Extinction of the Species (Extinción de la especie) (2023) Matthew Porterfield and Nicolasa Ruiz

January 30th 2024

"During an archaeological dig in a desert area north of Jerusalem 40 years ago, a seed was discovered which was determined to be in pristine condition but had obviously seen many a year.

Now, despite falling from its parent 1,000 years ago, it has grown into a mature tree, and botanists examining it believe it may be an extinct species that was used for medicinal purposes for thousands of years—even receiving a nod in the Bible.

Neither Israeli botanists, nor Dr. Sarah Sallon, a physician who founded the Louis L. Borick Natural Medicine Research Center at Hadassah University Medical Center in Jerusalem, could determine what species it was from simply from the seed covering. So they did what nature intended—they planted it.

Using a well-documented technique that saw 2,000-year-old date palm fruit pits germinate, Dr. Sallon soaked the seed in hormones, liquid fertilizer, and water, and then planted it in a pot of sterile seed; then waited.

Despite its genetic code being exposed to environmental stressors for over 1,000 years, the seed sprouted after 5 weeks. The shoot was protected by a caplike feature called an operculum. As the shoot grew, the operculum was shed—leaving something for the team to radiocarbon date. It narrowed down the age of the almost 10-centuries-old seed to between the years 993 an 1202.

Fast forward 14 years and the plant has become a 10-foot-tall tree. Dr. Sallon shared images of the tree, its bark, and its leaves with botanists around the world. One expert suggested it belonged to the genus Commiphora, found across the Arabian Peninsula and parts of Africa. A genetic analysis subsequently revealed this was the case, but a perfect match was lacking.

Dr. Sallon and her team thought it was an extinct species known from history as Judean Balsam, but the best way to confirm that suspicion would be to have some aromatic traces similar to the resins of the myrrh tree to which it is related. However, no such fragrant compounds were detected.

Instead, the chemical analysis of the leaves identified a group of phytochemicals known as guggulterols which have been observed in a related species called Commiphora wightii that’s known to possess certain cancer-fighting properties in its resin.

A medicinal balm, the origin of which is not known, is mentioned in multiple historical texts including the Bible as ‘tsori,’ and rather than the fragrant Judean Balsam, it’s this tsori that Dr. Sallon and her team believe they have found.

They must wait until the tree, now 14 years old, produces flower or fruit to know for sure if it’s an extinct species, and if so, how to perhaps keep it alive.

Dr. Louise Colville, senior research leader in seed and stress biology at Royal Botanic Gardens, Kew, in London who wasn’t involved in the research, told CNN that it was a major accomplishment to grow a seed that old and possibly lead to a resurrection of this Biblical botanical.

“What’s surprising in this story is it was just a single seed and to be able to have one chance for that to germinate is extremely lucky,” she said.

“Working in a seed bank, seeing the potential for that extreme longevity gives us hope that banking and storing seeds that some at least will survive for very long periods of time.”"

Note: This is such a good demonstration of why seed banks are so important!! They give us such real and massive hope for deextinction and the revival of endangered species.

i hate talking to people who aren’t aware of or just don’t care how disastrous climate change is. i say “summer is lasting too long” and they go “but i like the warm weather! :)” 😐

A study that just came out demonstrates that outdoor cats are known to prey on over two thousands species of wild animal, from mammals to birds to insects. That includes 347 species that are endangered, threatened or otherwise of concern, and they've been a key factor of the permanent extinction of over 60 species. And while cats may not always bring home what they catch, chances are if your cat is allowed to roam unsupervised outside, they're killing your local wildlife.

Why is this so important? Worldwide, wild animal populations have decreased in number by 69% in the past fifty years; that means that in my lifetime (born in 1978), the sheer number of wild animals in the world has been decreased by over half. Even "common" wild species are less numerous than before. While habitat population is the single biggest cause of species endangerment and extinction overall, outdoor and indoor/outdoor cats are a significant cause as well. In fact, they are the single biggest cause of human-caused mortality in wild birds.

Most importantly, it's very, very simple to fix this problem: keep your cats indoors, and spay and neuter them. If your cat is bored, they need more enrichment, and there are plenty of ways to make your home more exciting for them, from bringing home cardboard boxes for them to explore, to playing with them more often. If you want your cat to get some outdoor enrichment, leash train them (yes, it can be done!) If you have the space and resources, build them a catio where they can be safe from outdoor dangers like predators and cars, while also keeping local wildlife safe from them.

If you just give into their whining and pawing at the door, then they know that that's what they have to do to get their way; I know it's a tough transition, but it's worth it in the end for everyone involved. Cats are domesticated, which means they are not native anywhere in the world; there are exactly zero ecosystems in which they belong, save for the safety of your home. It is your responsibility to give them an enriching environment without taking the shortcut of letting them go wreak havoc outside.

text from porter robinson's "goodbye to a world"

every single animal in this comic is extinct. it's not too late for the ones that are left.

edit: thanks @mudcrabmassacre for the correction, smilodon fatalis did not in fact go extinct in 1023 AD. the actual prediction is around 10,000 years ago - I think i may have missed a zero or two.

by the way if you think an endangered species deserves to go extinct because it takes effort to save them/they can’t look after themselves, you need to reevaluate the way you look at the world because that is an extremely flawed, messed up, and sad worldview.

1. Four new cheetah cubs born in Saudi Arabia after 40 years of extinction

“[T]he discovery of mummified cheetahs in caves […] which ranged in age from 4,000 to as recent as 120 years, proved that the animals […] once called [Saudi Arabia] home. The realisation kick-started the country’s Cheetah Conservation Program to bring back the cats to their historic Arabian range. […] Dr Mohammed Qurban, CEO of the NCW, said: […] “This motivates us to continue our efforts to restore and reintroduce cheetahs, guided by an integrated strategy designed in accordance with best international practices.””

2. In sub-Saharan Africa, ‘forgotten’ foods could boost climate resilience, nutrition

“[A study published in PNAS] examined “forgotten” crops that may help make sub-Saharan food systems more resilient, and more nutritious, as climate change makes it harder to grow [current staple crops.] [… The study identified 138 indigenous] food crops that were “relatively underresearched, underutilized, or underpromoted in an African context,” but which have the nutrient content and growing stability to support healthy diets and local economies in the region. […] In Eswatini, van Zonneveld and the World Vegetable Center are working with schools to introduce hardy, underutilized vegetables to their gardens, which have typically only grown beans and maize.”

3. Here's how $4 billion in government money is being spent to reduce climate pollution

“[New Orleans was awarded] nearly $50 million to help pay for installing solar on low to middle income homes [… and] plans to green up underserved areas with trees and build out its lackluster bike lane system to provide an alternative to cars. […] In Utah, $75 million will fund several measures from expanding electric vehicles to reducing methane emissions from oil and gas production. [… A] coalition of states led by North Carolina will look to store carbon in lands used for agriculture as well as natural places like wetlands, with more than $400 million. [… This funding is] “providing investments in communities, new jobs, cost savings for everyday Americans, improved air quality, … better health outcomes.””

4. From doom scrolling to hope scrolling: this week’s big Democratic vibe shift

“[Democrats] have been on an emotional rollercoaster for the past few weeks: from grim determination as Biden fought to hang on to his push for a second term, to outright exuberance after he stepped aside and Harris launched her campaign. […] In less than a week, the Harris campaign raised record-breaking sums and signed up more than 100,000 new volunteers[….] This honeymoon phase will end, said Democratic strategist Guy Cecil, warning the election will be a close race, despite this newfound exuberance in his party. [… But v]oters are saying they are excited to vote for Harris and not just against Trump. That’s new.”

5. Biodegradable luminescent polymers show promise for reducing electronic waste

“[A team of scientists discovered that a certain] chemical enables the recycling of [luminescent polymers] while maintaining high light-emitting functions. […] At the end of life, this new polymer can be degraded under either mild acidic conditions (near the pH of stomach acid) or relatively low heat treatment (> 410 F). The resulting materials can be isolated and remade into new materials for future applications. […] The researchers predict this new polymer can be applied to existing technologies, such as displays and medical imaging, and enable new applications […] such as cell phones and computer screens with continued testing.”

6. World’s Biggest Dam Removal Project to Open 420 Miles of Salmon Habitat this Fall

“Reconnecting the river will help salmon and steelhead populations survive a warming climate and [natural disasters….] In the long term, dam removal will significantly improve water quality in the Klamath. “Algae problems in the reservoirs behind the dams were so bad that the water was dangerous for contact […] and not drinkable,” says Fluvial Geomorphologist Brian Cluer. [… The project] will begin to reverse decades of habitat degradation, allow threatened salmon species to be resilient in the face of climate change, and restore tribal connections to their traditional food source.”

7. Biden-Harris Administration Awards $45.1 Million to Expand Mental Health and Substance Use Services Across the Lifespan

““Be it fostering wellness in young people, caring for the unhoused, facilitating treatment and more, this funding directly supports the needs of our neighbors,” said HHS Secretary Xavier Becerra. [The funding also supports] recovery and reentry services to adults in the criminal justice system who have a substance use disorder[… and clinics which] serve anyone who asks for help for mental health or substance use, regardless of their ability to pay.”

8. The World’s Rarest Crow Will Soon Fly Free on Maui

“[… In] the latest attempt to establish a wild crow population, biologists will investigate if this species can thrive on Maui, an island where it may have never lived before. Translocations outside of a species’ known historical range are rare in conservation work, but for a bird on the brink of extinction, it’s a necessary experiment: Scientists believe the crows will be safer from predators in a new locale—a main reason that past reintroduction attempts failed. […] As the release date approaches, the crows have already undergone extensive preparation for life in the wild. […] “We try to give them the respect that you would give if you were caring for someone’s elder.””

9. An optimist’s guide to the EV battery mining challenge

““Battery minerals have a tremendous benefit over oil, and that’s that you can reuse them.” [… T]he report’s authors found there’s evidence to suggest that [improvements in technology] and recycling have already helped limit demand for battery minerals in spite of this rapid growth — and that further improvements can reduce it even more. [… They] envision a scenario in which new mining for battery materials can basically stop by 2050, as battery recycling meets demand. In this fully realized circular battery economy, the world must extract a total of 125 million tons of battery minerals — a sum that, while hefty, is actually 17 times smaller than the oil currently harvested every year to fuel road transport.”

10. Peekaboo! A baby tree kangaroo debuts at the Bronx Zoo

“The tiny Matschie’s tree kangaroo […] was the third of its kind born at the Bronx Zoo since 2008. [… A] Bronx Zoo spokesperson said that the kangaroo's birth was significant for the network of zoos that aims to preserve genetic diversity among endangered animals. "It's a small population and because of that births are not very common," said Jessica Moody, curator of primates and small mammals at the Bronx Zoo[, …] adding that baby tree kangaroos are “possibly one of the cutest animals to have ever lived. They look like stuffed animals, it's amazing.””
