Alroy's computer model predicted the extinction or survival of 32 of 41 Clovis prey species. He concluded, long before the dawn of written history, human impacts were responsible for a fantastically destructive wave of extinctions around the globe. Southeast of present-day Tucson, along the Santa Cruz River, there are three famous Clovis sites.

You suspect in long-ago Clovis lore this may have been a legendary event. Or, given that many similar stories follow it in the historical record of America, maybe what transpired here wasn't legendary at all, just the way things were done. What seems to have happened is that at the most westerly location, now called the Lenner site, a Clovis band surrounded a family group of 15 mammoths.

The herd apparently huddled together for defense against the assault. But 13 of them, all adolescents and calves, died in the spot. Archaeologists found exactly 13 Clovis points in their remains. But it must not have been an easy thing. In different locations a few miles away, the Escapul and Naco sites, archaeologists found two adult mammoths who had apparently fled the slaughter.

The large male had died with two Clovis points in his body, but the female must have put up a tremendous fight to protect her young before mortally wounded, she had fled. and her remains, there were no fewer than eight embedded Clovis points. The hunters who killed those mammoths appear to have been absolute professionals.

Our best strategy for understanding America's Pleistocene extinctions may be on an animal-by-animal basis. Clovis hunters almost certainly wiped out the elephants and Folsom people the giant bison. But animals like dire wolves, giant beavers, and big cats may have simply been out-competed by gray wolves and modern beavers and cougars.

Smaller size and earlier sexual maturity fitted the replacements better for an America now inhabited by human predators, the first examples on the continent for what biologists called anthropogenic evolution. Horses and camels do remain enigmas.

Sites of Clovis Age in southern Alberta and Colorado show horse and camel kills, but nothing like the vast number of horses from solutrean sites in Europe. And why did various camelids survive in South America, providing later native people domestic possibilities, but not farther north? As for the Clovisians themselves, they remain maddeningly elusive.
