"Charlie has human cusp patterns on all his teeth.

"Many of our adaptations are far from perfect. The arrangement of internal organs leaves much to be desired, owing to our inheriting a system originally developed to suit a horizontal and not an upright posture. In our respiratory system, for example, we find that the wastes and dirt that accumulate in the throat and nasal regions drain inside and not outside, as happened originally, a prime cause of many bronchial and chest complaints not suffered by four-footed animals. That's hardly perfection, is it?"

Danchekker took a sip of water and made an appealing gesture to the room in general.

"So, we see that any idea of convergence toward the ideal is not supported by the facts. Charlie exhibits all our faults and imperfections as well as our improvements. No, I'm sorry—I appreciate that these questions are voiced in the best tradition of leaving no possibility unprobed and I commend you for them, but really, we must dismiss them."

Silence enveloped the room at his concluding words. On all sides, everybody seemed to be staring thoughtfully through the table, through the walls, or through the ceiling.

Caldwell placed his hands on the table and looked around until satisfied that nobody had anything to add.

"Looks like evolution stays put for a while longer," he grunted. "Thank you Professor."

Danchekker nodded without looking up.

"However," Caldwell continued, "the object of these meetings is to give everyone a chance to talk freely as well as listen. So far, some people haven't had much to say—especially one or two of the newcomers." Hunt realized with a start that Caldwell was looking straight at him. "Our English visitor, for example, whom most of you already know. Dr. Hunt, do you have any views that we ought to hear about . . . ?"

Next to Caldwell, Lyn Garland was making no attempt to conceal a wide smile. Hunt took a long draw at his cigarette and used the delay to collect his thoughts. In the time it took for him to coolly emit one long, diffuse cloud of smoke and flick his hand at the ashtray, all the pieces clicked together in his brain with the smooth precision of the binary regiments parading through the registers of the computers downstairs. Lyn's persistent cross-examinations, her visits to the Ocean, his presence here—Caldwell had found a catalyst.

Hunt surveyed the array of attentive faces. "Most of what's been said reasserts the accepted principles of comparative anatomy and evolutionary theory. Just to clear the record for anyone with misleading ideas, I've no intention of questioning them. However, the conclusion could be summed up by saying that since Charlie comes from the same ancestors as we do, he must have evolved on Earth the same as we did."

"That is so," threw in Danchekker.
