Atoms are too small to be perceived by the senses. The origin myths of pre-agricultural societies tend to place humans and animals in close relations, while the origin myths of agricultural societies tend describe a separate creation of humans.
Because speciation is so difficult to study, understanding it has long been a primary evolutionary quest. Demographic change, acting through these developmental processes, may also play a role in the changing patterns of disease.
Fossils were actually excavated and put on display in temples in some cases. For example, fever is an appropriate anti-bacterial response that activates some components of the immune system, but, if excessive, can harm the individual. Zoonomia; or the Laws of Organic Life.

From this new form of care came new ways of engaging and understanding each other. Understanding evolution is also central to the advancement of medicine.
Indeed, the entire field of “evolutionary medicine” is devoted to using the. Understanding evolution helps us solve biological problems that impact our lives.
There are excellent examples of this in the field of medicine. To stay one step ahead of pathogenic diseases, researchers must understand the evolutionary patterns of disease-causing organisms.
To control hereditary. An understanding of evolutionary process and evidence is necessary for considering, not only the history of living things, but also many modern questions. For example; Why should we be concerned with a bird-flu epidemic?Download
