Darwin (and, at the exact same time Alfred Russell Wallace) proposed a mechanism of how that change occurs -- Natural selection. Natural selection is one of several mechanisms of evolution. We now know that the rate of evolution differs hugely throughout the evolutionary history of species. For example, sponges (primitive marine animals) have been mostly unchanged for about a half of a billion of years, while some bacteria evolve antibiotic resistance within months or even days.

Darwin's understanding was somewhat limited, but the core idea of evolution, and even its main mechanism, natural selection, has remained well supported in light of all new information on extinction etc. (less)

Later chapters have interviews with people who have either published findings (such as the concept of the K-T extinction, formation of the anthropocene extinction idea) or who are in the middle of the research (at the Great Barrier Reef, in the forests of Brazil). These people share with us their views on what is happening and what will happen in the near future, so even if something described can't be labelled as a fact, it sounds factual and everything seems to be an educated conclusion.(less)

Looking for a good horror novel that will keep you up late at night? One that features the most remorseless, inventive, and successful serial killer to ever stumble into the written word? One whose body count grows exponentially as his appetite becomes more ravenous, never sated? One who is so adept at killing that he does so without even seeming to try?

Ecocides could only be justified with the primate madness gene in Prehistoric times, but nowadays it´s inexcusable.

Archaeologists of the future in millions of years would wonder what has happened, how such devastation could be done in such a short time. They compare volcanic eruptions, climate change, meteorites, changes in the earth's magnetic field, solar storms, gamma ray bursts, etc. with the unique event or people find the ruins of a vanished high culture in the course of the colonization

There were some interesting moments but they were too few to compensate.

Better Dead Than Read

In the Book of Genesis, God creates mankind last, as if anticipating the theory of Darwinian evolution. But the text is somewhat ambivalent about his accomplishment. Whereas all his other creations - time, space, light, plants, sentient creatures - are explicitly deemed ‘good,’ human beings are merely lumped in with everything else as God surveys the world. The biblical author seems to be hedging the blessing (mitzvah: both a command and a favour) of human ‘rule’ over ever

Dial M for Murder

This is a dark and deeply depressing book, trying hard to be hopeful — on the lines of Douglas Adams' Last Chance to See.

Kolbert's book reminds us that we could be the last couple of generations to witness true diversity, maybe the last to see such magnificent and delicate creatures as the amphibians.

The story of the Sixth Extinction, at least as Kolbert has chosen to tell it, comes in thirteen chapters. Each tracks a species that’s in some way emblematic — the American mast

This book is a very engaging examination of extinctions of animal species through the ages. Elizabeth Kolbert adds a wonderfully personal touch to many of the chapters, as she describes her visits to the habitats where various species are dying out. She accompanies scientists and ecologists as they delve into extinctions, past and present. Some biologists are gathering up endangered species, putting them into special reserves and zoo-like habitats where they might be able to survive.

*hides in apocalypse-safe bunker and cries*

A goosebump-inducing nonfiction read! The Sixth Extinction is told in a part textbook, part narrative style; the author gives readers hard facts mixed into detailed personal accounts of her research trips. In 13 chapters, she tells the stories of several species, some long extinct, some still teetering on the brink of extinction, all with one common enemy - us.

The best part of the book is that Kolbert isn't trying to blame the human race or make her re
I shied away from reading this for a while imaging that it would be, nay should be, grimmer than the grim saga of Grim Grimson the grim from Grimsby. But it is not, because the unrelenting grimness of the mass extermination occurring now is overshadowed by the relentless bounciness and vigour of the narrative style, if I were to descend in to crude stereotypes (view spoiler) then I would say that is is b ...more

I've read a lot of non-fiction books that are dry and sometimes gets bogged down in details and others that are very engaging but rather light on the meat. And then sometimes, you get a very cogent work with a very rich sampling of science from all different quarters laid out in such a way that it is impossible to believe anything BUT the final summation.

This is one of those works. We are in the middle of the sixth extinction event on Earth. The final result of the dieoff, as of just how many mi

In this well-researched book, science writer Elizabeth Kolbert casts a strong light on the damage humans are doing to planet Earth. In one example Kolbert describes declining populations of the golden frog, which is rapidly disappearing from all its native habitats. Turns out humans have inadvertently spread a type of fungus that infects the skin of amphibians and kills them.

“Though it might be nice to imagine there once was a time when man lived in harmony with nature, it’s not clear that he ever really did”—Elizabeth Kohlbert

I finally slow listened to this award-winning and depressing book written by a journalist who helps translate for scientists the truth of our current Anthropocene era:

The Anthropocene is a proposed epoch dating from the commencement of significant human impact on Earth's ecosystems including, but not li
This book both awed and depressed me.

From page one, Kolbert writes an impressive survey of how destructive mankind has been to the planet. She gives a brief history of the five mass extinctions that have happened, and travels around the world to report on species that are currently going extinct. But the big problem now isn't a giant asteroid -- it's humans. We are such a lethal force that we can unwittingly (or just greedily) wipe out entire species at alarming rates.

A well balanced tour of apparent causes for five past massive extinctions and for the current epoch of the human-caused “Sixth Extinction”. The relatively sudden acceleration of extinctions has a lot of consensus among scientists as defining a new age, the “Anthropocene”.

One of the most important science books written in the past five years. Kolbert synthesizes science and history effortlessly here.

I kind of view this as Guns Germs and Steel v2, with the focus on the mess we humans have caused and the lengths scientists are going to in order to both understand and hopefully minimize the damage. Excellent individual chapters on the different species of flora and fauna that we have lost recently or are in the process of losing due to the anthropocene era, that is
Kolbert’s premise, that we are likely in the midst of the Sixth Period of a great extinction in the world’s history, is “a most awful yet interesting” idea, to quote Darwin out of context. Kolbert shares recent (in the past forty years) scientific discoveries, theories, and test results which many of us may not have had a chance to follow with the diligence of a scientist. She is not a scientist but a journalist who has interviewed scientists, and her wonderful easy style makes it simple for us ...more

As most will have realized by now, I declared this March nature/science month. Thus, I'm reading (mostly) only non-fiction books. Many of these are about what was originally known as "natural history", which later became several scientific fields. There are a lot of books about this subject, of course, but I decided to finally catch up on the classics (Darwin, Wallace, Humboldt) and take it from there. Humboldt was the father of what we nowadays consider environmentalism and it was therefore onl ...more

Kolbert makes a compelling case that we are in the throes of a mass extinction citing example after example of our destruction of the environment and its inhabitants. Fortunately she is a gifted writer, so despite the bleak message we don’t just put down this important book in despair. Reporting on scientists investigating threatened species, she identifies the many ways that we are putting all life at risk. Sometimes our unrestrained native instincts are responsible, others the shortsighted and ...more

Most depressing book that I've ever read. The physical science of man's injury to Earth began since he emerged as a species, and now is at its zenith. In spite of the evidence, not much is being done to reduce the damage. I felt sicker and sicker as I read on, and I hated picking the book up once I'd put it down. As a species, humanity is self-serving and aggressive. I've watched Trump pooh-pooh climate change, knowing that our oceans are becoming acidic which is going to kill off microscope mar ...more

I often find that engineers (who sometimes believe they are demigods), go berserk at the mention of Greta Thunberg. How dare this child who does not know anything about science, make such statements about climate change? How dare she tell the world to make a paradigm shift and stop using fossil fuels? And - this is the most heinous crime of all - how dare so many people follow her? If there is a problem because of carbon emission (and they are sure there isn't) engineers would find a way out of ...more

This one should be required reading in highschool. It will teach one more about the world and humanity than The Scarlet Letter or its ilk ever could. It's a book about wonder at the natural world and evolution, and a walk through of why most humans suck at sharing the globe.

My initial reaction:

Then I had a good cry.


(Full disclosure: book abandoned at page 173 [out of 269 pages].)

This book isn’t bad, and it’s definitely important--everyone should learn about the topic--but Kolbert isn’t an engaging writer, and engaging writing is crucial for such an involved topic. I was deceived because The Sixth Extinction starts out promising and my interest was piqued immediately; however, subsequent chapters go downhill. The first chapters discuss species now extinct, specifically the Panamanian golden

Wide ranging exploration of species extinction. The first half of the book covers how we came to understand the history of mass extinction. The second half probes the human role in the current sudden rise in animal and plant extinctions- especially through our role in driving global warming and ocean acidification.

While Kolbert's information here is frightening, her presentation is understated and she studiously avoids politics. This is a work of science journalism, not environmental advocacy.
