Interesting article on orcas - the only other animal to have a menopause. And why this might have evolved.

Jess, i heard a small part of this yesterday and find it fascinating, but i can honestly say i for one am so glad we humans are a part of this small elite group. How on earth (or in the sea!) do they cope without HRT ?

I listened to something similar on Radio 4. The interesting part for me was how dependent the adult males are on their mothers. When a granny Orca dies, the death rate among her 30 + year old sons soars, because she was still feeding them!
