Synopsis:  The Alpha Quadrant almost turns into The Brady Bunch.

Memory Alpha Summary:  Maury Povich would have a field day.

Review:  Now this episode is sci-fi at its most complex.  In a very scientific and, frankly, cool way, we discover why most of the species the Enterprise run into look very similar in shape.  They are all descendants of an ancient species, of course.  Unfortunately, the writers painted future Star Trek writers into a corner, as many species in both the Gamma and Delta quadrants also just happen to look like humans.  But it doesn’t negate what they did here.  It’s really not that terribly moving of an episode, probably because it is so deep in discussions about DNA.  But it was cool to see the Federation’s three primary enemies all in one place “working together.”
