What do the scientists mean when they say that one
animal species is more intelligent than another? The brain mass compared to
the body mass seems to be important in those theories. Does a mouse have a
larger brain compared to its body mass than an elephant? And if so, is the
mouse more intelligent than the elephant? Does this have relevance for dinosaurs
as well? Did nerve signals travel with the same speed in dinosaurs as in mammals
or birds?
