Whoa! Marsupials for their smaller braincase size are incredibly 
intelligent.Some comparative studies trying to see the intelligence of 
some marsupials have shown that many are smarter than your common 
eutherians. They also have a higher learning capacity. I happen to own a 
pet marsupial, a sugar glider ( _Petaurus breviceps_) and it is not only 
smart, it is has very acute sensory abilities ( I've seen it jump and 
catch things in mid-air in very, very dark areas.) That statement that 
you made above is very wrong. Marsupials are not inferior in their 
intelligence, sensory ability, or reproduction ( the marsupial 
reproduction though it produces far less offspring, is very easy on the 
mother and produces a more stable species community).
