You might also do some homework and watch his video on basic body plans ahead of time.

Evolution, development, and random biological ejaculations from a godless liberal
The speculation around 28:00 on metamorphosis is interesting re the rearrangement of parts.
I assume this is more about amphibians than insects. To my inexpert self, caterpillar->butterfly looks almost like a delayed version of growing a chicken: the caterpillar’s job is just to build up a large enough sack of raw material to build the real animal, with the other parts (e.g. legs and mouth) just totally discarded rather than rearranged. I know nothing about amphibians though.
Enquiring minds want a video on metamorphosis. Pretty please.
What do you think of Richard Wrangham’s idea of cooking driving the evolution of intelligence. (David Owen: “We don’t know what it is but we’re getting better and better at measuring it.” ;-) )
