The PresentThe three years of this blog presents a mix of evolution and other topics that may lack focus for those wanting the story of evolution, or God, or creativity, or science. My life, in retrospect, seems to bring me to a blend of those topics in a cohesive view not easily clarified for others.
I have not tried to clarify things as much as I should have. In the rush (can one who works at snail or turtle's speed rush?) to get the essential new points presented before they got buried with me, I neglected making all the needed connections and clarifications,
I recently abandoned work on a blog post about the importance of the end products of protein metabolism (primarily ammonia, uric acid, and urea) in the evolutionary transition of animals from aquatic to terrestrial habitats. The uric acid method of storing many toxic ammonia molecules in less soluble, and therefore less toxic molecules, made possible the shelled eggs of vertebrates, and less need for water for elimination of those wastes by birds and insects, Mammals emphasized the conversion of ammonia to urea as a less toxic alternative. But the evolutionary story of these facts are well covered in many basic biology texts.
Many other important facts of evolutionary significance are also well covered in basic texts. But, unfortunately, extreme age of abyssal organisms due to their greatly slowed metabolism, the close relationship of all advanced animals via annelid ancestors, and related facts are missing. Those missing facts are explained in earlier posts during the three years of this blog.
