Threw out the decades of being domesticated the cows behaviour changed
This is because they have been around humans for so long that they are use to being around us.
The cows were not as aggressive towards humans as the were decades ago they are more docile and gentle
After several decades of the new species of cow being protected by the humans they did not have any need for their horns which is now a vestigial organ.
The cows vestigial organ is slowly disapearing becuase they do not need it any more and now 99.9% of the population does not have horns
That has been the evolution of the cow, hope u learned something bye.
