The Kennewick Man Finally Freed to Share His Secrets - Day 4

Day four. You can learn more about Doug Owsley at Wikipedia.

The most poignant outcome? The researchers brought Kennewick Man’s features back to life. This process is nothing like the computerized restoration seen in the television show Bones. To turn a skull into a face is a time-consuming, handcrafted procedure, a marriage of science and art. Skeletal anatomists, modelmakers, forensic and figurative sculptors, a photographic researcher and a painter toiled many months to do it.

The first stage involved plotting dozens of points on a cast of the skull and marking the depth of tissue at those points. (Forensic anatomists had collected tissue-depth data over the years, first by pushing pins into the faces of cadavers, and later by using ultrasound and CT scans.) With the points gridded out, a forensic sculptor layered clay on the skull to the proper depths.

The naked clay head was then taken to StudioEIS in Brooklyn, which specializes in reconstructions for museums. There, sculptors aged his face, adding wrinkles and a touch of weathering, and put in the scar from the forehead injury. Using historic photographs of Ainu and Polynesians as a reference, they sculpted the fine, soft-tissue details of the lips, nose and eyes, and gave him a facial expression—a resolute, purposeful gaze consistent with his osteobiography as a hunter, fisherman and long-distance traveler. They added a beard like those commonly found among the Ainu. As for skin tone, a warm brown was chosen, to account for his natural color deepened by the harsh effects of a life lived outdoors. To prevent too much artistic license from creeping into the reconstruction, every stage of the work was reviewed and critiqued by physical anthropologists.

“I look at him every day,” Owsley said to me. “I’ve spent ten years with this man trying to better understand him. He’s an ambassador from that ancient time period. And man, did he have a story.”

Today, the bones remain in storage at the Burke Museum, and the tribes continue to believe that Kennewick Man is their ancestor. They want the remains back for reburial. The corps, which still controls the skeleton, denied Owsley’s request to conduct numerous tests, including a histological examination of thin, stained sections of bone to help fix Kennewick Man’s age. Chemical analyses on a lone tooth would enable the scientists to narrow the search for his homeland by identifying what he ate and drank as a child. A tooth would also be a good source of DNA. Biomolecular science is advancing so rapidly that within five to ten years it may be possible to know what diseases Kennewick Man suffered from and what caused his death.

Today’s scientists still have questions for this skeleton, and future scientists will no doubt have new ones. Kennewick Man has more to tell.
