## size can be hindering

Probably every body can think of one situation or another where this statement is in order and even if it comes to our brains one easily finds moments where a big brain is debilitating.
And finally there is evidence that this is part of a bigger evolutionary picture: scientists recently found out in a simulation why our brains have shrunk. One systematical flaw – especially for a simulation designed to run over several thousand generations of humans – is that they neglected females in their model (too complicated!). (Still this analysis could explain our poor performance against the martians…)
