What did you think about the reading?
As I said a fortnight ago, Neil Shubin’s book was a pleasure to read and incapable of straining my attention. Zealous in my reading, I had finished ahead of schedule and regrettably have little to write in regards to this segment.
What did you learn?
Shubin drew to my attention the difference between human sets of teeth those of a reptile. Now when I see a crocodile on the television or in pictures, I am always drawn to the lack of uniformity in their teeth or “precise occlusion” as Shubin says in his book. I also discovered that teeth are the best-preserved part of an animal, contrary to my belief of teeth having equal durability as bone.
What questions do you still have?
If the zone of polarizing activity (ZPA) controls the development and appearance of digits on a limb bud, could it be used to regenerate limbs?
