I am saddened by the announcement from U.S. Fish and Wildlife that confirms the extinction of Stephan’s riffle beetle (Heterelmis stephani) from Arizona, and the Tatum Cave beetle (Pseudanophthalmus parvus) from Kentucky.
This will not be front page news. These are not charismatic species and they’re not widely known. This announcement will not generate widespread attention. I predict it may not be picked up by popular media at all - I learned the news from a tweet by Derek Hennen’s (@entoderek), and he’s an entomologist deeply interested in these topics.
Those reasons ^ are partly why I am upset, because I see the lack of attention as indication that people were never given a reason to care in the first place. I did not know of either species until learning, too late, that they are gone.
But another reason I’m upset is because the dwindling numbers of each population did not happen overnight. According to the announcement, Stephan’s riffle beetle was identified as needing protection under the Endangered Species Act 32 years ago, in 1984. Tatum’s cave beetle was similarly recognized ten years later, in 1994.
We’ve done a video on the Endangered Species Act, and with that episode we highlighted some of the challenges and roadblocks in place when it comes to receiving governmental protection. The ESA has done a lot of good… but it’s nowhere near perfect. Because of our inability to act nimbly and responsively, these species, and the ecosystems in which they played any number of roles, suffer.
With announcements such as this - with the knowledge we’ve lost a little more, and are poorer in diversity - I wonder, what can I do? How can I help? What options do we give other people to help? I’ll never have a comprehensive answer, but I will keep generating small answers, sharing ideas and resources, and continue to promote lifelong learning and curiosity. Maybe along the way, we’ll catch the eye of someone interested in helping us fix some of these systems.
From 1956 to 1996, the Mormon Church operated a program where Native American kids were baptized and placed in Mormon foster homes during the school year. The idea was fostering would “lighten” them. The Mormon Church teaches that Native Americans were originally white, but God punished them, and made them darker.
It began being criticized in the 1970s for weakening the children’s connection to their Native American families and communities, and causing psychological damage. And today the Mormon Church is being sued in tribal court for allegations of abuse while in their foster homes.
Amazingly, we have a photograph of a man who crossed the Delaware with George Washington. This is Conrad Heyer, born in 1749 and photographed in 1852 at age 103. He served in the Continental Army during the Revolutionary War, crossed the Delaware with Washington in December 1776, and fought in several major battles. The Maine Historical Society says that this makes him the earliest-born human being ever to be photographed.

As we prepare for more cold weather this weekend, let’s take a look back at Sir Ernest Shackleton’s 1914 voyage to the Antarctic. Just one day’s sail from the continent, his ship Endurance became trapped in sea ice. Frozen fast for 10 months, the ship was crushed and destroyed by ice pressure, and the crew was forced to abandon it. After camping on the ice for five months, Shackleton made two open boat journeys, one of which—a treacherous 800-mile ocean crossing to South Georgia Island—is now considered one of the greatest boat journeys in history. Trekking across the mountains of South Georgia, Shackleton reached the island’s remote whaling station, organized a rescue team, and saved all of the men he had left behind.

The “dinosaur bones” that you see on display at the Museum aren’t really bones at all. Through the process of fossilization, ancient animal bones are turned into rock.
Most ancient animals never became fossils. Their carcasses were likely consumed by other organisms, or worn away by wind or water. But sometimes the conditions were right and their remains were preserved. The most common process of fossilization happens when an animal is buried by sediment, such as sand or silt, shortly after it dies. Its bones are protected from rotting by layers of sediment. As its body decomposes all the fleshy parts wear away and only the hard parts, like bones, teeth, and horns, are left behind. Over millions of years, water in the nearby rocks surrounds these hard parts, and minerals in the water replace them, bit by bit. When the minerals have completely replaced the organic tissue, what’s left is a solid rock copy of the original specimen.
