Out of Eden

A Sunday school teacher asked her students to draw a picture of their favorite Old Testament story. As she moved around the class, she saw there were many wonderful drawings being done. Then she came across the drawing of one little boy. He was busy drawing a man driving an old car. In the backseat were two passengers—both scantily dressed.”
"It's a lovely picture,” prompted the teacher, “but which story does it tell?”
The little boy seemed surprised at the question. “Well,” he exclaimed, “doesn't it say in the Bible that God drove Adam and Eve out of the Garden of Eden?”

Louis Laurent Gabriel de Mortillet

Died 25 Sep 1898 at age 77 (born 29 Aug 1821).French anthropologist who was the first to organize man's prehistoric cultural developments into a sequence of epochs. Based on the idea that older specimens of man were more primitive structurally and culturally, he created a ladder-like model of the evolution of man. This model was the basis for the idea of linear evolution of men. This classification system was further detailed in 1882, in Le Prehistorique: antiquite de l'homme (The Prehistoric: Man's Antiquity). His classification system continued to be the basis for anthropological classification into the 1900's. For example, he ordered the Paleolithic (Stone Age) epochs into Chellean, Acheulian, Mousterian, Solutrean, Magdalenian, and so on.
