Learn about the nature of Extinction with iMinds insightful knowledge series. Extinction means the death of a species of animal or plant. When you think of extinct species, you probably think of dinosaurs. So it may amaze you to know that 99% of all species that once lived on the earth are now extinct!

In this Very Short Introduction, Paul B. Wignall looks at the causes and nature of extinctions, past and present, and the factors that can make a species vulnerable. Summarizing what we know about all of the major and minor extinction events, he examines some of the greatest debates in modern science, such as the relative role of climate and humans in the death of the Pleistocene megafauna, including mammoths and giant ground sloths, and the roles that global warming, ocean acidification, and deforestation are playing in present-day extinctions.

In Extinction and the Human, Timothy Sweet ponders the realities of animal extinction and endangerment and the often divergent Native American and Euro-American narratives that surround them. He focuses especially on the force of human impact on megafauna—mammoths, whales, and the North American bison. Ultimately, he argues, it is the critical assessment of ideas of human exceptionalism that provides a necessary counterpoint both to apologies for human mastery over nature and deep ecology's attempts to erase the human.

Scientists have long attempted to understand Earth’s past, and in service to that effort, they have divided the world’s history into eons, eras, periods, epochs, and ages. For example, the current eon is called the Phanerozoic Eon, which means “visible life”. This is the eon in which multicellular life has evolved and thrived. Before this, life was microscopic (single cells).

A former endangered species biologist looks at the ongoing sixth mass extinction through the prism of human behavior, personal experience, ecology, evolutionary biology, and contemporary conservation efforts. He provides new insights into factors triggering the current mass extinction event and examines conventional wisdom regarding human intelligence. The author suggests—as humanity edges ever closer to disappearing forever—a clear-eyed, real-world rationale for resignation but also acceptance.

Insects are dying off at an apocalyptic rate, or are they? Now there's a way to find out. In this limited series, we go to a remote island rainforest to listen to sound-based research that could reveal the truth about global insect death.

Approximately 200,000 years ago, as modern humans began to radiate out from their evolutionary birthplace in Africa, Neanderthals were already thriving in Europe - descendants of a much earlier migration of the African genus Homo. But when modern humans eventually made their way to Europe 45,000 years ago, Neanderthals suddenly vanished.

The great auk is one of the most tragic and documented examples of extinction. A flightless bird that bred primarily on the remote islands of the North Atlantic, the last of its kind were killed in Iceland in 1844. Gisli Pálsson draws on firsthand accounts from the Icelanders who hunted the last great auks to bring to life a bygone age of Victorian scientific exploration while offering vital insights into the extinction of species.

As global rates of plant and animal extinctions mount, anxieties about the future of the earth's ecosystems are fueling ever more ambitious efforts at conservation, which draw on Western scientific principles to manage species and biodiversity. In Revenant Ecologies, Audra Mitchell argues that these responses not only ignore but also magnify powerful forms of structural violence like colonialism, racism, genocide, extractivism, ableism, and heteronormativity, ultimately contributing to the destruction of unique life forms and ecosystems.

A heady blend of international intrigue, social theory, botanical lore, and ecological study, The Cactus Hunters offers complex insight into species extinction, conservation, and more-than-human care.

If you could bring back one living being from the whole of the history of time, what would you choose? Comedian and former stem-cell biologist Helen Pilcher has thought about this problem - a lot. In Bring Back the King, Helen explains the cutting-edge science that makes the resurrection of extinct animals a very real possibility and highlights her choices from eras gone by, from the king of the dinosaurs, Tyrannosaurus rex, to the King of Rock 'n' Roll, Elvis Presley.

In the early 19th century passenger pigeons accounted for 25 to 40 percent of North America’s birds, traveling in flocks so massive as to block out the sun for hours. Although adults weighed only twelve ounces, they nested and roosted in the millions, destroying large oaks as if hit by hurricanes. Their favorite foods were the seeds and nuts of beech, chestnuts, and other forest trees, but they also raided farmers’ buckwheat, wheat, corn, and rye crops.

The sixth "mass extinction event" in the history of planet Earth is currently under way, with over two hundred species dying off every day. The cause of this seismic event is also the source of the single biggest threat to human life: our own inventions. But for all our talk about sea levels and biotechnology, do we really know what our future will actually look like? Will our immune systems be attacked by so-called super bugs, always evolving, and more easily spread than ever? Will the disappearance of numerous species cripple the biosphere?

In The Last Days of the Dinosaurs, Riley Black walks listeners through what happened in the days, the years, the centuries, and the million years after the impact, tracking the sweeping disruptions that overtook this one spot, and imagining what might have been happening elsewhere on the globe...
