A new study has found that, not only the human, but, male kangaroos too flex their biceps to impress the opposite sex. It is observed that the male kangaroos frequently adopt poses to show off their muscular arms to females. A research by Murdoch University and Curtin University in Australia found that the arm and shoulder muscles of male kangaroos play a key role in attracting members of opposite sex. Hence, a male kangaroo’s forearm size could be a sexually selected trait and help them find a mate.
