Evolution... Interesting name. Guess you missed that bus! Unless the thread was a joke, of course.
No need to worry about the apocalypse guys 
, 9 out of 10 diseases are really overstated in their threat to human health (ex: H1N1: regular seasonal influenza has historically killed a few hundred-thousand people per year and about 50,000 a year in the US. About 60-75 million Americans are thought to have contracted H1N1 to date and of those, about 12,000 have died, which is actually a rather low death-rate...the media made it seem like if you got swine flu, you were a dead duck. The only odd thing about H1N1 is that the deaths are very evenly distributed in the population, and it seems to kill almost as many younger, healthy persons as it does older persons and young children, which is somewhat unusual.)
This is what you are referring to:

It is a theory that rabies will mutate to having an incubation period much like that of influenza/ILIs, or that other types of diseases that cause significant cognitive impairment and even aggressive behavior will 'change', and affect a large portion of the population in a very short amount of time. Theoretically, it could happen, but probably not with rabies, and thanks to public health, it is likely to create a 'Dawn of the Dead' scenario. Certain diseases are much more likely to mutate than others though; influenza is probably the best known example. A major reason for this is that our actions have affected the diseases themselves and prompted them to 'mutate'. It is also believed that certain man-made/synthetic viruses are more likely to mutate than non engineered viruses, but this is hard to say as determining what diseases are and are not produced by man is very difficult, and what constitutes a 'man-made' disease varies depending on who is defining it. An example is that cancer is believed by many to be a man-made disease. Now, you can view this in 2 different ways: 1) someone produced/created it in a lab, or 2) actions such as environment destruction, smoking, health choices (all which we directly affect) also makes cancer function differently. You could also say that antibiotic-resistance is a human creation as well.
Rabies in humans CAN produce violent behavior and involuntary motor movement, as can at least a few other diseases. It is also worth noting that immediate and proper rabies treatment with the rabies vaccine (and a few other drugs) is 100% effective in preventing death. Without the above treatment, the death rate is at least 95% (probably more like 99.5%), and only a handful of people have survived rabies in recent history. Because effective prevention exists as does a high death rate without the standard treatment, this decreases the chances of a zombie revolution. Human to human transmission of rabies is rare (in very few cases, it has happened however), and animal control departments have effective protocol for vaccinating certain animals prone to catching and spreading rabies, as well as safely destroying animals with rabies.

In the zombie flicks 28 Days Later and I Am Legend, an unstoppable viral plague sweeps across humanity, transforming people into mindless monsters with cannibalistic tendencies.
Though dead humans can't come back to life, certain viruses can induce such aggressive, zombie-like behavior, scientists say in the new National Geographic Channel documentary The Truth Behind Zombies, premiering Saturday at 10 p.m. ET/PT. (National Geographic News is part of the National Geographic Society, which part-owns the National Geographic Channel.)
For instance, rabiesa viral disease that infects the central nervous systemcan drive people to be violently mad, according to Samita Andreansky, a virologist at the University of Miami's Miller School of Medicine in Florida who also appears in the documentary.
Combine rabies with the ability of a flu virus to spread quickly through the air, and you might have the makings of a zombie apocalypse.
Rabies Virus Mutation Possible?
Unlike movie zombies, which become reanimated almost immediately after infection, the first signs a human has rabiessuch as anxiety, confusion, hallucinations, and paralysisdon't typically appear for ten days to a year, as the virus incubates inside the body.
Once rabies sets in, though, it's fatal within a week if left untreated.
If the genetic code of the rabies virus experienced enough changes, or mutations, its incubation time could be reduced dramatically, scientists say.
Many viruses have naturally high mutation rates and constantly change as a means of evading or bypassing the defenses of their hosts.
There are various ways viral mutations can occur, for example through copying mistakes during gene replication or damage from ultraviolet light.
(Related: "New, Fast-Evolving Rabies Virus Foundand Spreading.")
"If a rabies virus can mutate fast enough, it could cause infection within an hour or a few hours. That's entirely plausible," Andreansky said.
Airborne Rabies Would Create "Rage Virus"
But for the rabies virus to trigger a zombie pandemic like in the movies, it would also have to be much more contagious.
Humans typically catch rabies after being bitten by an infected animal, usually a dogand the infection usually stops there.
Thanks to pet vaccinations, people rarely contract rabies in the United States today, and even fewer people die from the disease. For example, in 2008 only two cases of human rabies infection were reported to the U.S. Centers for Disease Control and Prevention.
(See pictures of infectious animals in National Geographic magazine.)
A faster mode of transmission would be through the air, which is how the influenza virus spreads.
"All rabies has to do is go airborne, and you have the rage virus" like in 28 Days Later, Max Mogk, head of the Zombie Research Society, says in the documentary. The international nonprofit is devoted to "raising the level of zombie scholarship in the Arts and Sciences," according to their website.
To be transmitted by air, rabies would have to "borrow" traits from another virus, such as influenza.
Different forms, or strains, of the same virus can swap pieces of genetic code through processes called reassortment or recombination, said Elankumaran Subbiah, a virologist at Virginia Tech who was not involved in the documentary.
But unrelated viruses simply do not hybridize in nature, Subbiah told National Geographic News.
Likewise, it's scientifically unheard of for two radically different viruses such as rabies and influenza to borrow traits, he said.
"They're too different. They cannot share genetic information. Viruses assemble only parts that belong to them, and they don't mix and match from different families."
(Take a quiz on infectious diseases.)
Engineered Zombie Virus Possible?
It's theoretically possiblethough extremely difficultto create a hybrid rabies-influenza virus using modern genetic-engineering techniques, the University of Miami's Andreansky said.
"Sure, I could imagine a scenario where you mix rabies with a flu virus to get airborne transmission, a measles virus to get personality changes, the encephalitis virus to cook your brain with fever"and thus increase aggression even further"and throw in the ebola virus to cause you to bleed from your guts. Combine all these things, and you'll [get] something like a zombie virus," she said.
"But [nature] doesn't allow all of these things to happen at the same time. ... You'd most likely get a dead virus."
