cows and stroked it gently at the base of the neck. It had been years since Peter had been this close to a cow; he’d grown up in Regina, but still had relatives who owned dairy farms elsewhere in Saskatchewan, and he’d spent parts of his boyhood summers there.
Like all cows, this one had enormous brown eyes and wet nostrils. It seemed unperturbed by Peter touching it, and so, without further ado, he gently strapped the modified scanning helmet onto its loaf-shaped head. The beast mooed at him, but more in apparent surprise than protest. Its breath stank.
“That it, Doc?” asked the foreperson.
Peter looked at the animal again. He felt a little sorry for it. “Yes.”
At this slaughterhouse, cattle were normally stunned with an electrical charge before being killed. But that method would overload Peter’s scanner. So instead this particular cow would be rendered unconscious with carbon dioxide gas, hung, and then have its throat slit for drainage. Peter had seen a lot of surgery over the years, but that cutting had always been to cure. He was surprised at how upsetting he found the killing of the animal. The foreperson invited him to stay for a full tour, including the butchering of a cow, but Peter didn’t have the stomach for it. He simply retrieved the special bovine headgear and his recording equipment, thanked the various people he’d inconvenienced, and headed back to his office.
Peter spent the rest of the day going over the recording, trying various computer-enhancement techniques on the data. The results were always the same. No matter what method he used or how hard he looked, he could find no evidence that cows had souls—nothing of any kind seemed to exit the brain at death. Not too surprising a revelation, he supposed, although he was quickly coming to realize that for every person who would hail him as a genius for his discoveries, there’d be another who’d damn him for them. In this case, the radical animal-rights lobby would surely be upset.
Peter and Cathy had been planning to go to Barberian’s, their favorite steakhouse, for dinner that night. At the last minute, though, Peter canceled their reservation and they went to a vegetarian restaurant instead.
WHEN PETER HOBSON had taken a university elective in taxonomy, the two species of chimpanzees had been Pan troglodytes (common chimps) and Pan paniscus (pygmy chimps).
But the split between chimps and humans had occurred just 500,000 generations ago, and they still have 98.4% of their DNA in common. In 1993, a group including evolutionist Richard Dawkins and bestselling science-fiction writer Douglas Adams published the Declaration on Great Apes, which urged the adoption of a bill of rights for our simian cousins.
In took thirteen years, but eventually their declaration came to be argued at the UN. An unprecedented resolution was adopted formally reclassifying chimpanzees as members of genus Homo, meaning there were now three extant species of humanity: Homo sapiens, Homo troglodytes, and Homo paniscus. Human rights were divided into two broad categories: those, such as the entitlement to life, liberty, and freedom from torture, that applied to all members of genus Homo, and other rights, such as pursuit of happiness, religious freedom, and ownership of land, that were reserved exclusively to H. sapiens.
Of course, under Homo rights, no one could ever kill a chimp again for experimental purposes—indeed, no one could imprison a chimp in a lab. And many nations had modified their legal definitions of homicide to include the killing of chimps.
Adriaan Kortlandt, the first animal behaviorist to observe wild chimpanzees, once referred to them as “eerie souls in animals’ furs.” But now Peter Hobson was in a position to see how literally Kortlandt’s observation should be taken. The soulwave existed in Homo sapiens. It did not exist in Bos taurus, the common cow. Peter supported the simian-rights movement, but all the good that had been done in the last few years might be undone if it were shown that humans had souls but chimps did not. Still, Peter knew that if he himself did not do the test, someone else eventually would.
Even though chimps were no longer captured for labs, zoos, or circuses, some were still living in human-operated facilities. The United Kingdom, Canada, the U.S., Tanzania, and Burundi jointly funded a chimpanzee retirement home in Glasgow—of all places—for chimps that couldn’t be returned to the wild. Peter phoned the sanctuary, to find out if any of the chimps there were near death. According to the director, Brenda MacTavish, several
