The Basics

To be for “life,” we must know when does “life” begins and ends.


When does life begin?

  • At the formation of a new organism, evidenced by distinct behavior and cellular makeup.
  • At the fusion of the plasma membranes of a primary oocyte and a spermatid.
  • Check with Dr. Condic.
  • Check with Dr. Nadal.

Many people realize that beginning-of-life issues are hot topics, but humans at the end of life are no less valuable! End-of-life ethics will become especially important as our nation’s population ages.

When does life end?

  • At the cessation of organismal function, i.e. when the body’s parts cease working for the life of the whole.
