when was the bow and arrow first invented
Bow and arrow The earliest definite remains of bow and arrow are from Europe. Possible fragments from Germany were found at Mannheim-Vogelstang dated 17,500-18,000 years ago, and at Stellmoor dated 11,000 years ago. Azilian points found in Grotte du Bichon, Switzerland, alongside the remains of both a bear and a hunter, with flint fragments found in the bear's third vertebra, suggest the use of arrows at 13,500 years ago.[7] At the site of Nataruk in Turkana County, Kenya, obsidian bladelets found embedded in a skull and within the thoracic cavity of another skeleton, suggest the use of stone-tipped arrows as weapons about 10,000 years ago.[8] Microliths discovered on the south coast of Africa suggest that projectile weapons of some sort may be at least 71,000 years old.[9]
Interchangeable parts In East Asia during the Warring States period and later the Qin Dynasty, bronze crossbow triggers and locking mechanisms were mass-produced and made to be interchangeable.
