i would be making a comparison between political leaders and other types of primates, chimpanzee, baboons, moneys, so forth. but as i got into my work more and more, a number of questions began emerging that i could not answer. that puzzled me. for example, why was it that there were so few women rulers in the 20th century. brian: how many have there been? arnold: a total of 27 out of 1,941, the percentage was 1.4%. of those, half of them -- at least half were either wives of some famous politician, they borrowed their husband's charisma or daughters of him. and so that left, if you look at just women who have made it on their own, that was .75%. the chances of a woman becoming a ruler in the 20th century is over 100 to one odds against it. that puzzled me. the reason it puzzled me was there are have many very brilliant competent women. and surely many, many more should have been able to have maneuvered themselves into positions of power, despite a lot of social constraints and cultural constraints and that type of thing. so that was one thing. another thing that puzzled me, as i looked a

my colleagues in bristol are investigating the theft of two rhesus monkeys and a baboon, removed onlyt week. a traveling menagerie in oxfordshire have lost a prize chimpanzee, and matston their finest gorilla. >> big charlie? >> yes. >> delightful chap, i knew him well. >> well, they've all disappeared without a trace. >> and mr. holmes, what's his interest? >> he insisted to me that this may have relevance to another case he has in hand. we like to indulge him when we can, you know. find anything to the purpose, mr. holmes? >> nothing much. >> oh, i warned you. my men have been through it with a toothcomb. the lock was released by swell jenkins of stepney green. the primate was quietened and with a pad of chloroform administered by someone who lavishes their hair with mr. brewster of german street's pomade. this would suggest that he also sports a waxed mustache. mr. brewster being celebrated for his cosmetic wax for gentlemen. if this was so, lestrade, you could do worse than have a word with harry "the 'tache" wilcox of soho. >> good lord, holmes. your "nothing much" would be anyon

we eventually dip into the 115-degree heat, and after making sure there are no baboons or warthogs onunway, touch down in the national park. bob is there. good to meet you, bob. anxious to get us into the bush before sunset. and eager to tell of this place that's become one of the most audacious experiments in africa. >> here is a nice scene. these -- >> reporter: oh. >> the babies are everywhere. i mean, look, everything has a baby now. it's just -- it's nuts. >> reporter: he's spent most of his life like this. one hand on the wheel or camera, eyes peeled for movement. but this place has really honed his game-spotting skills because the wildlife here was almost wiped away entirely. 15 years of civil war made this the lost eden. while around 1 million people lost their lives, soldiers also shot almost every creature that moved. eat the meat or sell the ivory. for there was once tens of thousands of buffalo. after the war, they could find only 15. only five zebras. only six lions. and when bob arrived, he could find only one species that truly thrived. crocodiles. >> you see it's just

throw everything including the kitchen sink, the garage door opener, and two dozen pair of oversized baboon becoming the nominee. but i'm getting ahead of my myself." it's still a big unknown who will win in iowa and new hampshire, but ron paul is no stranger to getting pummeled by the republican establishment. >>> and finally, date night for the first lady. you'll be surprised to find out i'm not talking about with the president. late last week, first lady michelle obama was donating gifts at a military base in maryland when one of the cadets mustered up the courage to ask that she join him at next year's marine corps ball as his date. apparently the first lady said she'd love to go but had to speak with the president first. and the "will she or won't she" speculation made its way into the white house press briefing. >> the first lady had a marine corps toy for tots event today and a 20-year-old asked her to be his date at the marine corps ball next year. and he claims that she would love to do it, but had to check with her husband. has the president -- >> if the president's watching this,
