To supplement last week’s discussion on language evolution, I stumbled upon an Indo-European language tree posted on Jonathan Beaton’s blog. Neither Jonathan nor do not know where it was published, nor what data was used to construct the tree and its relationships. So it may not be completely accurate… but it is a nifty illustration. Just cause I’m curious on how accurate the tree is, I’ve compared to Ethnologue’s report on Indo-European languages. The general trend on language relationships are accurate but many languages are left out.
