We rarely come across research that leads to true connections with human evolution in other animals, but menopause is an almost unique event that has deep meaning for survival. With these whales, we have a link to one of our own particular characteristics that can only be investigated in these species. Who knows what information we may find among orca ecotypes and even other unique species.
When the politics of greenhouse gases finally unravel, it wont be our children who come to conclusions about it. It will be more distant descendants who acclaim our restriction of CFCs, but what can they say about the current mess? We need climate champions, and they are rare in some politics. Lets hope they can read (the writing on the wall) at least! Here it is, using a new EMIC simulation that provides accuracy, evidence and good conclusions.
Whether we want to find rare populations of crickets, bats or whales, acoustic signs are worth recording. Instead of sometimes-impossible genetic ID, call signs give often-deeper analysis of how populations differ in so-called cultures. In the case of this blue whale study, new discoveries are inevitable as the long-lived, long-generation and simply just long animal recovers from hunting that could easily have occurred within their lifetime!
When dolphins are 'rescued' in various countries, the car given seems to be ill-considered. We are simply looking at the success rate which is reported to be low, in most places. They could even end up in commercial aquarium shows, but they certainly rarely make it back to the sea.
