Macho B is a jaguar that lived and died in Arizona.
Although jaguars are native to Arizona, little is known about the population segment that resides in Mexico and uses southern Arizona and New Mexico as the northern extent of its range. It was thought the species had been extirpated from the state until 1996 when the first jaguar documented since 1986 was photographed by a southern Arizona rancher/mountain lion hunter. After capture, collar and release, a web of intrigue surrounded death of the only jaguar in Arizona, Macho B.
Excerpt
It all began at dusk one evening, under an outcropping of rock along the border between the US and Mexico, a male jaguar (Panthera onca) rose from his sleep, stretched, and silently but determinedly left the place he called home. A mysterious visitor from across the border, coming in the dark of night, a jaguar, dubbed by wildlife officials as Macho B, entered Cochise County, Arizona (Figure 1). Of course, he didn’t realize he’d crossed a border, animals aren’t aware of our human imposed boundaries. Upon arrival, Macho B found the territory available, except for Macho A, a young jaguar, also perhaps, looking for a new home.

Our human genome is full of viruses similar to HIV-1. These have played an important role in human evolution and still play an important role in human embryology and day-to-day chemistry. Just how important are they to our evolution past and future?
