  •  he's not trying to explain the origin (none)
    of the universe et cetera ....

    He wants to know how a blob of undifferentiated cells differentiates and then goes on to become an organism made up of functioning organs.  This is just as fascinating to me as the origin of the universe.  The PBS special about the procreation of the species from conception through birth made me really think about how narrow and precisely balanced the pathway from zygote to a 20 week old fetus is.

    Just pondering how a mammal's circulatory system comes into being is a wonder because without a circulatory system, there is no placenta and without a placenta the organism would eventually perish for lack of nutrients.  So how does it happen?  How does a mere thickening of a vessel wall transform into a four chambered, valved heart without missing a beat?   Can you imagine all the genes switching on and off in perfect sequence with precise timing to accomplish that?

    Sure, PZ comes across as anti-religion but that's because people use religion to avoid science.  So if science comes to uncomfortable conclusions about global warming or common ancestors, then people who don't want to listen can stick religion in their ears instead and listen to that.

    We must never lose it, or sell it, or give it away. We must never let them take it from us.
