The content of this book is very interesting. It is wordy, scientific, and hard to digest at points so it put me in a reading slump. I want to restart it because I was genuinely interested, but this was not a good book to pick after only reading one book the whole year. I will retry again once I get into a more consistent reading flow. The title was a misleading as I expected this to revolve more around the animal kingdom and not so human-focused, but I should have ready the description first before assuming.
