IDENTITY: Who Do We Think We Are?

WHATEVER OUR VIEWS ON ABORTION …

DNA sequences and human reproductin provide new scientific base for defining identity

DNA sequences and human reproductin provide new scientific base for defining identity

We can all agree about when life begins

 

This is described by Dr. Maureen Condic (Director for Human Embryology, University of Utah):

  • Following the binding of sperm and egg to each other, the membranes of these two cells fuse, creating in this instant a single hybrid cell: the zygote …
  • Because the zygote arises from the fusion of two different cells, it contains all the components of both sperm and egg …
  • These modifications block sperm binding to the cell surface and prevent further intrusion of additional spermatozoa …
  • Clearly, then, the prior trajectories of sperm and egg have been abandoned, and a new developmental trajectory—that of the zygote—has taken their place.[1]

In other words, the zygote, is immediately protective of itself—a state that will be conserved in the individual until the death of the whole organism. This provides a non-arbitrary definition of when the life of the individual begins and ends.
