The walls of these caves are coated with moonmilk, or inch-thick layers of pale bacteria and their whiteish residues. Snottites (from the English word snot)—long, sticky structures with the consistency of nasal mucus that are made of bacteria and threadlike strands of slime—hang like stalactites from the cave ceilings. The floor is crumbly and soft because bacteria have transformed it into an oatmeal-like mass.Got to love 'snottites'!
does away with the Darwinian concept of a tree of life with clear branches that can be used to trace who is descended from whom. In reality, the branches tangle with one another and sometimes rejoin or form cross-connections, even over long distances - that is between organisms including humans, that are evolutionary distant or are even from different domains.The first part of this book, from which I took all the quotes, is extremely interesting, but the main part of the book detailing individual bacteria in depth, didn't hold my attention, not even when I knew about the bacteria like E. coli. I think it was above my head!
Trees can reach a maximum height of only about 425'. It's a physical factor that governs the limit: trees cannot actively transport water. Only when water evaporates from the leaves does the pressure drop sufficiently to allow water to flow upward from the roots. This mechanism doesn't work above this height.I enjoyed the first half of the book very much, it was very detailed, very scientific but full of insights. I think someone with a science background would enjoy the second half just as much.
