"Hominid" takes place several million years ago in the Central African region between rainforest and savanna. The main characters are australopithecus afarenses, a hominid mostly living on trees that existed before the use of tools and fire. The story is told in the first person by the main character, Pitar. In thinking about his social and natural environment, Pitar decides to lead his family to civilization: "Hence I decided to shed some light on the darkness, to light a candle following the motto Let there be light and so on". His linguistic knowledge, thoughts and sayings are those of modern man, including a big knowledge about history, politics, philosophy and literature. Several comments made by Pitar about a particular object that has not been invented or developed yet, add to the funniness of the scenario. Pitar's close friends are Carpediem, who says Latin phrases and quotes the writers of Classical Antiquity, and Lao, who often refers to Chinese philosophy.
