I notice that the above-mentioned article about the dig in Kenya found fish
bones among the fauna apparently processed with stone tools at the site.

If I'm not mistaken, this may be the earliest evidence of fish consumption
by humans to date.  Although the fish bones were less than 1% of the fauna
remains found at the site, they were clearly there, along with other
aquatic animals.  (see

It was said that when people heard Cicero speak they said, "What a clever
fellow is Cicero," but when they heard Demosthenes speak they said, "Let us
march against Philip."
