Input: Hand axes mark an evolutionary advance in human history -- tools fashioned to function as what Darwinians call "fitness signals" -- that is to say, displays that are performances like the peacock's tail, except that, unlike hair and feathers, the hand axes are consciously cleverly crafted.
Output:
Ručne sjekire su obilježene kao evolutivni napredak u ljudskoj povijesti -- alati oblikovani za slanje kao što bi ih pristaše Darwina nazvali signala sposobnosti -- to jest, pokazuju da su predstave poput paunovog repa, pored svega, za razliku od dlake i perja, ručne sjekire su svjesno pametno oblikovane.
