<DIV><FONT size=2 face=Arial><SPAN class=250395604-03112009>Mitochondria have
their own DNA. This has led me to speculate that way back in the old days
when life was all single cell, the mitochondria were a separate species that
infiltrated some larger cells. The two species somehow formed a mutually
beneficial relationship with the mitochondria losing their defensive and motor
mechanisms. The larger cells feed the mitochondria sugars, they
metabolize it into ATP and give it back, together they made supercells, which
were eventually able to join with other supercells to form really cool
lifeforms. I need to study up on this; it might already be well
understood.</SPAN></FONT></DIV>

<DIV><FONT size=2 face=Arial><SPAN class=250395604-03112009>Most of the time
when we think of animals, we imagine mammals, but when you really look, you
realize that mammals are all pretty much the same thing. If you dissect
any number of different examples, you find pretty much analogous organs in
pretty analogous places. It doesn't require a dozen different degrees
to be a veteranarian. </SPAN></FONT></DIV>
