Dawkins mentions this, or maybe indirectly acknowledges it, in The Selfish Gene. Organisms that can pass their ability to adapt on to fast acting nervous centers or even better: large brains, eventually gain a huge advantage. The Great Filter on the other hand, relies on assuming the steps from evolved intelligence (now) to solar system colonization/FTL travel are not only possible, but just a matter of a few millennia or so. Which is a huge assumption.
