The youtani Cows and the murlasi Cows

Once upon a time there were two species of cows. The Youtani and the Murlasi at first they liked each other but they found out that they were rivals at many things first at food then at strength then at speed and skill. At times one was better but at times the other was better they all liked hay and tomato juice whenever it was running out they would attack one another. The bad thing was that in the end unless the cow was a special one they would both end up bruised and tired then they would get hurt both had scientists but both had a exactly the same mind and thought of something new the same time except they called it different. They both tried harder at the same time. It was like for each and every Youtani cow there was and almost exactly the same Murlasi cow. So in the end they mixed up the species into Youlasi cows if you were Murlasi or Youtani you were Youlasi and later they were the best cow species. However they discovered new Cow species Evoulasi cows and it seemed they were also equal.
