Is complex life on a season-less, moonless planet, with two separate and distinct ecosystems possible?

Is it possible for complex life to exist on a planet with no tilt and no moons, and be so close to its sun that the equator would be far too hot to cross on foot and still survive, and its poles far too cold to explore, and yet it would have two distinct habitable zones, or strips, if you will, (one on each hemisphere), between the equator and the poles? If this planet could hold liquid water in deep canyons and and support an oxygen-rich atmosphere, might it be possible that its northernmost habitable strip and its southernmost habitable strip could have evolved two completely different complex ecosystems, both of which evolved complex life, such as humans that never encountered one another, until say, the invention of the airplane and subsequent crossing of the equatorial region to the opposite hemisphere?
