Question

Geneticists find Iceland a living laboratory for the study of _____ because virtually all of its current 300,000 citizens descend from less than a thousand Icelanders who survived the medieval Black Death.

a. diversity
b. revivification
c. therapy
d. history
e. mutation
f. rejuvenation

Answer 1

The correct answer is option d. history.

Step-by-step explanation:

Geneticists find Iceland to be a unique living laboratory for the study of human genetics and evolutionary history because nearly all of its current population of around 300,000 citizens descend from a small number of survivors of the medieval Black Death. This situation makes Iceland particularly useful for studying the genetic history and the effects of genetic drift in a relatively isolated population.

The principles of genetic inheritance allow scientists to investigate how genetics, environment, and disease have shaped human evolution throughout history. For example, ancient human migrations and selective pressures from diseases like the Black Death can be explored by examining the genetic makeup of modern populations, which carries the legacy of these past events.

The research in Iceland can help in understanding the conditions that influenced genetic variation and the survival of certain alleles, such as those influencing immune response or adaptation to new environments.
