Hi everyone! I don't understand the sentence "these behaviours have come about in a different way from vertebrate intelligence". What does it mean?

the context is as follows:
===
Octopuses, in particular, are rated as intelligent. Some carry coconut shells across the seabed to make shelters. <-----Excess quote removed by moderator (Florentia52)----->There have even been cases of them climbing out of aquarium tanks to raid a neighbouring tank that contained a tasty morsel. Many researchers would like to know whether these behaviours have come about in a different way from vertebrate intelligence, or if there are common traits that are necessary for smart creatures of any sort.

    Researchers want to know if the way the octopus (a non-vertebrate) has developed intelligent behaviour has developed in a similar way to how vertebrates developed intelligence or whether it has developed in a completely different way.
