That is an idea we are testing. Science News. Original written by Stuart Wolpert. That suggests the adaptive advantage of a unique mug evolved before modern humans did. To see whether our faces vary by chance or by natural selection, Sheehan and co-author Michael Nachman sifted through anatomical statistics from a U.

Faces allow for non-verbal social interaction, including recognition and . to the shape of the modern human face, but to interpret its evolution.

    The way we perceive faces -- using the right hemisphere of the brain -- is unique and sets There are unanswered questions about how faces evolve and what factors explain the evolution of facial features. The researchers even looked back at the DNA of a Neanderthal and a Denisovan, two extinct human species who showed a degree of facial variability similar to us.

    Santana, Lynch Alfaro and Alfaro present the first quantitative evidence linking social behavior to the evolution of facial diversity and complexity in primates, and they also show that ecology controls aspects of facial patterns.

    Santana also devised a way to test a theory that has been in the biological literature for decades but had never been tested before.

    So important that facial recognition is one of many innate reflexive cognitive competencies.
    The most variable traits are found within the triangle of the eyes, mouth and nose.

    They found that facial features are far more variable than other bodily traits, and that each facial feature varies independently from the others, which is unusual for most body measurements.

    Species that live in larger groups live in closer proximity to one another and tend to use facial expressions more than species in smaller groups that are more spread out.

    We're very visually oriented, and we get a lot of information from the face. Why are the faces of primates so dramatically different from one another? The findings do suggest, Alfaro said, that an important factor in shaping human faces is the premium on making unambiguous facial expressions.

    Being in closer proximity puts a stronger pressure on using facial expressions.

      They also used statistical methods to analyze the evolutionary history of the primate groups and when they diverged from one another.

    2. Kazrajora:

      In the future, Santana, Lynch Alfaro and Alfaro may use computer facial-recognition software to help quantify the faces in a more sophisticated way.

      Researchers studied 40 Hispanic infants and 37 non-Hispanic white infants, all 11 months old.

    5. Mak:

      The life scientists divided each face into 14 regions; coded the color of each part, including the hair and skin; studied the patterns and anatomy of the faces; and gave each a "facial complexity" score.
