Darwin wanted to know how plants colonised islands, so he did experiments with seeds to sea if they floated in salt water and if they would germinate after a week of such. He also tried feeding seeds to fish on the theory that they might be eaten by birds and the seeds then transported to new islands.

The amusing tale of how, whilst in the grip of beetle collecting mania, Darwin put one example between his teeth so he could grab another, only to have the first squirt acid down his throat...

 

The Voyage of the Beagle has several crazy tales of similar ilk about the life of a natural history student collecting specimens.

Darwin decries Lamark's views on the origin of species. I wonder what he would have thought about the current view that Lamarkian inheritance actually occurs in rare, limited circumstances? (Noone is claiming it is a dominant mechanism for speciation, mind.)
