Living organisms have very organised structures.
Everything depends upon the way that the different parts of their bodies work together.
The parts of this watch work together, so that the hands of the watch move round in a rhythm that we use to tell the time. The hands do this because of the precise organisation of all of the parts of the watch.
The ability to tell the time emerges from the watch, only when all of the parts move together smoothly. If anything goes wrong, the watch “stops” and the ability to tell the time disappears.
Living organisms are alive because they are organised. Everything depends upon the way that the different parts of their bodies work together.
For an organism, life emerges and exists for only as long as its parts work together smoothly.
If anything goes wrong, the organism becomes ill. If it is very serious, then the organism dies and its life disappears. This is difficult to think about, but it is a fact of life.
- One of the important features of human society is that we have learned how to care for the sick and the elderly. Hows does this help the survival of humanity?
