Graph 1 (top): Each snake's BovB compared to cow BovB. Colored = match. Black = cow changed it.
Graph 2 (bottom): At positions the cow changed — do snakes still recognize the original (Vipera consensus)?
Finding: 97.4% of "cow-changed" regions are still recognized between snakes. The cow didn't create new code — it swapped one snake variant for another. Only 47bp (2.6%) are truly new.

Row per snake · Each pixel = 1bp · Colored = snake recognizes this position · Black = cow changed

Graph 2: Do snakes still share the "changed" regions?

Same positions · Blue = snakes match Vipera consensus here (cow changed but snakes still agree) · Red = truly new (nobody has this)
