As already mentioned in Chap. 5 on systems biology, another astonishing basic
property of life is to build up ever higher levels of regulation and thus of biological
languages (see box). If you look closely, this principle is already indicated in Sect. 3.1.
The ever higher levels allow us to adapt to the environment in an ever better and more
far-sighted way. First jumps to a language level between cells are thus made possible
by the sugar code, this then helps neurons, among others, to come together to form dif
ferent brain tissues and thus to form a brain. The neuronal languages have been
described quite well in many details, starting with chemical synapses (e.g. in our brain),
electrical synapses (e.g. in insects) and the fast electrical conduction via ion channels
along the long sprouts of the nerve cells via axons. However, as can easily be seen in
well-studied brains of, say, humans, mice, ants and bees, it becomes very complex and
unmanageable in the details. In each brain region, there are different mixtures of nerve
cells, different glial cells appear, the ion channels vary (slow and fast, activating and
inhibiting) and since also, really mysterious (see below) new processes become possi
ble, such as our different types of memory.
At the next higher level, languages are used for communication between organisms - in
other words, what we call language in everyday life. This requires a sufficiently complex
brain. However, a few million neurons are sufficient in state-forming insects to use innate
languages across the entire state and also to communicate new observations with this
innate vocabulary, e.g. the already proverbial bee dance for honey sources.

Human language is once again a significant step further developed, since it is newly
learned by a sufficiently large brain, has a very broad vocabulary and also allows the
