> "We haven't yet found a specific neural structure for recognizing faces" is far from evidence that no such structure exists.

proving a negative is, famously, quite hard. an unsolved problem, even. facial recognition has a plethora of evidence beyond an argument from evolution. the notion that we humanize tools is one that, as yet, lacks that evidence. I urge people to be more skeptical of arguments from evolution. we understand very little about our evolution and it's easy to insert our own worldviews and beliefs into such arguments, allowing them to state virtually anything we like in a plausible envelope with the shape of a scientific argument. I'm not just calling the argument about humanizing tools pseudoscience -- I'm applying it equally to every other argument from evolution that lacks other motivating evidence.
