This film explores why it pays to work as a team as it reveals some of the most captivating and awe-inspiring group parenting stories from the animal world. For most group-living species, living together means dividing the labour. From elephants taking part in hostage negotiations for their babies to banded mongoose all giving birth on the same day, female lions forming a sisterhood to see off interloping males and musk oxen rallying together to defend their calves from hungry wolves... it's truly amazing what some animal parents are prepared to do for the next generation!

And, in the ruins of the oldest temple on Earth, he tells the extraordinary story of how grass triggered human civilisation.
