why don't other animals build cell phones?
yeah yeah, we have opposable thumbs, and are pretty smart, but we too started by living in caves.
most apes have opposable thumbs, CAN learn language, CAN hold a stick...
Even DOGS pick up on language a little.
Dolphins are super intelligent... maybe smart enough to NOT start their own industrial revolution?
An octapus is super smart, has tons of physical abilities, maybe more than we have with eight suction tentacles...
We have elephants that can paint pictures ....
Beavers BUILD frickin condominiums moving sticks around...
Birds build nests from twigs and navigate magnetically....
How come no other animals are evolving to make their own recordable language, or vehicles for moving faster, or cell phones?
