The latest Attenborough series "First Life" screens on the ABC tonight (Sunday 27th Feb) at 7:30pm. It's a two part series about some of the earliest life forms.
I love any series presented by David Attenborough, but this one was a bit heavy going for a layman like me. Still, I will definitely check out the second part too.
His three part series on Madagascar has just been shown in the UK and is excellent. There is also a fourth programme about Aepyornis, which also features some fantastic scenes of him hand-feeding a wild indri.
