When I took my first anthropology course at Indiana University in 1958, the professors said that humans are the only animals that fashion and use tools. Later, scientists discovered that chimpanzees could smash rocks until they get one that has a sharp edge. Then they use that sharp edge as a tool to cut open fruit or dig for ants. Louis Leakey, the anthropology guru of that time, stated, “We are either going to have to change our definition of man, or invite the chimps to send a representative to the United Nations.” Tool use is not what makes humans unique.
Since that time, other animals have been observed using tools and some even manufacturing tools. Nuthatches can find a stick that they can slide under the bark of a tree to get at a bug. Crows can fashion a stick and use it to get into a milk bottle. The picture shows a macaque using a stone to smash a crab shell for food. Science now says that less than one percent of all animals use tools, but that number keeps growing. Discover Magazine for November 2019 (page 22), contained an article about skunks picking up a rock and pounding on the ice in a pond to make a hole for drinking.
The Bible does not identify humans according to tool use or any technological accomplishment. Mentally challenged humans might not make tools or use them, but they are still humans, no matter what their abilities. What defines humans is our spiritual makeup, which the Bible describes as being in the image of God. This image gives us the capacity to express ourselves in worship, in artistic expression, and in the ability to feel guilt and be sympathetic. Tool use is just one of many designed characteristics built into the DNA of many forms of life. But tool use is not what makes humans unique.
