The brain — Helen Phillips
The brain is often regarded as the highest achievement of evolution, which gave mankind's ultimate skills such as language, intelligence and consciousness. But before all this, the brain's evolution has made some amazing things: it is life beyond the realm of plants. For the first time as the organism's brain provides a smaller generation time scale can be a means of dealing with environmental changes.
Nervous system produced two very useful features: movement and memory. If you are a plant food sources are scarce, but, that's enough. But if you have to control the muscles of the nervous system, in fact you can walk around looking for food, and shelter.
The most simple nervous system is the only remaining to stab cells of animals (cnidarian) — jellyfish, sea urchins, anemones — in ring-loop. These gadgets might not very smart, but they still can rely on this to find yourself, and be able to achieve more than plant way of fine living patterns in the world.
The next evolutionary stage probably occurred in the Cambrian of flat worms, added some control system allows movement freer freely. The original brain are just a few extra lines to help organizations (nerve) network.
Equipped with these things most early aquatic animals, hunt as a priority. Organisms need from toxic foods selected nutrients, the brain can help them do that. There is no doubt that you go to see any animals, will find that the brain is always near. In some very original invertebrates, some even just after the brain to the esophagus.
As the brain to produce judgement, to discover that the world is good or evil, but also the emergence of memory. These capabilities together to allow animals to real-time monitoring event developments (is better or worse). Their role is in turn makes a simple forecasting and compensation systems. Even a simple brain animal--insects, slugs, flat worms — can use their experience to scheduled next what's worth doing or what most of the food, they have an enhanced selection behavior of the reward system.

The human brain is more complex functionality — for example, social interaction, decision-making skills, empathy — appears to be the basic control intake of the food system evolution. Control what we decided that feeling into intuitive judgment (in English is called the gut instincts and intuition of the literal translation is the belly). The frontal cortex (frontal cortex) is the most highly developed social contacts handles resolutions and behavior, and that happens to adjacent to the supervisor of taste, smell and mouth, tongue, bowel movement in the region. We kiss become your spouse's people for a reason — it is our knowledge of inspection of things the most original and simple manner.
