I meet many people offended by evolution, who passionately prefer to be the personal handicraft of God than to arise by blind physical and chemical forces over aeons from slime…What they wish to be true, they believe is true.

Only 9 percent of Americans accept the central finding of modern biology that human beings (and all other species) have slowly evolved by natural processes from a succession of more ancient beings with no divine intervention needed along the way.

How Mysterious Natural Arches Form

Arches of stone seem to defy explanation, but a new study may have solved the mystery of how these and other strange natural stone wonders form.

The bewildering shapes apparently owe their origin in large part to how rock can strengthen when squashed from above, scientists explained.

Mysterious rock formations such as arches, bridges, pillars and mushroom-shaped pedestal rocks occur all over the world. Geologists mostly think these form due to erosion from wind and water, as well as from the weathering effects of salt and frost.

However, lead author of the new study Jiří Bruthans, a geologist at Charles University in Prague, and his colleagues did not think erosion and weathering alone could explain how many of these natural sculptures arose. They also noted that prior research did not explain how the upper parts of arches remain stable.

Now, the researchers said they can help explain how these rock formations develop by accounting for the way rock can strengthen when compacted by weight from above.

"The results were shocking for me when I started to realize how simply nature carves all these shapes," Bruthans said.

photos by gerry ellis from the david sheldrick wildlife trust, a nursery and orphanage for elephants in kenya’s tsavo east national park. here, fifty five keepers are charged with being around the clock parents to an elephant. the elephants, however, are the ones who chose their caretakers; it is the keepers who must ingratiate themselves to the elephants and earn their trust.

when elephants first arrive at the orphanage they are often traumatized from having witnessed the slaughter of their mothers and family by poachers. grieving can last several months, and they often lose the will to live. but as dame daphne sheldrick, founder of the orphanage, explains, a caretaker is charged with “persuading an elephant to live when it wants to die.”

approximately 35,000 elephants are killed by humans every year. with an estimated 350,000 elephants left in the whole continent of africa, they will be gone in the wild within ten years.

cbc’s the nature of things did a program on the elephants and their caretakers. you can foster an elephant with the david sheldrick wildlife trust online here. for more on the emotional lives of elephants, as well as the david sheldrick wildlife trust and other human efforts to save them, check out these posts
