Afi talks about secondhand books, and some crabby facts

P/s: 

- I mispronounced forage and some other words

-  L.A. Borradaile coined the term carcinization to describe the convergent evolution process in which a crustacean evolves into a crab-like form from a non-crab-like form

- Factors of evolution or "forces of evolution" is not necessarily environmental pressure. They are genetic drift, gene flow, mutation and natural selection to be more accurate
