Animal testing at the University of California, Los Angeles (UCLA) shut down the experiments in his lab after threats from animal rights activists. The researcher had received a grant to use 30 macaque monkeys for vision experiments; each monkey was anesthetized for a single physiological experiment lasting up to 120 hours, and then euthanized. The researcher's name, phone number, and address were posted on the website of the Primate Freedom Project. Demonstrations were held in front of his home. A Molotov cocktail was placed on the porch of what was believed to be the home of another UCLA primate researcher; instead, it
Arunachal macaque and 3500 m above sea level, making it one of the highest-dwelling primates. It belongs to the "M. sinica" species-group of macaques, along with the Assamese macaque ("M. assamensis"), the Tibetan macaque ("M. thibetana"), the bonnet macaque ("M. radiata") and the toque macaque ("M. sinica"). The Arunachal macaque is apparently physically similar to the Assam and Tibetan macaques, while genetically closely related to the bonnet macaque of southern India. This is probably the result of convergent evolution, where organisms evolve similar physical features due to similar environmental selection pressure, while genetically they may have different origins. However, its full specific
