HH - "is it possible to see evolution as a lot of different, very complex developmental processes?"
Yes it is, but evolutionary biology is not about the processes which take place within ONE individual organism (such as a baby growing in the womb).
It is about a genetic game of chance. If say, a wolf has a litter of cubs, they will all be slightly different genetically. They will differ from each other in terms of colour, eyesight, leg length, muscle size, temperament, teeth size etc etc.
The cubs with slightly bigger teeth and coordination (for example) might grow up to be more successful hunters, and catch more food than their siblings. This will give them a better chance of living longer, mating, and passing the genes for big teeth and coordination onto their cubs.
The gene sets that code for 'big teeth' and 'good coordination' will be more likely to survive - ie be 'selected for', and pass down through the generations.
It's not about any one individual, or species, or pre-determined design. It just happened that big teeth and good coordination genes were helpful in the game of wolf survival, so those genes survived and shaped the way that wolves look and behave today.
And it may well be that in humans, the genes which code for a tendency towards 'civilised behaviour' survived at the expense of genes which code for 'just pick a fight with any other human you see'.
