And now I want to talk about the amniotic egg.
Fish can produce very tiny eggs.
And a little couple of a millimeter long fish can hatch outand can find food and survive in the aquatic environment and grow up to be a great big fish. Wedon't see any examples of that among vertebrate animals. What we see instead is an alternate solution. And that is the evolution of this amnioticegg. Which is an egg that if you really look at it in the big sense of the thing, what this egg isdoing is allowing vertebrate animals to produce larger newborn young than they would be able toproduce otherwise.
