Thanks to Textcritic I've been slowly making my way through the EvolutionDocumentary channel on youtube

I'm not sure if it's the accent, or my recent obsession with British TV, but I find BBC and Channel 4 programs to be much more engaging and with higher production values.
I found a really interesting one about dogs yesterday, all about domestication and how they have evolved for life along side of us. I found particularly interesting a couple of experiments attempting to domesticate wolves and foxes.
