Biological Disorder: A Reality Since Ancient Times Help
Introduction to Biological Disorder
Apparently, the very earliest people knew a lot about biology! Ancient caves have been discovered in various parts of the world. The walls of many of these caves are richly decorated with pictures of plants, birds, animals, and the humans hunting them.
Over 2000 years ago, the Early Egyptians brushed colorful paintings of living things onto the walls of their temples and coffins. It must have been very important for these people to begin The Search for Biological Order, a search for predictability and meaning in their natural environment. By discovering the underlying patterns of plant and animal structure, function, and behavior, early humans could ensure a more consistent supply of food.
Earlier, we said that a state of Biological Order (particular patterns associated with living things) was an important property of organisms. It is only logical, therefore, for us to assume that ancient people were likewise aware of its exact opposite – Biological Disorder :
Recall that Figure 1.2 showed some patterns representing Biological Order: There was a giraffe with its intricate pattern of black spots, and an S-shaped curve represented a normal range where something (like oral body temperature) remained relatively constant over time.
In a dramatically opposite way, Figure 1.3 (A) represents Biological Disorder symbolically as a dead giraffe without its spots! And Figure 1.3 (B) reveals that a disordered state of something like oral body temperature would be represented by a curve that rose either significantly above its normal range, or significantly below it.
In general, a condition of Biological Order is associated with health and lack of injury. Conversely, a condition of Biological Disorder is often associated with disease, injury, or death of the organism.
A healthy long bone, for example, has a high degree of Biological Order. But a fractured long bone, in marked contrast, reflects a lot of Biological Disorder. From the very earliest days of human existence, bone fractures have been very common. Hence, surely mankind has always been aware of Biological Disorder (broken patterns) of various kinds, even though ancient people may not always have been consciously thinking about it.
