The Return of the Tasmanian Tiger ... sort of ...

According to this article, scientists have discovered a way to insert DNA from the now-extinct Tasmanian tiger, or thylacine, into a mouse embryo. While it is not yet possible to restore extinct species to life, this is an important step in that direction. This is a key reason why I support genetic engineering: when used responsibly, it can help us to repair some of the damage that humanity has done to Earth's biosphere. Let's not throw out the patch kit right when we need it most, okay?

Not all extinctions are natural. Most animals do not selectively kill one or a few species without the intent to eat the entire thing. For example, killing an elephant just for the ivory in its trunks, killing alligators and snakes only for the skin, killing rabbits only for their feet, and killing many foxes, moose, deer and others for sport.

Humans have forced extinctions which would not have happened otherwise. On the other hand, we "saved" a species that *was* going extinct through natural selection (the whooping crane).

Homo sapiens consistently takes more than it requires. This is the root cause of most (if not all) the major issues with which we find ourselves contending on a global scale.

Have you got any references for the Whooping Crane extinction being natural? All I've heard on that front have been human factors, first DDT (the usual eggshell problem) and later -- more seriously -- habitat destruction. If there are natural factors that got crowded out, I'd be interested in expanding my data acquisition in that direction.

Not directly since it was something I was taught in 2nd year bio at university. :/
