It wasn’t until after he lifted the skull out of the water that Thomas realized his jest wasn’t factually incorrect.
The duo tucked the cranium on dry land and moseyed over to the race. Afterward, they flagged a police officer, handing off the head in the bottom of a 5-gallon bucket. The skull and a few other bones then passed from the sheriff’s office to the coroner to a local forensic anthropologist, James Chatters, until someone carbon dated a finger and realized the remains were about 9,000 years old — making them among the oldest remains in North America.
The Kennewick Man, nine millennia after his death, was born.
Thomas and Deacy believed they had found a victim of murder or suicide. They had, in fact, found a victim — but the assault occurred long before Egyptians got around to building the pyramids. Chatters scoured the site on the Columbia River, finding an almost complete skeleton in freshly-eroded mud. While he was alive, the Kennewick Man had had a rough existence: One arm was withered, as though crushed, and he had been stabbed in the hip with a rock spear with the serrated tip embedding itself in his pelvic bone. It’s believed he survived the initial attack but not the infection.
Once the U.S. Army Corps of Engineers, which had control over the Columbia River property, caught wind of the bones’ ancient age, the agency demanded the remains. A local tribe, the Umatilla, had claimed the Kennewick Man as an ancestor; the Native American group wanted to lay the skeleton to rest according to custom. Chatters, who had teamed up with paleoanthropologists like the Smithsonian Institute’s renowned bone expert Douglas Owsley, resisted.
Thus began a debate that would last for 20 years. In one corner were the scientists, who over the years have wanted to sequence the Kennewick Man’s DNA and scrape his molars to see what he ate. Burial without first letting scientists analyze the bones, paleontologist Thomas Stafford told the Denver Post in 1997, “would be like burning the great library of Alexandria.”
In the other corner was a coalition of five Native American groups — the Nez Perce, Yakama, Wanapum and Colville tribes, along with the Umatilla, who refer to the Kennewick Man as the Ancient One. Their legal footing, they say, is the Native American Graves Protection and Repatriation Act — legislation enacted in 1990 as a way to return cultural items kept by federal agencies and museum collections.
By September of 1996, the Army Corps of Engineers had possession of the remains — minus a few thigh bones, which mysteriously vanished in the process. (Years later, the Federal Bureau of Investigation would hunt for the bones and launch an investigation when the body parts resurfaced in the Kennewick sheriff’s evidence vault.) In response, Owsley and seven other scientists, wanting to examine the bones, sued the Corps in federal court.
“We believe that something this ancient is a precious gift,” Alan Schneider, an attorney for the paleontologists, told Newsday at the time. “If we repatriate it we should gather as much information as possible for future generations.” Meanwhile, the Kennewick Man surfaced from the mud only to be sealed in a safe at the Pacific Northwest National Laboratory, beyond the reach of camera lenses and analytical equipment.
Umatilla religious leader Armand Minthorn was unimpressed with the researchers’ entreaty. “Some scientists say that if this individual is not studied further, we, as Indians, will be destroying evidence of our own history,” he said in a statement on behalf of his tribe as the debate raged on. “We already know our history. It is passed on to us through our elders and through our religious practices.”
The legal battle wove its way through the federal court system — at an estimated cost of at least $5 million in taxpayer money — until 2004, when a San Francisco federal appeals court ruled in favor of the scientists: There was not enough evidence that the Kennewick Man belonged to one of the tribes, and, therefore, the Native American Graves Protection and Repatriation Act was not relevant. Chatters and the other anthropologists successfully argued the skull morphology was closer to those of the Ainu, an ancient Japanese tribe, than the cranial features of Native Americans.
But a sliver of hope remained for the five tribes. According to the Seattle Times, the appeals court wrote that if data surfaces indicating the Kennewick Man “may be Native American, it might cause us to reopen the analysis.”
In the meantime, Owsley had the liberty to move forward with his research. As the Smithsonian Magazine reported:
A vast amount of data was collected in the 16 days Owsley and colleagues spent with the bones. Twenty-two scientists scrutinized the almost 300 bones and fragments. Led by Kari Bruwelheide, a forensic anthropologist at the Smithsonian, they first reassembled the fragile skeleton so they could see it as a whole. They built a shallow box, added a layer of fine sand, and covered that with black velvet; then Bruwelheide laid out the skeleton, bone by bone, shaping the sand underneath to cradle each piece. Now the researchers could address such questions as Kennewick Man’s age, height, weight, body build, general health and fitness, and injuries. They could also tell whether he was deliberately buried, and if so, the position of his body in the grave.Next the skeleton was taken apart, and certain key bones studied intensively. The limb bones and ribs were CT-scanned at the University of Washington Medical Center. These scans used far more radiation than would be safe for living tissue, and as a result they produced detailed, three-dimensional images that allowed the bones to be digitally sliced up any which way. With additional CT scans, the team members built resin models of the skull and other important bones. They made a replica from a scan of the spearpoint in the hip.As work progressed, a portrait of Kennewick Man emerged. He does not belong to any living human population.
But Owsley and the Smithsonian team weren’t the only scientists who wanted in on the Kennewick Man’s dance card. An international team of geneticists, led by researchers at Stanford University and the University of Copenhagen, extracted biologic information from 200 milligrams of Kennewick Man hand bone. And the results that they published, in the journal Nature in 2015, flew in the face of Owsley’s morphologic work. “Using ancient DNA, we were able to show that Kennewick Man is more closely related to Native Americans than any other population,” said Morten Rasmussen, a Stanford geneticist and author of the research, in a statement.
This was just the sort of evidence that could fly through the window the appeals court had left open. A year after the Nature announcement, a team at the University of Chicago confirmed that the Kennewick Man is genetically related to Native Americans in the Pacific Northwest. And, on Wednesday, the Army Corps of Engineers — which is in possession of the remains — declared that it’s working with the Native American tribes to coordinate a burial.
The tribes responded positively to the news of the Kennewick Man’s return. But a representative for the Confederated Tribes of the Umatilla told the Associated Press that the scientific evidence “acknowledges what we already knew and have been saying” for the past 20 years. As the Umatilla leader Minthorn said in 1996: “If this individual is truly over 9,000 years old, that only substantiates our belief that he is Native American. From our oral histories, we know that our people have been part of this land since the beginning of time.”
