1+1=1 Rovnice života a symbiotická ®evoluce

Rate this book
Kniha jednoduše, stručně a především čtivě seznamuje čtenáře-neodborníka s tím, co to vlastně znamená žít ve století biotechnologií a v čem spočívá ono „kouzlení“ vědců s DNA.Vypráví příběh největšího, a přitom dosti nenápadného objevu biologie, že buňka je vlastně konglomerátem mnoha různých „organismů“, které se v evoluci naučily spolupracovat. Čtenář se dozví, co je v biologii dneška důležité a proč, jak funguje symbióza, co si představit pod poněkud zprofanovaným pojmem molekulární biologie, jak obrovský význam mají v evoluci bakterie nebo jak si vlastně představit buňky, co jsou tyto entity zač a kde se v průběhu evoluce vzaly. Závěr knihy patří úvahám nad smyslem tohoto progresivního odvětví biologie. Nejde jen o hledání teoretické odpovědi na otázku, kdo jsme a kde jsme se tu vzali, ale také o zcela praktické využití biotechnologií v oblasti medicíny, průmyslu či kriminalistiky.

The origin of complex life is endlessly fascinating, and various evolutionary innovations made it possible. This book covers an extraordinarily important moment: symbiosis between existing cells which produced the organelles on which most cells rely. We wouldn’t get far without mitochondria producing ATP for us. And yet it’s been clear to me for a long time that mitochondria had a separate origin. Some of the DNA in our cells exists solely within our mitochondria. That DNA doesn’t even obey the same rules as the rest of our DNA when it comes to producing gametes.

For me, then, this book took something incredibly obvious and broke it down into more steps than I needed. It works to convince you that symbiosis could have occurred. But to me, that’s immediately apparent from the fact that some of our organelles have clear extra-cellular origins. So that aspect of the book was quite slow for me. It’s interesting to read about the research and the people who proposed the theory anyway, though. If you’re into biology and you don’t already know/accept that mitochondria were once free-living bacteria, this is interesting and illuminating!

On a related note (not addressed within the book), it makes me wonder… How do people who don’t believe in evolution handle the existence of mitochondria? They pretty clearly show evolution and co-evolution occurred in the genesis of complex life. If mitochondria weren’t free-living bacteria that adapted to living within simple cells, why do they have their own genetic material? Did God leave it in by accident?

Don’t answer that.

Kniha je písaná veľmi príjemným štýlom, preto po nej môže siahnúť nielen laik, ale aj znalec z vedeckých kruhov.

Na začiatku nás hneď privíta veľmi milá autorova poznámka k českému prekladu. V knihe sa na pár miestach spomínajú aj objavy z našej Karlovej univerzity a som rada, že práve naši prednášajúci a vedci z laboratóri sa podieľajú na tak zaujímavých výskumoch a že aj vďaka ich snahe sa prikladajú kúsok po kúsku dieliky do skladačky a pomáhajú ozrejmiť nové nepoznané končiny.

Autor veľmi pekne a jednoducho vysvetľuje čitateľovi, čo je to bunka, ako bunka funguje, čo je to DNA, ... a hlavne nezabúda na mená vedcov, ktorí stáli za významnými objavmi. Aj keď som biológ, mnohé mená boli pre mňa neznáme a doteraz nechápem, ako som mohla nepoznať napr. Lynn Margulis.

Postupne prechádza zo všeobecných informácií až k tomu, o čom je samotný názov a to problematike endosymbiózy. Odhaľuje koľkými úskaliami museli mnohí vedci prejsť, aby sa nakoniec potvrdilo, že ich teória/hypotéza bola správna. Mňa osobne veľmi fascinovalo ako dlho sa mnohí bránili myšlienke endosymbiózy a že v podstate stále je endosymbióza pre nás veľkou neznámou, ktorá nám ma stále, čo povedať.

Na konci knihy sa spomínaju aj nové záhadne organizmy ako napr. Paulinella alebo tzv. Sea Sheep a tiež sa načínajú témy o sekundárnej endosymbióze, kleptoplastidoch atď ... Veľmi oceňujeme, že autor venoval aj týmto relatívne novým témam dosť priestoru a tak kniha vzbudzuje dojem naozaj komplexného celku.

Ako možné negatívum by sa dalo vnímať, že autor nevenoval viac priestoru fyziológii a biochemizmu týchto organel, ale myslím si, že tieto témy sú tak obsiahlé, že by si zaslúžili samy o sebe samostatné knihy.

Ak sa chcete dozvedieť viac o chloroplastoch,mitochondriach alebo všeobecne o bunkách a máte radi aj trochu histórie v texte, tak určite doporučujem !

Dosud mě snad nikdy nenapadlo, o něčem tak fundamentálním jako je buňka (o níž se vlastně každý něco dozvěděl již na základní škole), uvažovat v souvislosti s evolucí. O to víc mě fascinovalo poznat něco tak zajímavého, jako je evoluce symbiotická.
Samotná kniha je srozumitelná i pro neodborníky. Sice je pravda, že s přibývajícími stránkami značně stoupá i počet odborných termínů, ale autorovi se podařilo zasadit fakta do historického pozadí velkých biologických objevů dvacátého století tak, že vytvořil vcelku čtivý příběh, který mimochodem trvá už čtyři miliardy let.

I probably would have got more out of this book if it hadn't taken me so long to read it because uni got in the way (This was also the reason why I read it in so many stages). Regardless, this is well written, interesting, easy to understand and engaging. It's everything a science book should be. My only criticism is that it, at times, felt a little disjointed, although this might just have been because of how I was reading it.

The (hi)story about endosymbiosis starring mitochondria, the enabler who started it all; and chloroplast, the biggest modifier of our biosphere.
I was familiar with the development of the endosymbiosis theory in the early chapters. So I was more engaged by the later chapters zooming in on cell biochemistry of mitochondria and chloroplast, a dry topic made interesting by linking the mechanical inner workings of a cell with its evolutionary significance.

Zaujímavé a dobre napísané. Prvé kapitoly vysvetľujú všetky potrebné pojmy, ktoré potom autor používa na úvod do endosymbiozi. Autor podáva lekcie nielen o poslednom stave nášho poznania ale popisuje aj históriu kto a ako tieto poznatky formoval.

This book of popular science is a fascinating read. Concise, simply put and told with unpolished excitement, Archibald explains both symbiosis and the process of human discovery which led to our understanding of its necessity to the development of animals, plants and all other eukaryotic organisms.

In short, endosymbiosis occurs when one cell takes in another, smaller cell, with which it swaps energy and nutrients to their mutual benefit. The most important examples of this phenomenon are the mitochondrion and the chloroplast, where cellular respiration and photosynthesis occur. Without such organelles, any life beyond the unicellular would be impossible; indeed, Archibald explains that even complex unicellular organisms may only have developed after early symbiosis between larger bacteria and that which eventually became the mitochondrion.

The book was a superb exposition of these relatively unsung discoveries and, although there were some trifling proofreading errors, the book as a whole was a delight. I would happily recommend it to anyone interested in the history of life from a stage so early, that to call it embryonic would be to overstate its development by more than a billion years.

A quite readable account of how eukaryotic cells gained chloroplasts and mitochondria. It is still a fairly dense topic so most non-biologists are likely to need more than one reading to grasp all that's here. I do recommend it to those with a strong science background and a curiosity about the early evolution of life on the planet and the origins of photosynthetic plants. Quite an eye-opener.

One of the most interesting subjects in the world. I would prefer less namedropping and more facts though!
