Now here, on this unknown world, twenty-five million light years beyond the periphery of the Earth patrols—here we found men, men like ourselves!

Baiel cut the thongs and lifted the rigid body off the pile of rock. "If you don't mind, Captain," he said, "I'd like to examine—this—up in the ship lab. Since there's a chance—just a chance, sir"—His sarcasm was unmistakable, "—that we'll be staying here, I want to know what we're up against."

Late that night, while the rest of the expedition slept, Baiel and I carried the body into the laboratory. Baiel performed a thoroughgoing, workman-like autopsy. It was impossible not to admire his efficiency and skill. We were momentarily united in the rising excitement of mutual curiosity.

"There's a fascinating structural similarity to our own," Baiel pointed out. "Identical organs; identical blood composition. All the differences are minor—a smaller brain case, with a retreating forehead, and pronounced orbital ridges. And look at those teeth and the chinless jaw!"

"In a way, it suggests Bonn's Hypothesis," I said.

"Aubrey Bonn? Why, he's the laughing stock of the Anthropological Academy. We've never found a whisper of evidence to suggest a basis for his Hypothesis."

"How could we? There have never been any people on any of the planets we've explored."

Baiel dropped his scalpel and stepped back from the table, kneading his chin thoughtfully. "Bonn said that an identical chemistry and atmosphere, plus identical time phase, would produce an identical chronology of the species. This planet may do that. It should have been obvious when we had the negative tests for fissionable material. The Earth itself is the only planetary body we know where we've had to build separation plants to recover the metal."


"But, according to Bonn's Hypothesis, the resemblance should be exact." With disgust, I glanced at the torn corpse on the table. "None of us has an idiot's skull like that."
