what are ultimate causes of diseases?

Solution

Disease may be defined as an abnormal condition or disorder of human body organ or parts which results in genetic or developmental errors, infection, poisons, nutritional deficiency or imbalance, toxicity etc.

Injury, infection or an unhealthy lifestyle can all make anybody sick. A change in a gene (which tell your body how to make all the different proteins it needs to survive and grow) may cause a change in a protein, affecting the way it works in your body. Some genes are involved in common illnesses, while others cause rare genetic conditions.

Ultimate causes of disease are evolutionary causes which are considered the underlying or real cause. Diseases explained in terms of reproductive success or changes in gene frequencies, or propose an unappreciated benefit for genes is likely an ultimate explanation.
