Etymology of word work (praca). Apparently it is descended from Upper Lusatian word prĂ³ca which meant suffering. It explain a few things.

The first revolt is against the supreme tyranny of theology, of the phantom of God. As long as we have a master in heaven, we will be slaves on earth.

RE: What Did You Learn Today?
I'm reading the new book Chimpanzees and Human Evolution (2017). The book discusses how, at one time, chimps and gorillas were grouped together as a monophyly, meaning they shared a common ancestor apart from humans. However, genetic research showed humans and chimps are more closely related to each other than they are to gorillas (a common fact). But the one thing that most intrigued me is that, while gorillas, chimps, and humans all share a common ancestor, the phenotypic differences between the former two are a simple matter of time. Gorillas are obviously larger and more robust in certain areas, such as the skull, than chimps. But analyses show that both genera have different growth rates over time. For example, young gorillas have a very similar structure to adult chimpanzees. This difference in allometric expression led to one famous paleontologist to refer to gorillas as "overgrown chimpanzees".

The book itself analyzes genetic, fossil, anatomical, and behavioral evidence to show that chimps are the best model for what our Last Common Ancestor (LCA) looked like. The gorilla's size is a derived trait and not a primitive feature of the LCA.
