissue that human lips have on constant display. The distance between teeth and cheekbones is shorter in humans than in primates. Only human eyes have the whites showing in such a way that we can communicate merely using eye motions. Look close-chimps have no hairy eyebrows. Even men with thick beards have smooth skin in spaces where apes have furry faces. 2 Their combinations of contractions craft a cornucopia of communication. Humans have about 20 more facial muscles than modern chimpanzees. Here are a few face features that Darwinists need natural selection and mutations to somehow expertly craft in just a few million years: This may sound like no big deal until one begins to list the many differences. The team needed to imagine how natural processes could have transformed a chimpanzee-like face into a human’s. 1 Their science-sounding terms masked a failure to face certain facts that should have framed their conclusion. How did our marvelous faces get here?Ī team based at Arizona State University (ASU) Institute of Human Origins recently speculated on how the distinct features of human faces evolved from ape-like faces. Each person’s face does all this while looking unique among billions of others. They also keep sun and dust out of those sensors, and they enable us to breathe, eat, speak, and sing. They hold sensors for sight, smell, sound, temperature, and humidity. Hundreds of different tiny facial expressions can convey our thoughts and feelings in an instant-all using the human face. Parr will present this new data at the upcoming "Mind of the Chimpanzee" conference, an international multidisciplinary conference on chimpanzee cognition being held March 22-25 at the Lincoln Park Zoo in Chicago.Animals don’t laugh, smirk, roll their eyes, or give subtle squints like humans do. This is how we determined when the chimpanzees were using a single feature or if they needed more than one feature to match the similar expressions," said Sheila Sterk, a senior animal behavior management specialist on Parr's team. The chimpanzees then were asked to match the new expression to the original one. "After the chimpanzees matched similar images, we separated individual features of the original animated expression, such as a raised brow, by frame and pieced the frames back together to create a variation of the original expression. Using Chimp FACS, the chimpanzees in the study observed anatomically correct 3D animations of chimpanzee facial expressions and then were asked to match the similar ones. To facilitate her studies, Parr developed the Chimpanzee Facial Action Coding System (Chimp FACS) to directly compare documented expressions of humans and chimpanzees. Ultimately, we want to better understand what people are feeling and expressing emotionally because it helps us empathize with one another," Parr continued. "Sometimes it's easy to read what people are feeling, but at other times, we have to look at multiple places on their faces. This is similar to what researchers see in human emotional expressions. While some expressions, such as a playful look, can be identified using a single feature, other expressions, such as when a chimp bares his teeth, require looking at numerous characteristics within the face, including the eyes and lips." According to Parr, "This discovery is an important step to help researchers recognize facial movements and understand why they are important.
