It is also a general consensus amongst biologists that the last common
ancestor was most likely a thermophile, since it is so deeply rooted
in the tree of life. Read the following for more detail: [URL snipped]

It is a fairly widespread belief, but I wouldn't call it a consensus.

One recent naysayer:

"Rooting the tree of life by transition analyses", Thomas Cavalier-Smith

http://www.biology-direct.com/content/1/1/19

That is a very nice paper (and like all Cavalier-Smith papers, very long and
very dense). I'm impressed by his reasoning, but a bit skeptical. I have
long believed that the LCA was a photoautotroph. But not an oxygenic one!
Cavalier-Smith's scheme makes being non-aerobic a derived secondary trait
which has been re-invented repeatedly in evolution. Well, maybe ...

Thx for the link, Tim.
