Although BioArtists work with living matter, there is some debate as to the stages at which matter can be considered to be alive or living. Creating living beings and practicing in the life sciences brings about ethical, social, and aesthetic inquiry. The phrase "BioArt" was coined by Eduardo Kac in 1997 in relation to his artwork "Time Capsule". Although it originated at the end of the 20th century, through the works of pioneers like Suzanne Anker, Joe Davis, and the artists hosted by Symbiotica, BioArt is more widely practiced now.
