QR6.2 Evolving a Brain

Our brain has more nerves than there are people in the world or devices on the Internet and as one nerve can link to 10,000 others, it also has more connections than the Internet. This is not surprising given that it took five hundred million years and an unimaginable number of lives to evolve but it is easy to forget that the brain had to function at every step. A bee brain is just a neuron sliver but it lets bees fly, form colonies and even talk to each other. Brains like ours could only evolve from brains like theirs if they survived. Imagine building a jumbo jet where the first part had to fly and the same applied for every part added after that. Or imagine writing a program where the first line of code had to work or you didn’t get to write the second. We know how to build an information processor but not how to grow one.
