Tool Use Discoveries in Anthropology

Scientific articles about tool use as an indicator of pre-human activity in the distant past may have to be rewritten. New discoveries show that the “tools” some anthropologists claimed were used by ancient hominids may be stone flakes accidentally created by monkeys.

Researchers have observed long-tailed macaques in Thailand using rocks to pound open palm nuts. When they use rocks containing flint or quartz, they create flakes or shards. Those fragments are very similar to some sharp-edge stone fragments researchers previously thought were created by ancient humans in East Africa.

Scientists have used what they call intentionally produced sharp-edged stones as proof of the evolutionary development of emerging humans. They used the “flake technology” to infer the degree of cognitive ability, including knowing how to select the types of rocks to give specific properties for making tools. Despite this “new” research, experienced field workers had previously observed monkeys inadvertently producing stone flakes and sometimes even using them as grooming tools.

Today’s anthropologists have moved beyond tool use to determine whether a specimen was human. They can sometimes use DNA found in the remains of the individuals. DNA studies have led to the understanding that all humans are related and that the gene pool has been thoroughly mixed over the ages.

The biblical reference is very simple. The name “Eve” means the mother of all living humans (Genesis 3:20). “Adam” means “of the ground,” referring to the fact that our physical bodies consist of elements found in the earth. “In the sweat of your face shall you eat bread until you return to the ground, for out of it you were taken. For dust you are, and to dust you shall return” (Genesis 3:19).

What sets humans apart is not tool use but our spiritual makeup. All humans are made in the image of God. We are all one physically, and the Bible calls us to become one spiritually. (See Galatians 3:28 and Ephesians 2:14.)

Human-Macaque Chimera Created

Human-Macaque Chimera and Ancient Greek Mythology

A chimera is a living organism made up of parts from different organisms. You have heard myths about a half-woman, half-fish mermaid, and a human torso and head on a horse’s body and legs. Those would be chimeras if they actually existed. Now scientists have created a human-macaque chimera.

Scientists at the Salk Institute in California injected human stem cells into macaque embryos. They allowed the embryos to grow for only 20 days before destroying them. The stated purpose for creating a human-macaque chimera is to find a way to grow human organs for transplant and to develop new drugs.

This reminds us of a science fiction story of chimeras turning into monsters that threaten human beings. The term “chimera” (kye-MER-uh) comes from an animal in Greek mythology with a lion’s head and body, a goat’s head protruding from its back, and a tail with the head of a snake. Imagine what a human-macaque chimera might be like.

This experiment raises bioethical questions. Just because researchers can do this, should they do it, and what kind of research should they carry on? Insoo Hyun, a bioethicist involved in this research, says that chimeras have “the potential to radically humanize the biology of laboratory animals.”

The morals and beliefs of the scientists doing the research become a significant issue in situations like this. We need people with Christian values involved in making these decisions to ensure that everything is done to relieve human pain and suffering, not to create half-human creatures. God has provided the blueprint in DNA, but it is up to humans to decide how to use it. Whether it is for good or evil is an old biblical question.

Tool Use Is Not What Makes Humans Unique

Tool Use Is Not What Makes Humans Unique 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.

Cloned Monkeys — Humans Next?

Reuters.com reports that the Chinese Academy of Sciences has solved the technical problems of cloning higher life forms. Mu-ming Poo announced that two long-tailed macaques named Hua Hua and Zhong Zhong were produced using somatic cell nuclear transfer in which transferred DNA was taken from fetal monkey cells and put into cells from which they had removed the DNA. By stimulating these eggs, they developed into embryos which were implanted in female surrogates and two live births of cloned monkeys resulted.

The question of cloning has many dimensions to it. Cloning can be used to solve many problems. An article in The Week (February 16, 2018) says that this process could “revolutionize research on diseases including cancer, Alzheimer’s and Parkinson’s.” The potential to address food shortages could lie within cloning of unusually large plants and animals or food stocks with special characteristics such as protein content, resistance to pests, etc. Cloning could also be used destructively to produce diseases or science fiction products like human androids.

The question remains whether scientists will clone humans. Since scientists at the University of Edinburgh in Scotland cloned “Dolly” the sheep in 1996, others have cloned 22 mammal species including cows, dogs, horses, and rabbits. Now the Chinese researchers have broken the primate barrier with cloned monkeys.

In cloning the macaques, 127 eggs resulted in 79 embryos which led to only six pregnancies and two live births. The ethics of such an inefficient process with humans raises a whole new set of abortion questions and Frankenstein type scientific, moral issues. Scientists will address the physical issues with future improvements in techniques, but someone must address the moral issues before they attempt human cloning.

The Bible defines a human as a being created in the image of God. A cloned human would be as human as one produced by artificial insemination or surrogacy or by the old-fashioned method. What we CAN DO and what we SHOULD DO are not necessarily the same. We need people with Christian moral values making the decisions on what we should do.
