darwin's tumor

Ive read that cancer can be pretty clever - securing nutrition by releasing hormones which cause the creation of blood vessels, employing various methods of fooling our immune system etc. All these seem (at least to my layman's mind) to be pretty specialized eh... 'behaviors' i guess is the word. My question is, how would they evolve? [more inside]

A Rose By Any Other Name

its my understanding that stuff generally feels smells tastes or looks good because it benefits our survival. Fats and sugars have energy. Sex continues the species. Good interior design makes you feel safe - etc etc.

So why do flowers 'smell good'?
