a pacemaker that initiated each contraction of a heart beat

"Autorhythmic cells: cardiac or smooth muscle fibers that are self-excitable; act as the heart's pacemaker and conduct the pacing impulse through the conduction system of the heart; self-excitable neurons in central nervous system,as in the inspiratory area of the brain stem." -Principles of Anotomy and physiology, TORTORA, DERRICKSON, 11th edition, Wiley & sons, Inc.

Who invented dancing?

No individual invented dance, as music and movement date from the earliest modern humans.The significance of dance is related to language, custom, and ritual, and any sort of regular rhythmic sound seems to trigger a sympathetic activity in the human brain and body. Dance may have developed concurrently with sign language as a form of communication.According to an article in Scientific American in 2008, "dance is a fundamental form of human expression that is intertwined with language and music. It is viewed as a marriage of the representational capacity of language and the rhythmicity of music, allowing people to tell stories with their bodies while synchronizing their bodies."Dancing is an ancient art form that cannot be credited to one inventor. The earliest civilizations used dance for rituals and as a form of communication.
