normal skull, with a rounded protrusion at the back, almost like a hair bun. The doubly arched browridge was prominent and the forehead low. The nasal cavity was gigantic, with strange triangular projections pointing into it from either side. The huge mandible, visible at the bottom of the frame, revealed what the beard had hidden: the complete lack of a chin. It also showed a gap between the last molar and the rest of the jaw.
“I’ve never seen anything like it,” said Reuben.
Singh’s brown eyes were wide. “I have,” he said. “I have.” He turned to look at the man, who was still sitting in the wheelchair, babbling gibberish. Then Singh consulted the ghostly gray images again. “It is impossible,” said the Sikh. “Impossible.”
“What?”
“It cannot be …”
“What? Dr. Singh, for God’s sake—”
Singh raised his hand. “I do not know how it can be thus, but …”
“Yes? Yes?”
“This patient of yours,” said Singh, in a voice full of wonder, “appears to be a Neanderthal.”
Chapter 6
“Good night, Professor Vaughan.”
“Good night, Daria. See you tomorrow.” Mary Vaughan glanced at the clock; it was now 8:55 P.M. “Be careful.”
The young grad student smiled. “I will.” And she headed out of the lab.
Mary watched her go, remembering wistfully when her own figure had been as slim as Daria’s. Mary was thirty-eight, childless, and long separated from her husband.
She went back to poring over the autoradiograph film, reading off nucleotide after nucleotide. The DNA she was studying had been recovered from a passenger pigeon mounted at the Field Museum of Natural History; it had been sent here, to York University, to see whether it could be completely sequenced. Previous attempts had been made, but the DNA had always been too degraded. But Mary’s lab had had unprecedented success reconstructing DNA that other facilities couldn’t read.
Sadly, though, the sequence broke down; there was no way to determine from this sample what string of nucleotides had originally been present. Mary rubbed the bridge of her nose. She would have to extract some more DNA from the pigeon specimen, but she was too tired to do that tonight. She looked at the wall clock; it was now 9:25.
That wasn’t too late; many of the university’s summer evening classes got out at 9:00, so there should still be lots of people milling about. If she worked past 10:00 P.M., she usually called for someone from the campus walking service to escort her to her car. But, well, it didn’t really seem necessary this early in the evening. Mary removed her pale green lab coat and hung it on the rack by the door. It was August; the lab was air conditioned, but it was surely still quite warm out. Another sticky, uncomfortable night lay ahead.
Mary shut off the lights in the lab; one of the fluorescents strobed a bit as it died. She then locked the door and made her way down the second-floor corridor, past the Pepsi machine (Pepsi had paid York University two million dollars to become the exclusive soft-drink vendor on campus).
The corridor was lined with the usual bulletin boards, announcing faculty openings, classroom assignments, club meetings, come-ons for cheap credit cards and magazine subscriptions, and all sorts of items for sale by students and faculty, including one poor clown hoping to get someone to pay him money for an old electric typewriter.
Mary continued down the corridor, her heels clicking against the tiles. No one else was in the hallway. She did hear the sound of the urinals flushing as she passed the men’s room, but that happened automatically, governed by a timer.
The door to the stairwell had safety-glass windows, with wire mesh embedded in them. Mary pushed open the door and headed down the four flights of concrete steps, each flight taking her a half story lower. On the ground floor she left the stairwell and continued a short distance down another corridor, this one also empty except
