How does something that 'just jumped species' infect more readily than our most infectious endemic disease, the flu, STRAIGHT OUT OF THE DOOR? If this were really naturally evolved it would have needed some time after the species jump to pick up its new fancy mutations. Instead, what we see is like a 5 year old orphan that picks up a violin for the very first time and starts playing Beethovens Sonata no 9. This shit came out of a lab.
