Do you think we should send a probe through a black hole?

On Human Universe you described the cycle of the earth's wobble as a cause for massive climate change also coinciding with human evolution and the increased size of our brains (x2). If our current, self induced climate change reaches the same peak of catastrophe, is it possible that due to survival processes humans would go through, that this could also cause an evolution in our brain size etc.? Even though it wasn't part of the natural cycle?
