All Change at Longleat
9pm, BBC1
In 2010, the Marquess of Bath, he of the “wifelets”, ceded control of the Longleat estate to his son, googly-eyed Ceawlin. How’s this gone? As Ceawlin, lately married to Emma, lets the cameras in for this three-parter, we get the chance to find out – as well as to be reminded that we can all, at surprisingly reasonable prices, visit the house and its lion-packed lands. Cynicism aside, there are revealing moments here as the series charts intergenerational tensions and disquiet over rent rises. Hugh Bonneville narrates. Jonathan Wright
Countdown To Life: The Extraordinary Making of You
9pm, BBC2
Michael Mosley presents this three-part look at how we all got here. Episode one focuses on the first eight weeks of life – that is, from when the foetus is formed in the womb and the tiny little heart makes its first beat. Amazing graphics accompany interviews with truly astonishing humans, each with a remarkable story to tell about how this early part of the process determined the rest of their lives. Another landmark BBC series reeking of quality and in-depth research. Julia Raeside
The Catch
9pm, Channel 4
“Welcome aboard the SS Starvation … ” In this episode of the eye-opening series, the crew of the Govenek are at breaking point in the face of appalling weather and damaged nets. “I’m like a dog that’s been bitten by everything on a hot day,” moans skipper Phil. Even his smartphone is asking him not to swear so much. There’s one chance of salvaging the nets, with a perilous iron hook called the Creep. But, we learn, “It’s a bit like Macbeth … nobody wants to mention the Creep!” Ali Catterall
Girls Can Code
9pm, BBC3
Part of the BBC’s Make It Digital initiative, this new talent show hosted by Radio 1’s Alice Levine challenges six women to discover the expert coders lurking beneath their “selfie queen” facades. Episode one sees contestants – including fashion graduate Tolani and art student Daisy – meet some of Britain’s most powerful female techies and work on a startup of their own. Interesting concept, but will putting the spotlight on these novices rather than their Silicon Roundabout counterparts make for inadvertently patronising fare? Hannah J Davies
Singing in the Rainforest
9pm, Watch
A new-five part series in which Scottish indie band Glasvegas and “classical musician” Myleene Klass leave their customary environs behind and travel to visit remote tribes from around the world as would-be musical emissaries. Klass visits the Ulithians on the Pacific island of Mog Mog, where she will create a desert island studio despite the lack of running water and electricity, while Glasvegas venture to the Amazon rainforest by canoe. The music they produce with their hosts will be available for download after the show. David Stubbs
6 Degrees of Separation
10pm, BBC2
Never mind television, if the premise of this new comedy panel show is to be believed, there’s nothing original in the entirety of the known universe. Six Degrees arrives armed with the proposition that even the most disparate of entities are actually closely linked. Such a concept carries an unabashedly cerebral remit, apparently insisting panellists possess at least a PhD before participating. That might explain the choice of professor Brian Cox as chair, as opposed to the more obvious choice of Kevin Bacon. Mark Gibbings-Jones
Mumbai High: The Musical
10pm, BBC4
A musical documentary, Mumbai High is a film that follows life at a school in Dharavi, the largest slum in Asia. For the teachers, the chief task has been imposing and then maintaining a sense of order amid this poverty and chaos. Cleanliness, a simple uniform, identity cards – the school creates a sense of belonging and then begins its educational mission. It won’t be everyone who can stay the course for an hour of songs, but the filming places you close enough to the ground for a flavour of this extraordinary place. John Robinson

Of Horses and Men (Benedikt Erlingsson, 2013) 12.30am, Film4
A curious, captivating film about the connections between horses and people, beautifully photographed in strange and magnificent Icelandic landscapes; there’s really not another film like it. The lives (and deaths) of various members of a quirky little horsebreeding community are examined, chief among them the tightly wound Kolbeinn, who rides his petite white mare to visit his love, the widow Solveig, owner of a black stallion.
