monkey business

22 Apr 2016

At http://archaeologynewsnetwork.blogspot.co.uk/2016/04/first-north-america... ... (see also www.smithsonianmag.com/smart-news/monkeys-may-have-floated-to-north-amer...) ... is one of those stories where a new find is like a torpedo, holing a consensus theory in the midriffs. Fossil teeth of monkeys have been unearthed by the Panama Canal expansion project. It was thought monkeys crossed over from South America when the two parts of the continent came together around 3.5 million years ago. Now we have fossils dating long before the consensus, at 21 million years ago. However, the authors come up with an explanation - monkeys reached the north as a result of rafting in on islands of vegetation and driftwood. Surely, the consensus theory is right, you might have heard them say - but it looks like their dating of the collision event between North and South America might be up the tubes.
