Small pet peeve of mine is how the language of "x group evolved towards y" makes it seem Lamarckian - like "they needed it, so they grew it". 

Even though we get taught genetic variability & natural selection at school, I have so many acquaintances that default or slip back into Lamarck when they should know better, and I genuinely think a big part of it is the language. 

Species don't "evolve X" in any such direct way!
