Quote:It has sometimes been assumed that social species, such as lions, should have larger brains than solitary species, such as tigers, because of the need to handle a more complex social life within groups or prides. However, despite a few studies suggesting a relationship between big brains and sociality in mammals, evidence for the link is far from clear.

@TheLioness As it is clear from the article that social structure does not mean a larger brain. But As I know the most intelligence animals in the worlds are social , for example Chimps, Orangutan, dolphin, crows etc . In animals world from human point of view larger brain is symbol of more intelligence as there is no way to take I.Q test of animals in normal condition.

 

The article states the tiger having the larger brain, but no indication of them being more intelligent.
A 200 kg red deer had a brain weight of 435 grams, I don't doubt herbivore intelligence, but I would bet the carnivores, even the smaller leopard of 46kg with a brain weight of 157 is smarter than the deer.

"The volume of the cranium is used as a rough indicator of the size of the brain, and this in turn is used as a rough indicator of the potential intelligence of the organism. However, larger cranial capacity is not always indicative of a more intelligent organism, since larger capacities are required for controlling a larger body, or in many cases are an adaptive feature for life in a colder environment."

It is hard to really answer the question who is smarter with just brain size is all I'm saying. I for one would like to know more on this subject, however I could be wrong a tigers could be smarter, however like I mentioned it could be th opposite.
