Muscly arms helps roos attract the ladies
Bulky forearms make male kangaroos more attractive, according to new research.
IT APPEARS HUMAN males are not the only ones that stack on the muscle to draw in the ladies.
A new study suggests that the size of arm and shoulder muscles in male kangaroos are not only used for fighting, they could also be key to attracting the opposite sex.
Dominant male roos will even go one step further and display their forelimb muscles to attract females, the study suggests.
Bulky kangaroos more attractive
Lead researcher Natalie Warburton, along with a team from Murdoch University in Perth, studied populations of western grey kangaroo (Macropus fuliginosus) around Perth and Dunsborough in Western Australia.
The forelimbs of the male kangaroos were found to be disproportionately large for the size of animal, when compared to the muscles of the female. Natalie says the developed forelimb muscles “could be linked to the fact that male kangaroos establish and maintain their dominance hierarchy through sparring contests that involve grasping their opponent and using their back legs to box them.”
