What are your guesses about the origin of the chimeran virus?

My theory is that the Russians had some sort of Bio experiment going that went terribly wrong and infected thousands of beetles that crawled into people, thus turning them into chimera.

The one thing I would add to Coi Cki's theory is the possibility that there's perhaps a Chimeran Mother Ship telling them what to do, cause how else would they know they needed the towers? or, maybe the asteroid was actually a ship?

quote Coi Cki

Here's my theory:

The original Chimera were aliens. Their "cooling towers" caused the last ice age, but then the towers malfunctioned, and the temperatures began rising, causing the Chimera to flee to cooler areas of the planet, such as Siberia, maybe other locations, as well. They eventually died, and got buried, until 1908, when the meteor struck earth in Tunguska, Siberia. The team sent to investigate found the remains of the Chimera, and that marked the beginning of a long research project with the alien DNA, and experiments were made with animals, and probably convicted criminals as well. Thus, basing the ground for a hybridisation of humans and the Chimera.

Eventually, The Great War began, and the russian scientists had discovered a potential weapon in the Chimeran DNA, combined with some virus. The Cloven were created, at first, everything went well, but then, things began to go terribly wrong, and some of the cloven evolved into Chimera, and soon began their invasion, using technology from the towers, they eventually dug out of the ground. This led to the decision by the russian officials to call their soldiers back home to defend the motherland from the invasion, and to prevent it from spreading beyond their borders. The chimera spent the years inside the walls to gather humans for their army, and then they launched their attack on Europe.
