Can killer whales help solve the mystery of menopause?
« on: August 10, 2016, 08:50:07 AM »

Just seen this article on the BBC website - might be interseting.

Scientists from Exeter and York University are studying the evolution of the menopause, and have found clues to its origin in killer whales.
Humans and orca are two of only three species that evolved to stop having babies half-way through their lives - something even great apes and long-lived elephants do not do. While some have suggested that menopause is a side-effect of our own greater longevity, researchers say that orcas could hold the key to what's been a long-standing evolutionary mystery.
BBC science reporter Victoria Gill joined the scientists on an unusual whale-watching trip of the North Pacific Coast.
Filmed and edited by David Cheeseman and Victoria Gill

Yes I saw it! They have studied a pod/families in the wild for 40years ,the conclusion they have come to is that its essential for the older females to nnot be able to reproduce anymore so they can hunt thus leaving the younger mothers to fully look after the offspring !

Im off now to forage ........ :rofl:

Maybe it's the whales' hot flushes that are melting the polar ice caps   ;D
Seriously though, must listen to it

How very interesting! And yeah, CLKD - I wonder if they do get VA?!?

I really think I should be allowed to go out and hunt folk down too - I've got quite a list, and it's growing a lot lately...... :o

I heard it on the news at work today & they said 'two marine species', but didn't mention what the other one was. But they specifically said that apes and elephants can breed up to the end of their lives.

Hello ladies.

The lunchtime news  reported that the scientists had been closely following the whales from their boat.  If I was  a menopausal Orca they'd do well keep their distance!

Take care all.

 ;D ;D ;D

Maybe they don't get symptoms so badly - all that sea water must help cool down hot flushes!

Well then. Now we can guess why whales sometimes beach themselves! They're menopausal and trying to escape for a bit of fresh air.
