fake Posted December 29, 2011 Share Posted December 29, 2011 Although the left may control the right its the cerebellum that coordinates the fine motor control movements and not the main brain. Its now thought that right or left-handedness is down to genetics. http://www.scientificamerican.com/article.cfm?id=what-causes-some-people-t Link to comment Share on other sites More sharing options...
Frank Sidney Posted December 29, 2011 Share Posted December 29, 2011 I'm sure I once knew someone who was left footed but right handed. This proves that its not a side of the body thing, dunt it?... Link to comment Share on other sites More sharing options...
Hairyloon Posted December 30, 2011 Share Posted December 30, 2011 Sword use would be one skill where you would get a very important evolutionary advantage from being ambidextrous as they were absolutely a matter of life or death. No, there had been no significant evolutionary change to the species for a long long lime before swords came along. I expect you would find that monkeys are also right or left handed: if so, the root of the question goes much further back... I wonder how far.

Rupert_Baehr Posted December 30, 2011 Share Posted December 30, 2011 This link might amuse you. If the dancer appears to be turning clockwise, you are using the right side of your brain. If she's turning anti-clockwise, you're using the left. If the direction of rotation changes, you're switching between the two. Dual processing.

Cyclone Posted December 31, 2011 Share Posted December 31, 2011 Well that would be a nonsensical theory then as I think it's pretty well documented that the left side of the brain controls the right hand side of the body and visa versa. Next. No, that would fit in exactly with what he suggested. The left hemisphere is most often where we process language (70% of people I think), fine motor control seems to be associated with this language processing (in that the same side of the brain processes fine motor control in the majority of people). Being the left hand side of the brain, that explains why most people are right handed. Link to comment Share on other sites More sharing options...
Nagel Posted December 31, 2011 Author Share Posted December 31, 2011 This link might amuse you. If the dancer appears to be turning clockwise, you are using the right side of your brain. If she's turning anti-clockwise, you're using the left. If the direction of rotation changes, you're switching between the two. Dual processing. Clockwise for me and I can't even make her go anti-clockwise if I try. I'm not sure what that means Link to comment Share on other sites More sharing options...
sccsux Posted December 31, 2011 Share Posted December 31, 2011 It's all down to brain function. From one of the articles that have been linked to on here, it seems to be down to eyesight (which one of the two has the strongest visual range). Something I found interesting from one of the articles is that all sulphur crested cockatoos are left-footed. Link to comment Share on other sites More sharing options...

Rupert_Baehr Posted December 31, 2011 Share Posted December 31, 2011 ...Something I found interesting from one of the articles is that all sulphur crested cockatoos are left-footed. Apparently, all tabby cats are female. Most (but not all) ginger cats are male. (My brother had a ginger tomcat. He had it neutered and it had kittens.)
