Crabs are much more likely. Everything turns into crabs, eventually.
"Everything" with our sort of molecule for storing information. DNA might not be the only way.
It's not about DNA; it's about βcrab-likeβ being an optimal shape for something that has to move itself in and manipulate a variety of environments.
It doesn't matter if it's an arthropod or a robot. Crab-like is almost always optimal.
Optimal for Earth environments.
A crab body would not work if life evolved on a gas giant.
