Alright, reading blows, I understand. But this book is freaking amazing and ties in and adds so much information for what we are learning about now. It doesn't have the link to business, but that's where it's up to you to make the connections. Your Inner Fish by Neil Shuban follows the perfect transitional species between fish and amphibians, the Tiktaalik. It goes over deep homologies and bone structures and I believe it covers the Sonic Hedgehog Gene I mentioned in class. It is incredibly interesting and I am not one who likes reading biology books, but this is definitely worth it. I believe it is only a $10 book, but just reading these summaries will probably suffice.
Also to make it easier, you can check out the Sonic Hedgehog Gene here, super interesting.
