The Yangtze river dolphin is officially declared extinct.
This is BBC’s take on it.
This extinction represents the disappearance of a complete branch of the evolutionary tree of life and emphasises that we have yet to take full responsibility in our role as guardians of the planet.
And this is Channel 4 ‘s article.
It is the first official extinction of a large vertebrate for more than 50 years.
UPDATE 29. August 2007: Not so dead after all apparently. This by Zooillogix and this according to the BBC.
