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 “crab-like” 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.
