And so I am on Chapter 7, which is about instinct and animals that do things for the exclusive good of others. A very noble concept to say the least.
Of course Darwin did many studies to back up his theories. One of these studies involved getting aphids to excrete a sweet juice that the ants like to feed on, without the ants present. He tried to get them to excrete said juice by tickling the aphids with a single hair. Talk about devotion to his project! I of course was cracking up as I read this paragraph. Alas, the aphid would only excrete the juice when the ant was present.
Woo almost halfway through!
