Stone tools helped shape human hands
- forgottenpaswrd 14y agoI hate it so much when the only pictures you find on a web article are about advertising . More so when it is supposed to be about science.
- jonsen 14y agoIt would be interesting to know if people born with more than ten fingers are better typists.
- futhey 14y agoI was thinking if the trend is toward automation and away from physical labor some unique features could be selected for in 200,000 years or so.
- futhey 14y agoInteresting, but the active voice is rather misleading in the headline. The argument seems to actually say the expected: Humans who used stone tools were selected based on their tool use -> humans more suited for stone tool use continued to be selected -> stronger hands & wrists. I guess it serves some purpose to find specimens which verify the expected. Perhaps some less obvious insight will come of this.
- richardwhiuk 14y agoThat's fairly common in New Scientist headlines - see http://en.wikipedia.org/wiki/New_Scientist http://en.wikipedia.org/wiki/New_Scientist - in particular section 1.2.
- Evbn 14y agoWell, we could have, say, evolved a hand shape optimized for carrying our young, despite suboptimal tool weilding. But we didn't (according to this research anyway). So the headline correctly states the claim of the research.
- Retric 14y agoInteresting, however as an alternative hypothesis wrist strength is also vary important when using most hand held weapons especially a basic ax. From an evolutionary perspective making tools is probably less limited by wrist strength vs using them.
