“The Earth is what we all have in common”*…

Ancient Gateway, Angkor, Cambodia

There’s a pervasive notion in our society that nature is something outside, over there, other, from what we are as humans. From religious texts teaching that God provided humans with dominion over Earth, to futuristic literature pitching nature as our past and human ingenuity and technology as our future, the narrative that humans are beyond – or even superior to – nature is deeply entrenched.

This separation, this othering of nature, has arguably enabled our rampant destruction of the rest of the living world, and even led some to claim that our human nature is incompatible with nature itself.

Now a huge international study involving geography, archeology, ecology, and conservation adds to the wealth of sciences that exposes this idea as the lie it is.

Researchers found that for most of our history, humanity has lived in equilibrium with our world, despite us having altered most of Earth’s terrestrial surface far sooner than we realized. “Societies used their landscapes in ways that sustained most of their native biodiversity and even increased their biodiversity, productivity, and resilience,” said University of Maryland environmental systems scientist Erle Ellis.

Analyzing reconstructions of historic global land use by humans and comparing this to global patterns of biodiversity, the researchers found that by 10000 BCE humans had transformed nearly three-quarters of Earth’s land surface – you can view an interactive map of their findings here.

This upends previous models that suggested most land was still uninhabited as recently as 1500 CE. “Lands now characterized as ‘natural’, ‘intact’, and ‘wild’ generally exhibit long histories of human use,” University of Queensland conservation scientist James Watson explained.

“There’s a paradigm among natural scientists, conservationists, and policymakers that human transformation of terrestrial nature is mostly recent and inherently destructive,” said Watson.

In recent times, it’s certainly appeared that way, but clearly this hasn’t always been the case – humanity’s presence hasn’t always caused the life around us to wither away. The researchers note that in many areas, mosaics of diverse landscapes managed by people were sustained for millennia.

They used strategies like planting, animal domestication, and managing the ecosystems in a way that made the landscape not just more productive for us, but helping to support high species richness too. “Our study found a close correlation between areas of high biodiversity and areas long occupied by Indigenous and traditional peoples,” said Max Planck Institute archeologist Nicole Boivin.

“The problem is not human use per se, the problem is the kind of land use we see in industrialized societies – characterized by unsustainable agricultural practices and unmitigated extraction and appropriation.”

“We need to recognize that some types of human activity – particularly more traditional land management practices that we see in the archaeological record or practiced today by many Indigenous peoples – are actually really supportive of biodiversity. We need to promote and empower that,” said Bovin.

University of Maine anthropologist Darren Ranco noted that while indigenous people manage around 5 percent of the world’s lands that currently contain 80 percent of the world’s biodiversity, they have been excluded from management and access in protected areas like the US National Parks.

These findings make it clear that we need to empower Indigenous, traditional, and local peoples who know their lands in ways science is only just beginning to understand, explained Ellis. While no one is suggesting we revert to technology-less societies of our past, the idea is to learn from different ways of living that have proven track records of longevity.

From there, we can find new and better ways forward with the help of our advanced technologies, and a big part of this is recognizing that we are part of nature just as nature is a part of us.

Learning from our ancestors: “Humans Shaped Life on Earth For 12,000 Years, And It Wasn’t All Doom And Destruction.” Read the research in full at PNAS.

By way of an illustration of the issue, “Climate crisis has shifted the Earth’s axis, study shows“:

In the past, only natural factors such as ocean currents and the convection of hot rock in the deep Earth contributed to the drifting position of the poles. But the new research shows that since the 1990s, the loss of hundreds of billions of tonnes of ice a year into the oceans resulting from the climate crisis has caused the poles to move in new directions.

Indeed, we’ve moved the poles 4 meters since 1980…

As we find balance, we might spare a thought for Jean Nicot de Villemain; he died on this date in 1604. A diplomat and scholar, he introduced tobacco to the French court (and thus, into wide usage in Europe). In 1560, while serving as ambassador in Portugal, he was shown a tobacco plant in the garden of Lisbon botanist Damião de Goes, who claimed it had healing properties. Nicot applied it to his nose and forehead and found it relieved his headaches.

Nicot sent home seeds and leaves of tobacco, recommending its marvelous therapeutic value. He then sent snuff to Catherine de Medici, the Queen of France to treat her migraine headaches. She was impressed with its results, and became an advocate.

The tobacco plant, Nicotiana tabacum, and its active substance, nicotine, derive their names from his.

Nicot also compiled one of the first French dictionaries, Thresor de la langue françoyse (1606).

The prevailing belief in a separation between humans and everything else is an essential function of a contemporary global economy which has permitted unprecedented levels of unsustainable resource extraction. The increasingly complex challenges human beings face in relation to the non-human world call for a paradigm shift: it is becoming ever more urgent to embrace new stories about ourselves and our relation to each other. This is the aim of ‘Stories on Earth’, Failed Architecture’s project for the parallel program of the Dutch Pavilion for the Venice Biennale 2021. Stories on Earth is an experiment which brings together spatial designers and writers to devise new spatial narratives that accommodate the inherent interrelationship between humans and the non-human. We selected three designers whose works challenge humans’ relationship with nature, and three writers with personal and professional connections with Caribbean storytelling…

Six designers and writers participating in FA’s project for Venice Biennale 2021 speak with one composite voice about nature, humanity, and storytelling at: “Stories on Earth: A Collective Voice for the Human and Non-Human.”

On this same topic, check in with musician and humanitarian Peter Gabriel, ecologist Carl Safina, technologist and novelist Jonathan Ledgard, prominent author and speaker on animal behaviour, Temple Grandin, and others…

We are pleased to announce the Interspecies Conversations Public Event 2020 in collaboration with the Coller Foundation, Google and MIT’s Center for Bits and Atoms. We would be delighted if you could join us and contribute to the conversation!

Interspecies I/O’s mission is to encourage, explore and facilitate interfaces for interspecies communication and approaches for deciphering the communication of non-human animals. With the aim to positively impact species conservation, welfare, empathy, compassion, enrichment, sustainability and understanding. It brings together a multidisciplinary group drawn from the sciences, arts and humanities in a rich collaborative forum, to advance the understanding and appreciation of the mental lives and intelligence of the diverse species with which we share our planet…

… at “Interspecies Conversations Public Conference 2020.”

And to complete the hat-trick, Matt Webb’s “On speaking with dolphins.”

As we “Talk to the Animals,” we might recall that it was on this date in 1983 that the first “test-tube baboon” was born; as The New York Times reported

A female black baboon, believed to be the first nonhuman primate conceived in a laboratory dish, has been born at the Southwest Foundation for Research and Education in San Antonio. The baby, named E. T., for embryo transfer, was born July 25, six months after its ”test-tube” fertilization and, coincidentally, on the fifth birthday of Louise Brown, the first human conceived ”in vitro.”…

“So profound is our ignorance, and so high our presumption, that we marvel when we hear of the extinction of an organic being”*…

A Neanderthal skull shows head trauma, evidence of ancient violence

 

Nine human species walked the Earth 300,000 years ago. Now there is just one. The Neanderthals, Homo neanderthalensis, were stocky hunters adapted to Europe’s cold steppes. The related Denisovans inhabited Asia, while the more primitive Homo erectus lived in Indonesia, and Homo rhodesiensis in central Africa.

Several short, small-brained species survived alongside them: Homo naledi in South Africa, Homo luzonensis in the Philippines, Homo floresiensis (“hobbits”) in Indonesia, and the mysterious Red Deer Cave People in China. Given how quickly we’re discovering new species, more are likely waiting to be found.

By 10,000 years ago, they were all gone. The disappearance of these other species resembles a mass extinction. But there’s no obvious environmental catastrophe – volcanic eruptions, climate change, asteroid impact – driving it. Instead, the extinctions’ timing suggests they were caused by the spread of a new species, evolving 260,000-350,000 years ago in Southern Africa: Homo sapiens.

The spread of modern humans out of Africa has caused a sixth mass extinction, a greater than 40,000-year event extending from the disappearance of Ice Age mammals to the destruction of rainforests by civilisation today. But were other humans the first casualties?…

More at “Were other humans the first victims of the sixth mass extinction?

As we wonder about our lost siblings, we might spare a thought for Marie Jean Pierre Flourens; he died on this date in 1867.  A physiologist, he was the founder of experimental brain science and a pioneer in anesthesia.  He was the first to demonstrate the general functions of the major portions of the vertebrate brain; more generally, through the study of ablations on vertebrate animals, he was the first to prove that the mind was located in the brain, not the heart (as was then believed).

Ironically, he was a Creationist– an opponent of Darwin and the theory of natural selection.

Scoping scale…

On AndaBien, web designer Steve Rose pursues his extra-vocational enthusiasms… among them, evolution.

His Evolution Timeline is a marvelous evocation of the sheer temporal scale of our antecedents.

— From first life-forms to homo sapiens

* The background indicates inches and feet.
* 1/20th in. = roughly 100 thousand years. (108,000)
* 1 inch = about 2 million years. (2,160,000)
* 1 foot = about 26 million years. (25,920,000)
* The whole page is about 135 feet wide, almost half a football field, representing 3.5 billion years. (3,500,000,000)

The very beginning of the timeline (and of life on Earth)

So, be prepared to scroll…  and scroll and scroll and scroll…  And to learn.  (By way of reinforcing one’s sense the extraordinary sweep of it all, readers might also appreciate Rose’s “Evolution, The Movie.”)

As we struggle with the recent revisions to the tree of life and the suggestion that humans are more closely related to fungus than to plants, we might recall that it was on this date in 1886 that Coca-Cola was first sold to the public at the soda fountain in Jacob’s Pharmacy in Atlanta, Georgia.  It was formulated by pharmacist John Stith Pemberton, who mixed it in a 30-gallon brass kettle hung over a backyard fire.  Pemberton’s recipe, which survived in use until 1905, was marketed as a “brain and nerve tonic,” and contained extracts of cocaine and (caffeine-rich) kola nut. The name, using two C’s from its ingredients, was suggested by his bookkeeper Frank Robinson, whose excellent penmanship provided the famous scripted  “Coca-Cola” logo.
