Last year 2650 people attended the clambake, and, because there seemed to be a "psychological barrier" to going outside and eating, many had to wait while the first arrivals ate their lobster or roast beef dinners, Koivumaki said...
...other in the arm. Commandeering an Opel at gunpoint from a passing motorist, he and his companion sped off in the direction of the highway to Stuttgart.

In the same vein, retired Columbia Biochemist Erwin Chargaff asks: "Have we the right to counteract, irreversibly, the evolutionary wisdom of millions of years in order to satisfy the ambition and the curiosity of a few scientists...

The accomplishment seemed to breach one of nature's more inviolable barriers. Even primates as closely related as gorilla and man are so different genetically that they cannot produce offspring. Thus it was not size alone that made King Kong and his ladylove a mismatch. The real species barrier is in the genes...
