Human Hands Evolved So We Could Box...

..according the the New Scientist. David Carrier at the University of Utah suggests that the opposable thumb didn't so much give our ancestors an advantage in tool making and manipulation, but rather enabled the creation of a fist utilising the thumb as a buttress which produces greater striking force.

Popovich angers Stern by resting Spurs' stars, but it's the right call

I love a good ethical dilemma, and Gregg Popovich gave us a great one Thursday night. He benched four of his top players -- Tim Duncan, Manu Ginobili, Tony Parker and Danny Green -- for a national TV game against the Miami Heat.

Popovich has benched Duncan numerous times before, because while they may build a statue of Duncan one day, they don't want him to play like one in May. But Parker is 30. Green is 25.
