Alien Life

This is huge!  thus says The Speculust.  A life form with a different DNA than all other life on earth.  The DNA of a newly discovered bacteria has arsenic instead of phosphorus.

If it's from this planet, is there some path by which it could have evolved from common ancestors of the rest of the biosphere? If so, how could that have happened? Every other living thing on earth shares the same chemistry -- but not these bacteria.

And if it's NOT from this planet...

Let's just say that raises some questios, too.

I agree with him.

The Washington Post talks about it here.
