All true, and impressive considering that we recently evolved from tree dwelling primates but... There are plenty of animals adapted to heat, and can perform similar feats. African wild dogs, dingos and other canines can persistent hunt in similar hot conditions. They're much faster than us, so it's not as extreme a strategy as human "track and spook" methods... but arguably better. Elephants manage to carry those huge, heat retaining bodies. Our Savannah nurseries are full of megafauna like us that live in these conditions effectively.
