Public Darwin vs. his evil doppelganger?

Rescuing Evolution from Darwinian Myth


Does the public promotion of Darwin’s theory of natural selection match Darwin’s own private view of his theory? On a classic episode of ID the Future, historian of science Michael Keas begins a two-part conversation with Robert Shedinger, the Wilford A. Johnson Chair of Biblical Studies and Professor of Religion at Luther College. Shedinger, author of Darwin’s Bluff, reports on the contrast between Darwin’s private view of his theory of natural selection and the public view as detailed in his published work. Shedinger also notes the deficiency in evidence for Darwin’s proposal, despite claims to the contrary from his followers and evangelizers today.

On musing on JEHOVAH’S inventions rather than man's

 Why John Muir Chose Nature Over Machines


John Muir (1838 – 1914) is typically remembered as one of America’s foremost naturalists, father of the country’s national parks, and tireless defender of the wilderness. But he might very well have been none of those things. As a young man, Muir was gifted at building machines, and he was set to pursue a career in technology until everything went dark. Literally. Revisiting this little-known chapter of Muir’s life can inspire us to better navigate our own relationship to technology and give us a fresh reason to celebrate his work.

In 1849, Muir left his homeland of Scotland and moved with his family to the backwoods of Wisconsin. Farm work, chores, and family Bible studies kept him busy most waking hours, and he often sacrificed sleep to read and build. The family cellar became his workshop, where he fashioned a host of time-saving inventions, including clocks, barometers, sawmills, and lamplighters. He even conjured up an “early-rising machine,” a bed connected to a clock that tilted the sleeper out of bed and into a pail of cold water at the desired hour each day. 

Though his mother hoped he would become a minister, his sisters and friends saw in Muir the makings of a great inventor. Hoping his inventions might lead to a career as a physician, Muir left home in his early 20s to continue his education and “live a while among machines.” At the Wisconsin State Fair in Madison, his novel contraptions drew praise from spectators and journalists alike, opening doors to employment and further instruction. In college, he continued to indulge his love of creating mechanical devices, including a fire-starting machine and a student desk that automatically dispensed and opened textbooks at desired intervals. At the same time, lessons in botany stoked in Muir a growing passion for nature. 

Two Great Loves

In 1866, Muir took a job at a carriage manufactory in Indianapolis. His work as a machinist prompted his boss to offer him higher wages and the position of foreman. Muir later recalled in his autobiography the difficulty of choosing between two great loves: “I liked the work of inventing and enjoyed the rush and roar and whirl of so many machines — it was a place, that factory, according to my own heart — but the attractions of nature were stronger, and I must sometime get away.”

The following year, while repairing a machine belt at work, the sharp end of a file pierced Muir’s right eye, temporarily blinding him in both eyes. He was confined to bed and a dark room for several weeks. Fearful he might never regain his sight, Muir was comforted during his recovery by visitors reading to him and by correspondence from loved ones. One such letter from his lifelong friend and mentor Jeanne Carr encouraged Muir to be patient and hopeful: “I have often in my heart wondered what God was training you for. He gave you the eye within the eye, to see in all natural objects the realized ideas of His mind…He will surely place you where your work is.”

A Mind for Nature


The Muir who emerged from the dark room was more anxious to travel than ever, determined to fill his mind with as much natural beauty as he could before another accident could stop him. As he put it years later in The Story of My Boyhood and Youth: “I made haste with all my heart, bade adieu to all thoughts of inventing machinery and determined to devote the rest of my life to studying the inventions of God.” 

With thoughts of California’s Yosemite Valley already swirling in his mind from brochures he had read, Muir decided to first satisfy a long-held desire to traverse the wilds of the American South. In the fall of 1867, he embarked on a thousand-mile walk to the Gulf. Facing unfamiliar territory with a renewed sense of purpose and urgency, Muir wrote in a letter a few days before his journey that he would be “carried of the Spirit into the wilderness.” With this excursion, the Muir many of us recognize today begins to take shape.

Though Muir committed himself to spending the rest of his life studying nature, he did not discard his mechanical inclinations overnight. In the winter of 1869, he built a sawmill for James Hutchings, the Yosemite Valley’s first permanent resident. A few years later, he asked one of his brothers to send a trunk full of his tools and models to him. While he lived in the Sierra Nevada mountains, he continued to use his own clocks to keep time and his singular alarm clock bed to get him up each morning. Even in the wilderness, Muir did not abandon human invention. He continued to use it as a tool. 

Exhilarating and Bewildering


Today, we live in a technological age that is by turns exhilarating and bewildering. As we navigate the challenges of AI, social media, and smartphone use, we need the benefits nature can give us now more than ever. Muir was passionate about machines, but he was willing to put them aside for the healing, perspective, and inspiration he found in the wilderness. Can we look up from our screens long enough to do the same? Here are two ways we can follow Muir’s lead.

First, get a bigger dose of wild. Muir could hardly contain himself in his praise of nature’s bounty: “Every landscape…and every one of its living creatures…and every crystal of its rocks…is throbbing and pulsing with the heartbeats of God.” All right for him, you might think, but what about us? According to a recent survey, most of us spend free time in nature at least once a month. But that may not be enough. A 2019 study reported that at least two hours a week in natural environments was associated with better health and wellbeing. That means a whole host of advantages, from reducing inflammation and mental distress to boosting cognitive function, improving sleep, and even protecting our vision. 

A walk in the woods might provide an optimal dose of nature, but any natural setting that includes greenery, fresh air, and sunlight will serve. Build into your weekly calendar a few forays into natural spaces. And every now and then, take your shoes and socks off and walk barefoot in the grass. This conductive contact between our body and the surface of the earth is known as grounding or earthing. It has a positive effect on our physiology and health, reducing inflammation and helping with pain relief and wound healing. You don’t have to sell all your stuff and go live off-grid to tap into the benefits of nature, but you will have to be purposeful. The good news is that you’ll start to feel results as soon as you make the effort. 

A second way to follow Muir’s example is by nurturing your inner life. We are endowed with the formidable power of our intellect, but these days, we’re living more reflexively than reflectively. We’re avoiding the activity of just thinking because we consider it a waste of time. A recent study in the Journal of Experimental Psychology compared expectations of thinking with the actual experience of doing it. Across the board, participants reported greater interest and engagement than they had anticipated beforehand. 

A Reservoir of Meaning

Each type of thinking we do provides its own mental benefits. For example, daydreaming is our uniquely human ability to alternate between fantasy and reality. It’s a force that can inspire change and make life more bearable at any age. Mind wandering, or “stream of consciousness thought,” allows us to generate novel, creative thoughts and gives us a space to consider obstacles to our goals. Even nostalgic thinking, often considered detrimental, can provide us with a reservoir of meaning and give us a sense of continuity between our present and our past. Boost your clarity and motivation by working up to at least twenty minutes a day of thinking without distraction.   

If Muir were still with us, he’d no doubt be intensely intrigued by our modern technological society. We’ve come a long way. And yet, for all our advancement, we still need what was here all along. And we need people like John Muir to remind us.

Braver and newer than ever

 

Neanderthals just keep getting more "Sapien"

 Neanderthals Keep Getting Smarter


Contemplate this headline: “Archaeologists Find Neanderthal Stone Tool Technology in China.”

At one time, Neanderthals were considered stupid. So the implication would be that those tools didn’t work very well.

Things have changed. Neanderthal art, glue, ornaments, etc., have forced a rethink. Those who are looking for the subhuman are still looking…

Those Mysterious Neanderthals

Meanwhile, Neanderthals are presenting some mysteries, including this one:

At ZME Science, Alexandra Gerea reports that stone tools found in Yunnan province in China, dating from 50,000 to 60,000 years ago, “look exactly like those made by Neanderthals in Ice Age Europe” using a technique now called Quina:

For a long time, archaeologists thought people in East Asia completely skipped the Middle Paleolithic. But this discovery says otherwise.

Quina is not just a vague style. It’s a craftsmanship signature. These tools — thick, sharp-edged scrapers with repeated retouch marks — were long considered an unmistakable calling card of Neanderthals in Europe.

Their presence in East Asia is perplexing. They’re around 7 to 8 thousand kilometers east of the region traditionally associated with this technology. 

“Neanderthal Stone Tool Technology,” April 4, 2025

From the paper’s Abstract

The finding of a Quina lithic assemblage in China not only demonstrates the existence of a Middle Paleolithic technology in the region but also shows large-scale analogies with Neanderthal behaviors in western Europe. Longtan substantially extends the geographic distribution of this technical behavior in East Asia. Although its origin remains unclear, implications for Pleistocene hominin dispersal and adaptation to diverse ecological settings are considered. 

Q. Ruan et al., Quina lithic technology indicates diverse Late Pleistocene human dynamics in East Asia, Proc. Natl. Acad. Sci. U.S.A. 122 (14) e2418029122, https://doi.org/10.1073/pnas.2418029122 (2025)

Could these far-separated populations have met up?

Fifty Years of Progress

Study author Ben Marwick doesn’t speculate on that at The Conversation, but he does say,

During the Middle Paleolithic, there were multiple human species that could make tools like this. It could have been modern humans like us. But it could also have been Neanderthals. Considering that the Quina technology in Europe is directly associated with Neanderthals, this seems likely. But it could also have been Denisovans, an extinct species similar to modern humans found during this time in Siberia, the Tibetan Plateau and Laos, or even a new human species that hasn’t been seen before.

Whoever was making and using these Quina scrapers, they were able to be inventive and flexible with their technology, adapting to their changing environment.

“Stone tool discovery in China shows people in East Asia were innovating during the Middle Paleolithic, like in Europe and Middle East,” March 31, 2025

Neanderthal man has sure smartened up in the last fifty years.

The rise and fall of the mongol horde.
