-I recently watched Marc Forster's World War Z (2013) starring Brad Pitt, Mireille Enos, and Daniella Kertesz. The IMDb link is here: http://www.imdb.com/title/tt0816711/?ref_=nv_sr_1

-This movie follows a man during the brink of total world collapse as a zombie pandemic attacks the entire world. He goes across the entire world trying to find a cure. He ends up injecting himself with a deadly pathogen, which keeps the zombies from attacking him since they only go for a healthy host. Although slightly far-fetched, this movie was very entertaining. I enjoyed the scene where he injects himself with the serum and walks face to face with the zombie and essentially walks through the entire facility unscathed. He uses a soda machine to bring all the zombies to him and walks right through them. Entertaining movie. 7/10

-Now for the evolutionary side of this movie. The movie faces the traditional "can zombies happen?" question. This movie has zombies that have un-human-like strength and speed. There is no way for a person to come back from the dead, however, like in the case of rabies, it could be transmitted to another host. This is very interesting to me and I did some research. So the zombies in the movie are attacking others so the virus will have another host. There exists a parasite called Toxoplasma gondii that infects mice and has to be inside cats to reproduce. It works by making mice not afraid of cats so they will be eaten and therefore be able to reproduce. However, this is a parasite and a virus could be less likely to have this effect in humans. The zombies themselves are very intelligent. They are able to discern who is infected and who is not infected. That is very difficult for even a doctor who is not infected to discern. This would mean that the virus somehow gave them a special ability which is just not possible. The incubation time of the virus, (which is in the ballpark of 10 seconds in the movie) is unrealistic. Hold onto your pants, zombies won't be invading the world. Hopefully.
