Behavioral biology is really interesting with a variety of survival strategies that are exhibited by both animals, and humans. Our understanding about behavioral biology is astounding, although it is yet to be completed.

We can now explain various social behaviors in terms of genes. Topics like sociobiology, sociogenomics, chronobiology, and biomimicry have achieved significant success within a very short period of time.

Human behavioral study is also steadily advancing. Studies on human behavior can explain why we are so careful for our sons, or daughters. The beauty of human behavioral studies lies in our communication ability through language, unique facial structure, and facial symmetry, and even in the attractiveness of voice.

Development of language along with an increase in brain size are important contributors in the evolutionary history of mankind.

Behavior is known to be influenced by genes, the nervous and endocrine systems, and the environment. New disciplines are coming out using the knowledge of behavioral biology. Now let us consider the attractiveness of voice in humans.

A recent (2004) study published in the journal, Evolution and Human Behavior (Vol. 25, pp.295-304; doi:10.1016 /j.evol.hum.behav.2004.06.001)) states that the voice of a person may convey important information about his/her socioeconomic status, personality traits, age, height, and weight.

Individuals with symmetrical morphological traits have more attractive voices. Deviation from bilateral symmetry decrease rating of voice attractiveness.

Estrogen and progesterone shape the mature female’s voice. Testosterone shapes the male voice. These hormones are also associated with male/female body configuration features. Individuals with attractive voices are perceived more favorably and generally have a more desirable personality.
