Are there evolutionary patterns related to the evolution of size? If so, how do we make sense of these patterns? And what are the largest living systems that have ever existed?
Why are there no credits provided for the images that you use?
There is no good answer other than not being aware that I needed to when I started writing. Since then I assumed that if I wasn't making money off of a post it wasn't necessary. But I should moving forward.
I agree that your use of the images would qualify as "fair use." But it's still a good idea to give credit where's it's due. btw, I enjoy your writing. Keep up the good work!
Why does the arc of evolution bend towards complexity? Is there a logical explanation as to why this is beneficial or why it occurs? I know the question implies human motives to the evolutionary process, but it seems counterintuitive in a way.
Evolution tends towards more complex forms because usually what is being selected is greater functionality (i.e., eyes that can see better/clearer/in different environments, etc., or limbs that can help you run faster, etc.) depending on the organism and the selection pressures. Usually greater functionality requires greater complexity (i.e., more specialized cone and rod cells). However, as a paper this year demonstrated you can also get greater functionality from "subtraction" or less complexity. I wrote about it here.
