The Biological Evolution of Music

     We enjoy listening to music as we like to observe attractive mates. These artists are attractive because they are able to both create music and improve their fertility.

     On an evolutionary aspect, the females who could detect (enjoy the music/be impressed) that the music artist is fertile would produce more babies. Music is basically a strong fertility agent that is used by humans as a sign of attractiveness.

     Not only is the ability to play music showing that you're fertile, it also shows that everything is good and you are not having problems with resources or danger (since your sitting around not concerned about those things).

Biological Reason
     Sperm have mu and delta opioid receptors. Playing music has been proven to release opioids such as beta endorphin in the body.

     The chemical release of beta endophin and other opioids increase sperm motility by activating these receptors. Sperm motility is the highest factor in male fertility. Infertile men have been found to have reduced levels of beta endorphin.

     Dopamine receptors release steroids and neurotransmitters. These chemicals are sexual stimulators. Listening to music has been shown to release dopamine. A heightened arousal will cause more babies to be produced.

History
     The first instruments ever made were flutes almost 35,000 years ago. Ancient flutes are often found in archaeological digs. They were made of simple material that they came in contact with all the time and were probably accidently invented.

     Listening to these instruments is like seeing a colorful image. Back in these times, humans were only exposed to so many sounds and colors. The way the human brain works is that receiving new material or stimuli releases happy neurotransmitters. The brain only dislikes music when it sees it as a threat or danger. These early instruments such as the flute and drum, evolved into more complex instruments such as the lyre and full blown orchestra.
