At last the 2012 Yearbook is ready. With a bit of luck and a fair wind it will be on sale to the general public within the next week or so at £12.50 plus postage. However, here is a special offer for all of you loyal readers of the CFZ Bloggo Network.
Pre-order now and get it at the discount price of £10.99 postage free. I am afraid that this offer is only good for readers in the UK or USA. However, if you are somewhere else and still want to buy the book in advance email me on jon@eclipse.co.uk or Corinna on corinna@cfz.org.uk and we will do you the best deal that we can...
As regular readers of the CFZ Bloggo network will be aware. Jeanett Thomas (48) has been missing for over a month. Her husband, our old friend Lars Thomas, has been on Danish TV, and the story has been on the front page of the biggest Danish newspapers.
Appeals for information have proliferated across the Internet and the cryptozoological community has rallied around. All we can do is repeat that:
Lars asks: "Please, if you know, or have heard anything, let me know."
Contact Lars: lars_thomas@msn.com
Or me: jon@eclipse.co.uk
Our thoughts and prayers are with Lars and his two sons at this terrible time.
This blasted recession is really beginning to hit. Unlike some of our competitors we are not going to try and blackmail you into donating by saying that we won't continue if you don't. That would just be vulgar, but our lives, and those of the animals which we look after, would be a damn sight easier if we receive more donations to our fighting fund. Donate via Paypal today...
Richard Freeman's remarkable new book is now available. However, for some reason known only to themselves amazon.co.uk have listed it as taking 3-5 weeks to arrive.
In November Sahar Dimus, our guide on four CFZ Sumatra expeditions, died of liver failure leaving a widow Lucy and four Children. On the 2nd November, Dezyama D. Sangma, wife of our friend and colleague Dipu Marak, our collaborator on the 2010 Indian expedition died, leaving her grieving husband and two small children.

It's really an amazing find.
The introduction of common blacktip genes might "pollute" the Australian blacktip's gene pool, but that might not be the best way to think about it.
The discovery that modern humans mated with Neanderthals and Denisovans has led to a possibility that we might have inherited some beneficial traits from these species.
There is some evidence that some of our MHC (Major Histocompatibility Complex genes came from Neanderthals and Denisovans. MHC genes control our immune response. New MHC genes could mean that would would have become more resistant to disease, thereby allowing us to colonize Eurasia, Australia, and North America more effectively:

Although this study has been attackd, the possibility that some of our superiority as a species may have come through hybridization should lead us to question whether hybridization in wild species is always a bad thing.
Species that can hybridize sometimes do in the wild-- like wolves and coyotes and Canada lynx and bobcats. And these hybrids can be more fit.
Of course, it doesn't always work this way. You can get hybrids that do have health and fertility issues-- not always the result of Haldane's rule. Campbell's and winter white dwarf hamster often are bred together in captivity, and real health problems do result.
But one should not assume gloom and doom when a hybrid pops up.
In this case, the Australian blacktip might be able to colonize other parts of Australia besides the northern regions.
