Smilodon populator

About #104:

I confess not to have read " Size differences between the sexes tend to be more impressive in species where male aggression is more intense, and in the extinct American lion, size differences between the sexes were even more dramatic than in lions living today. "

I understood "sexual dimorphism" in African lions, not only the size difference between males and females but also the presence of the male's mane. But the account seems to be essentially focused on the size difference between males and females (logical if we consider the case of an extinct specy).

That being said, I didn't believe that the size difference between sexes was greater among lions than among tigers. Thus, are tigers especially macho too ? Tigers are solitary animals but the males don't seem to be as rough towards females as in the case of lions. Reply
