It's a good bet that if there were any advanced civilizations in our universe, they would have had to evolve in a similar way as we are doing.

I suspect that there may be oceans on these life Bering planets with sharks in the oceans, and Jurassic forms of life. - One reason is that the sharks we have on planet earth are very efficient on body design. - Once a species adapts to its environment, evolution stops.

In the case of the sharks, these animals stopped evolving before the dinosaurs walked on the earth.

So, it may be a good guess that if there were advance civilizations in our universe, there home planets would have oceans with sharks that look similar to ours. - Beyond that, life must take a similar path as on earth.

I often thought that advanced civilizations might be more like a "star wars" space bar where all sorts of animals evolved into higher thinking beings.
