That "lecture" about the inexplicable changes in evolutionary mutations broke my brain. I'm not sure, but I seem to recall that I actually once read about the anglerfish's evolution. And the fact that Robin's mentor can't imagine how a small development of the fish's fin might have helped him doesn't make it impossible that it did; also it's not like the boxer crab's ancestor suddenly started to pick up sticks and what not and luckily picked up the right things to survive.
I get what this portion was getting at, but still. Listening to that felt wrong, as if this wasn't Sigler, but some lesser pseudo-author.
