Zombies in Nature - seriously

It's true: nature gives us example after example of insects and animals which have essentially become zombies - whose central nervous system has been taken over by any number of parasites.

These videos of snails, bullet ants, aphids, caterpillars, cockroaches - among other creatures - all show that parasites completely overrun the host creatures brain to create a perfect living environment, even making the host creature (which it is slowly killing) defend the parasite from external threats!

While this is shocking, the phenomenon does not stop with lower life forms ... even humans are believed to be susceptible to parasitic take over. Through a parasite known as toxoplasma gondii (commonly found in cat waste), humans are believed to suffer from schizophrenia.
