Often we define intelligence with respect to human qualities. Thus, as we tend to consider ourselves as the most intelligent species, we compare other species to ourselves.
Technology automicatically indicates intelligence.
An absence of technology translates into an absence of intelligence. There is no certain basis for the assumption that all intelligence is human-like intelligence. Indeed, there are undeniable trends, such as large brains in mammals and larger neocortices in primates, but to generalize these correlations cannot always be done. Truly, intelligence seems to be relative, in that it evolves to fulfill the needs of the particular species. Evolutionarily speaking, scientists agree that organisms seem to have become more complex behaviorally.
