But in general, most researchers — including Stringer and McPherron — think that the bulk of any cultural exchange passed the other way, from humans to Neanderthals. All traces of Neanderthals disappeared by about 40,000 years ago. A team of archaeologists has found evidence to suggest that Neanderthals were the first to produce a type of specialised bone tool, still used in some modern cultures today.

When it was discovered in 1856 in Germany, scientists had never seen a specimen like it: An astronomer's view of aliens What do you do with the world's most powerful laser? Shipman, P. The entire dataset of participant and flake measurements used in the study can be found in the S1 Dataset File.
Neanderthals used tools for activities like hunting and sewing.
The human superiority in vocal production may therefore be explained by uniquely sophisticated neural control rather than special vocal anatomy. From action to language: Tools, language and cognition in human evolution.
Since the 335 flakes were produced by 71 participants, the four measures of skill were calculated viable flakes, proportion of viable flakes or averaged flake cutting edge, total quality for each subject. Often a tool was percussion flaked to start with and then followed up with pressure flaking. The speech group also performed significantly worse than the full language group in all four measures, and as poorly as the control group receiving no instruction no significant differences in any of the four measures.
Significance levels: Participants instructed through speech showed mean and median satisfaction scores below the mid-point of 3 on the 1-to-5 scale, with the exception of Question 3 with median at the mid-point Table 1. Ohnuma and colleagues [ 16 ] focused on the experimental production of Levallois flakes Mode 3 characteristic of the African Middle Stone Age and the European Middle Palaeolithic.
