I don't think "biologically" is exactly the right word, but yes. It's not something that can be found under a microscope or in the DNA. But it is a congenital condition common to all humans.
Adam and Eve were created in Eden. When they were expelled, all of their descendents have been born outside of the garden.

So it is a spiritual condition? If it's not passed on genetically (which I didn't think you'd argue), why is it that Jesus is not the bearer of grace to all mankind in the same way Adam was the bearer of sin?
