Mike Walsh interviews beloved broadcaster and naturalist David Attenborough about his television series and book, Life on Earth. When Walsh says that the amount of time that's condensed into the series is incomprehensible Attenborough says 'if you take the time from the beginning of life as we know it from fossils to now and call that a year, then one day is ten million years. Fish don't appear until some time in October and man appears about quarter past 12 on December 31st.' Attenborough says he was interested in animals as a child, as all children are, and that he just never grew out of it.

Episode 0080 of The Mike Walsh Show was broadcast on 2 June 1980.
