The Bignews Network is airing a story detailing research by folks at the University of Manchester on bipedalism. The story notes:
For long, researchers have proposed that carrying babies that could no longer use their feet to cling to their parents in the way that young apes can is what made humans bipedal.
But University of Manchester researchers investigating the energy involved in carrying a child say the physical expense to the mother does not support the idea that walking upright was an evolutionary response to child transportation.
Back to visual predation?
