Did they say it wasn't caused by a glass of water either?

Sorry.

Interesting -

How can we be sure the chimp sample hasn't been contaminated with human
genes? This seems to be a great question with the pre-historic samples and
a problem for labs, even those who strive for contamination free samples and
work.

Have regulatory genes been separated or identified as different from
regular genes? In mice? In humans?
