That's because there's land here, but what about a planet with only water, or just not enough land. But maybe water-surface-only (no land surface) is unlikely

- manmal 2y agoThere would still be enough earth like planets with land.
- oersted 2y agoWhy would water prevent the evolution of hands? Lots of sea creatures have claws. The sea is also not all that different from an atmosphere with a higher density in principle, we live "under-air".
- cutemonster 2y agoLooking at this planet, it's less likely to happen. Maybe high density (water) makes tools less useful, and thus hands less useful, since you cannot move a tool particularly fast under water, compared to on land. I suppose you've tried throwing a stone underwater -- compare with throwing on land. From this seems to follow, that creatures with human like intelligence, are less likely to appear, if the density of the liquid or gas surrounding them, is too high. (Dolphins are bright but not that bright.)
