Hello, Erik Springelkamp, and welcome to Wikipedia! I have reverted edits you made to Bow (weapon) and History of archery, because they seemed to be based on original research rather than the referenced source. Your comments may be correct, but we need to make sure that they are based on reliable sources in order to use them in Wikipedia. Thank you for your contributions. I hope that you enjoy editing Wikipedia and become a regular contributor. Richard Keatinge (talk) 16:14, 16 November 2009 (UTC)


 * Hello Richard.


 * My edit was probably not well formulated.


 * However, the source for that ancient arrowhead is more careful than the formulation in the Wikipedia text:


 * 

A slender point is consistent with a pin or needle-like implement, while a larger point, reminiscent of the single specimen from Peers Cave, parallels large un-poisoned bone arrow points from LSA, Iron Age and historical Bushman sites. Additional support for the Sibudu point having served as an arrow tip comes from backed lithics in the HP compatible with this use, and the recovery of older, larger bone and lithic points from Blombos Cave, interpreted as spear heads. If the bone point from the HP layers at Sibudu Cave is substantiated by future discoveries, this will push back the origin of bow and bone arrow technology by at least 20,000 years, and corroborate arguments in favour of the hypothesis that crucial technological innovations took place during the MSA in Africa.


 * I find "has been identified as arrowhead" much stronger than the original claim, so I think the text should be adapted a bit.


 * Also, the link to the Discovery page should be changed to the link to the original paper.

 * Erik, thanks for the very helpful reference. I now agree with your point and hope that we can produce a suitably-careful form of words. Further discussion on this should perhaps be in Talk:History of archery. Richard Keatinge (talk) 17:19, 16 November 2009 (UTC)

Hello Erik. I noted this edit you made to Gunter's Chain. Fascinating. Is there an English translation of that information? Moriori (talk) 20:59, 14 May 2014 (UTC)
