how science is sometimes trumped by your mom

mom: (re: the terrier we're dogsitting): do you think she can tell us apart by looking at us?
me: dogs rely more on smells and sounds than visual cues i think.
me: and anyway, even if they could tell us apart by sight, they probably wouldn't be very good at it. animals' brains evolve so that they're specialised at distinguishing members of their own species but not others.
mom: that's not true. i can recognize all the lizards in the kitchen.

and...winner.

(this is a lot funnier if you know the history of my mom and lizards)
