I actually did not completely finished this book. I downloaded it to my Kindle from the local library and didn't get it finished before the due date expired. I also couldn't renew it (because there's such a long wait list for it) so I have it back on hold.
I got about 3/4ths of the way thru it tho and I can honestly say I've never highlighted so much in any other book EVER. The entire book is just jammed packed with interesting insights on our history and it's all fascinating but sad too. To see how destructive we've been during our climb to Apex predator ~ wiping out so many species and plants without a thought or care of anything except ourselves. Makes you wonder if we deserve our position on the food chain and what will be left when we're done.
I did not know there have been six different species of the Homo genus identified. I really had only heard of two and when I was much younger, I remember thinking we'd all evolved from one. To think of the changes brought about in our lives as we moved thru the stages of hunter/forager to farmers and now to the cognitive revolution stage and during which stage were we happiest and actually was life the best?? It gave me pause to ponder that it might not be now like I'd anticipated thinking. Definitely connectivity and loneliness were non factors in all the other stages, like they are now. Take the "survival factor" out of living and what is our purpose?? Thought provoking indeed. All these huge jumps during the Cognitive Revolution but we're floundering more than ever at the question of what the goal is of life.
The end of the book (which I skipped ahead & read) dealt with where our species is headed in the future and those contents are both scary and exciting. When the author said that future Sapiens might not even be able to be categorized as Sapiens anymore & will be even more different from us today than we are from the Neanderthals of yesterday, that'sinsane. Collective brains, brains inside computers, cyborgs ~ it sounds like the stuff of science fiction but the research is going on right now! Do I want to be alive to see what that looks like? I'm not really sure. I like aspects of it where health issues and defective genes can be corrected but some of it freaks me out a little. But then again, my phone almost knows what I'm thinking & sometimes that creeps me out.
I'll return & update whenever I get the book back to finish. Very worthwhile and extremely readable even for the non-scientifically minded.
