If you want to know more about nature, civilization and the subtle relationships between the two, but you're not a fan of "a single explanation" books, such as "Guns, Germs and Steel", this is the book for you! I liked how the author emphasizes the subtle causal relationships, some of them accidental, to show the history of the world as a complex net of interactions.
• For example, the trypanosoma parasite which travels in the saliva of the tzetze fly, causes the fatal cattle disease. Therefore the initial spread of agriculture had to stop at Central Africa (because the cattle would get infected and die attempting to traverse the tzetze belt), thus leaving the southern parts of Africa alone and allowing the traditional lifestyle to continue and prosper there until the Bantu expansion with their resistant cows. Should we say that the parasite prevented the southern Africa to "develop civilizations", or on the contrary, that it saved the locals from agressive expansions of herders for quite some time?
• Or, look at Australia - it broke off Gondwana 250 million years ago and didn't have any big geological events since. In the absence of geological events the life-supporting minerals from deeper down couldn't get up, leaving Australia's landscape pretty arid. In order to survive in this environment, the plants had to be extremely tough and competitive - like eucalyptus. So when people started planting eucalyptus forests in other places, the plant sucked up all the water and ALL the nutrients, leaving none to the native plants, and so becoming a dangerous invasive species.
Personally I liked the history before humans most. Loved the little Cambrian fuckers, our ancestor piggish lystrosaurus, dimetrodon with his nice innovation of regulating temperature (the "sail" on its back), bacteria and so on.
• "Plants and animals are limited to just two basic modes of energy production (respiration and photosynthesis), yet Prokaryotic bacteria boast at least twenty, allowing them to feed on molecules as diverse as sulphur, carbon dioxide, nitrogen, water, hydrogen, oxygen, iron, ammonia, methane and sugar." Neat!
• A long long time ago all the fuckers from the sea would only eat each other when they bumped into each other. But then the trilobites evolved eyes and life has never been the same. Everyone had to react fast and evolve something in response to the eyes of the trilobites - eyes to see them coming, a shell to hide or spines to defend. Basically everyone's eyes could be tracked back to the arms race with the trilobites. Thanks, trilobites!
• Viruses can be bad (I'm sure I don't need to give an example), but they can also be good, or at least neutral. One of the theories why we have adaptive immunity (cells that can not only fight infection, but also remember the pathogen it won against) is that sharks have been infected with some retro virus, who was "interested" in protecting its host. Due to these retroviruses we all have adaptive immunity, but sharks have the best one, and shark oil is marketed as an immune booster.
Not everyone liked this new thing - deep sea anglerfish got rid of the adaptive immunity in order to practice sexual parasitism (male basically fuses with female after conception).
• Some tens of millions of years ago the Earth was very hot. THEN a type of water fern called azolla made it colder. The fern had a symbiotic relationship with cyanobacteria, allowing them to convert carbon dioxide into nutrients and quickly covered the whoooole arctic region up to Britain, making it a nice swamp and shifting earth's climate. Yay, fern!
• Why are so many bugs so small and have folding wings? Maybe they evolved to crawl into little crevices and hide from an extremely agressive ancient predator with 360 degree vision and the size of an eagle - a big-ass dragonfly!
• Also, oaks are comparable to coral reefs with respect to the amount of species they give shelter / food to. They can also reproduce across species and lace their acorns with tannin, thus encouraging squirrels to hide some of them and not eat all at once (large doses of tannin can be poisonous).
It's a well-structured book, perhaps even TOO well-structured: there are chapters corresponding both to the evolution of life and to certain topics "On Agriculture", "On Biodiversity", "On Sea Life", then 5 - 10 essays in each chapter about the selected species, then the ranking of the species according to their influence on the history of the world. You can read 5 or so essays in one sitting, but reading more requires some effort. The writing style is very appealing, but maybe the structured and fragmentary nature of the book prevents "getting lost in it". Good quality paper makes the illustrations stand out, but also makes to book heavy to carry around.
Despite all that I loved it. I've learned so much and it inspires so much love for the nature that I kinda want to translate it to Lithuanian. Maybe I should?
