Do Fruit Flies Have Emotions?

[Hatshepsut]

I think allowing the indiscriminate killing of, say, orangutans would be inconsistent with our ideas about human rights.  But it's pretty clear that there's a sliding scale of how we treat organisms: roughly, it's something like primates>monkeys>intelligent or cute mammals....

That "charismatic megafauna" thing. I seem to remember a sliding scale that went Caucasoid > Mongoloid > Negroid....used to justify racism 90 years ago. Although orangutans are in trouble; there may only be a few thousand left & pity if 7 billion of us can't make room for them.

Meanwhile, I was expecting a mutant fly array to turn up soon...
