If I were hired as a genetic counselor to advise a couple about the odds of the couple having a baby with a genetic disorder and I wanted to order lab tests to be done on the pregnant mother to determine if the baby has a genetic disorder (amniocentesis)-what kind of test would be done? How would the test determine if the baby has a genetic disorder or not? If it is determined that the couple's baby has a genetic disorder, then what advice should I provide to that couple? Why? What if the couple went against my advice? Whose advice (mine-the genetic counselor representing science or the couple representing society) should be considered?
One species eventually changes into something completely different over the course of millions of years. This can be described using the evolution theory. The evolutionary process of species shows how one population of a species changes over time to the point where that population is distinct and can no longer interbreed with the parent population. Hence one species is changed into another over o period of time. Speciation is an evolutionary process by which a new species comes into being.
This theory of evolution was proposed by Charles Darwin.
