There is no general reason to expect evolution to be progressive – even in the weak, value-neutral sense. There will be times when increased size of some organ is favoured and other times when decreased size is favoured. Most of the time, average-sized individuals will be favoured in the population and both extremes will be penalised. During these times the population exhibits evolutionary stasis (i.e., no change) with respect to the factor being measured. If we had a complete fossil record and looked for trends in some particular dimension, such as leg length, we would expect to see periods of no change alternating with fitful continuations or reversals in direction – like a weathervane in changeable, gusty weather.

About
Richard Dawkins
Richard Dawkins (born 26 March 1941) is a British evolutionary biologist and author. He is known for his advocacy of atheism.
The second requirement of a virus-friendly environment – that it should obey a program of coded instructions – is again only quantitatively less true for brains than for cells or computers. We sometimes obey orders from one another, but also we sometimes don't. Nevertheless, it is a telling fact that, the world over, the vast majority of children follow the religion of their parents rather than any of the other available religions. Instructions to genuflect, to bow towards Mecca, to nod one's head rhythmically towards the wall, to shake like a maniac, to "speak in tongues" – the list of such arbitrary and pointless motor patterns offered by religion alone is extensive – are obeyed, if not slavishly, at least with some reasonably high statistical probability.
The chicken is only an egg’s way for making another egg.
"Watson retorted: 'Well I don't think we're for anything. We're just products of evolution. You can say, "Gee, your life must be pretty bleak if you don't think there's a purpose." But I'm anticipating having a good lunch.' We did have a good lunch, too."
