The two options that would support the idea that humans and dogs evolved from a common ancestor are:
1. **They both had a tail as an embryo.** - This suggests a shared developmental trait found in their embryonic stages, which can indicate common ancestry.
2. **Their arm and leg structure is similar, but may have a different function.** - This reflects homologous structures, which are anatomical features in different species that have a similar origin but may serve different functions, supporting the idea of a common ancestor.
The other options do not provide evidence for a common ancestor between humans and dogs.
