ANSWER: The completion of the Human Genome Project

EXPLANATION:

Human Genome Project (HGP) was completed in April, 2003. Genome varies from one individual to another.

The project involved mapping and sequencing of some people and in other to get each chromosome full sequence in individuals.

However, at the beginning of this project, concerns like ownership and privacy of personal genetic information began to spring up. People are afraid that employers may have access to their genetic information and would reject persons with health issues indicated by their unique genes and health insurance companies may also not provide insurance to people that have deficiency.

In the view of this concern, the United States in 1996 passed the Health Insurance Portability and Accountability Act (HIPAA) which guides against the non-consensual and unauthorized release of health information of individuals.

Explain why evolution is a unifying theme
Setler [38]
Unify means to make or become united uniform, or whole.

(I personally don't agree that evolution is true; but here is my answer)

Evolution is a way Scientists like to theorize the world was made/ created. They try to explain why everything can about in a uniform way. Everything has a reason or theory. Even though scientists haven't been able to prove that Evolution actually exists, many people like the idea of it- just for the reason that it gives a more believable whole approach to how the Earth and Universe came about. For some people, it is more uniform than a religion.

I hope this helped you!
