How did intelligent life got so advanced on land (humans) than in the oceans considering how the ocean is the greater part of the world and has much more diversity in it?
In: Biology
The ocean is easier to survive in than on land, as a result there is less selection pressure in general and marine life tends to evolve more slowly than land animals.
You have buoyancy and pressure to help maintain your body shape, you can move in three dimensions, your eggs aren’t at risk of drying out, you can shoot your load anywhere and have a decent chance of fertilising some eggs.
You are resistant to many extremes of weather, there are never droughts or floods underwater. Storms only really affect the top layer. Even earthquakes and volcanic eruptions are much easier to survive underwater.
