We know almost nothing about when M253 occurred, other than it happened more than 4500 years ago but less than 20,000 or so years ago. See "Tree for I1" at http://knordtvedt.home.bresnan.net You can see I estimate the time range for L338 to be between 2000 years ago and 3200 years ago. MRCA for I1-AS1 was about 2000 years ago. I believe the location was NW Germany for the L338+, but I have not seen another clade of haplogroup I as strongly present in Netherlands as AS1. -----Original Message----- From: J E DESTEIGUER Sent: Tuesday, January 03, 2012 4:05 PM To: Y-DNA-HAPLOGROUP-I@rootsweb.com Subject: [yDNAhgI] Occurrence of L338? I recently tested positive for L338. I am curious: do we know about when this mutation appeared, especially relative to M253? And am I correct in saying it likely appeared first in north Germany or the Netherlands? Thanks and Happy New Year.
