http://story.news.yahoo.com/news?tmpl=story&cid=573&ncid=757&e=4&u=/nm/20050415/od_nm/safrica_chimp_dcCharlie, a grown male chimp and the Bloemfontein Zoo, has been picking up cigarettes thrown to him by visitors and smoking them -- a habit he probably picked up by observing humans, zoo officials told the SAPA news agency on Thursday.
"Baby chimps pick up habits by mimicking adults and we think he started mimicking smokers at his enclosure which probably led to smokers throwing him cigarettes," spokesman Daryl Barnes told SAPA.
"He even acts like a naughty schoolboy by hiding the cigarette when staff approach the area," Barnes said, adding that the zoo was determined to help him quit.
Barnes said Charlie was already showing the signs of a true nicotine addict. I think this means one more point for the theory of evolution. :P
