So, this is an attempt to simplify the known links in the history of human evolution and it’s pretty good as a starting point for learning more about it… but it also presents it in a way that encourages the idea that evolution follows some form of linear progression from one major species to another, and from simpler to more complex forms only (e.g. that evolution has a direction or makes “progress”). This is really bad and leads to a lot of misconceptions and misunderstandings.

I feel like this kind of presentation is similar to the Bohr atomic model in that it’s sort of an easy way to start visualizing and thinking about the topic, but not really an accurate representation of how it works. It will be necessary later to explain the shortcomings of the presentation… which unfortunately leaves some people feeling that they were “lied to” during the initial teaching. It’s not that it’s “wrong” per se, but that it’s simplified to a point that it creates problems.

Don’t talk to the police

Compressions force the blood flow. If you can keep some blood flow through the brain, almost everything else is survivable/fixable. Compressions are 100% vital. Brain tissue dies real quick without blood flow.

Also if you’re doing it right it is fucking exhausting manual labor so switch out every minute if you have another person available. And you will probably break some ribs, that’s just how it is.

That doesn’t mean it can’t be sold to all of the other businesses!
