More "Parasites Rule"

It's Friday afternoon, so I thought a little parasite distraction might be in order. Over at Mental Floss, there's a nice list of eight different parasites that affect their hosts' behavior, in order to promote their transmission: zombie snails, crabs, caterpillars, grasshoppers, fish, ants, and cockroaches. Good creepy stuff for cocktail party or coffee shop evolutionary chit-chat for sure! The last sentence is a question about whether or not there are parasites that affect human behavior. Clearly these folks need to read up on Toxoplasma!
