Why is it important to study evolution and from where organisms have originated

1. it is important to study evolution in order to solve biological problems that impact our lives.

2. it is also important to study evolution in order to  stay one step ahead of pathogenic diseases and able to find solutions to it

Researchers must understand the evolutionary patterns of disease-causing organisms.

It is noted that all life on Earth evolved from a single-celled organism that lived roughly 3.5 billion years ago.

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.  

the answer is d p: cell, q: organ, r: organ system, s: tissue
