In its evolution from a more primitive nervous system, the brain, as an organ with ten or more billion neurons and many more connections between them must have changed and grown as a result of many accidents.

In an extreme view, the world can be seen as only connections, nothing else. We think of a dictionary as the repository of meaning, but it defines words only in terms of other words. I liked the idea that a piece of information is really defined only by what it's related to, and how it's related. There really is little else to meaning. The structure is everything. There are billions of neurons in our brains, but what are neurons? Just cells. The brain has no knowledge until connections are made between neurons. All that we know, all that we are, comes from the way our neurons are connected.
Tim Berners-Lee
Evolution is all about processes that almost never happen. Every birth in every lineage is a potential speciation event, but speciation almost never happens, not once in a million births. Mutation in DNA almost never happens -- not once in a trillion copyings -- but evolution depends on it. Take the set of infrequent accidents -- things that almost never happen -- and sort them into the happy accidents, the neutral accidents, and the fatal accidents; amplify the effects of the happy accidents -- which happens automatically when you have replication and competition -- and you get evolution.
Daniel C. Dennett
In the elemental emotions of fear and rage associated with the most primitive parts of the brain, this swift response without conscious intervention or direction is a condition of survival: but something more than survival comes forth from it; for this very automatism freed the growing brain and ramifying nervous system for more important services, detached from the immediate pressure for survival, performed by the new brain. Here by his conscious symbolic activities man created a second realm that conforms more closely to his higher personal and social needs.
Lewis Mumford
The evolution of the brain not only overshot the needs of prehistoric man, it is the only example of evolution providing a species with an organ which it does not know how to use.
Arthur Koestler
Evolution embodies information in every part of every organism. ... This information doesn't have to be copied into the brain at all. It doesn't have to be "represented" in "data structures" in the nervous system. It can be exploited by the nervous system, however, which is designed to rely on, or exploit, the information in the hormonal systems just as it is designed to rely on, or exploit, the information embodied in your limbs and eyes. So there is wisdom, particularly about preferences, embodied in the rest of the body. By using the old bodily systems as a sort of sounding board, or reactive audience, or critic, the central nervous system can be guided - sometimes nudged, sometimes slammed - into wise policies. Put it to the vote of the body, in effect. ...
