Plate Tectonics and Possibilities

Recent observations have indicated that both Mars and the Moon may be more tectonically and geologically active than we thought.

This is a good indicator that planets in general may be more geologically active than we thought. This is extremely important. Life probably requires geological activity to get started. Certainly, it's important to keeping a planet habitable by our kind of life (consider that next time there's a massive, damaging earthquake).

So, if geological activity is 'easier', which these results might indicate, then life is easier too. Our kind of life, that is. Other kinds? Who knows. There may be living things out there we would not even recognize as living.
