Your Beloved Pet Is Old. Should You Clone It?
Melvin was a special dog. A mixture of Catahoula and Doberman with black and tan markings, he was the office greeter, barking hellos to everyone who visited the Dupont Veterinary Clinic in Lafayette, Louisiana, which is owned by his human companions, Dr. Phillip Dupont and his wife, Paula. The couple say he's the best dog they ever owned.
When Melvin passed away, having two identical replicas helped ease the couple's grief.
He seemed to have an uncanny knack for understanding what they were saying, he could find lost car keys in tall grasses and the Duponts trusted him so much they felt comfortable having him babysit their grandson unattended in the backyard.
So when the 75-pound canine turned 9 and began to show signs of age, the Duponts sent off some of his skin cells to a lab in South Korea, the Sooam Biotech Research Foundation, to have him cloned. The Duponts toured the South Korean facilities and were satisfied that the animals were being treated well. While the first cloned puppy died from distemper, the second attempt produced two healthy animals—which the couple named Ken and Henry. When Melvin did pass away nearly two years later, in 2014, having two identical replicas helped ease the couple's grief. Even though it cost about $70,000 to clone Melvin, it was well worth it. "Melvin gave us a lot of pleasure," says Paula Dupont, "and this was less than the price of a new Land Cruiser."
As the technology improves, costs will tumble, making pet cloning more affordable for the mainstream.
The news has been filled recently with stories of celebrities such as Barbra Streisand or billionaire Barry Diller and his fashion icon wife, Diane von Furstenberg, spending big bucks to preserve their beloved pets—a practice New York magazine called "a laughable, extravagant waste of money." But cloning Fido isn't just for the ultra-wealthy anymore. Texas-based ViaGen now offers a domestic cloning service that will replicate Lassie for $50,000 and Garfield's kittens for a mere $25,000. While the exact number of cloned pets isn't known, the South Korean company says it has cloned about 800 pets while ViaGen has cloned about 100 cats and dogs. And as the technology improves, costs will tumble, making it more affordable for the mainstream, says Ron Gillespie, who heads PerPETuate, a Massachusetts-based outfit that collects and cryo preserves pet DNA, and works closely with ViaGen.
Even if the animals are genetic twins, biologists say, there are no guarantees their personalities will match, too.
While replicating Fido is becoming more feasible, should you? Animal rights organizations like The Humane Society and PETA are sharply critical of the practice, which is largely unregulated, and think it's outrageous to spend $50,000 or more to preserve Fluffy's genetic makeup when millions of cats and dogs are languishing in shelters and millions more are euthanized every year. And even if the animals are genetic twins, biologists say, there are no guarantees their personalities will match, too. Like humans, dogs' personalities are influenced by their environment and there are always variations in how the genes are expressed--although the Duponts say that Ken and Henry seem more like Melvin every day. "Their personalities are identical," says Paula.
Clones Ken and Henry, with Dr. Dupont and 10-year-old Melvin. Though all three dogs are genetic twins, their markings differ because the environment can influence how genes are expressed.
Still, the loss of a beloved pet can be incredibly painful, and in some cases, cloning can help deal with deep psychological wounds. When Monni Must's daughter died suddenly at age 28, the Michigan-based photographer adopted her child's black Lab, Billy Bean. As the dog got older and frailer, Must realized she couldn't handle losing her last link to her daughter—so she ponied up $50,000 to have the animal cloned. "I knew that I was falling apart," Must told Agence France-Presse. "The thought of Billy dying was just more than I could handle."
But these heated disputes miss what bioethicists believe is the real ethical dilemma—the fate of the female animals that provide the eggs and gestate the cloned puppies. "This issue tends to get framed as 'it's their personal choice, it's their money and they can do what they want with it,'" says Jessica Pierce, a bioethicist and author of Run, Spot, Run: The Ethics of Keeping Pets. "But this whole enterprise has all this collateral damage and behind-the-scenes impacts that people ignore. No one is talking about the dogs who are sacrificing themselves for this indulgence, and are suffering and being tormented just to have your clone."
"Even in the best-case scenarios, the cloned pet may go through several rounds of failed reproductive attempts—failed pregnancies, still births, and deformities."
Animal cloning, of course, is not new. Dolly, the sheep, made her debut in 1996 as the first cloned mammal. In 2005, Korea's Sooam Biotech cloned the first dog, and cloning horses and cows has become almost routine. Typically, the cloning process for dogs is fairly uncomplicated. It entails the use of a group of female dogs whose hormones are artificially manipulated with drugs to promote them to produce eggs. The eggs are then surgically harvested from donor dogs' ovaries. The immature eggs are stripped of their genetic information and then the pet's DNA is fused with the egg. When the embryo begins to develop, it is then transplanted to the womb of a surrogate dog.
However, cloning can have a high failure rate. When South Korea's Sooam Biotech lab cloned the first dog in 2005, there were 1000 failures—which means that number of eggs were fertilized and began to gestate, but at some point their development failed. And this figure doesn't include the number of dogs born with deformities serious enough that they are incompatible with life and need to be euthanized. "Even in the best-case scenarios, the cloned pet may go through several rounds of failed reproductive attempts—failed pregnancies, still births, and deformities," says Insoo Hyun, a bioethicist at Case Western Reserve University in Cleveland. "You can't do just one egg and one transfer. That won't happen. There is no guarantee that the very first time you will have a healthy animal. They're not miracle workers and you can't fight biology."
"You just have to let your pet go. It's all part of the experience."
But Ron Gillespie, who's been in the animal breeding business for decades, thinks these fears are overblown and that cloning is similar to the selective breeding that goes on all the time with cattle and even with champion racehorses. "We're really the victim of a lot of misinformation and misunderstanding," he says. "Right now, on average, we're dealing with three dogs: two that supply eggs and one to carry the embryo to term."
Still, this debate skirts the hard realities: dogs and cats simply have shorter lifespans than humans, and ethicists and animal rights activists believe there are better ways to deal with that grief. "You just have to let your pet go," says Hyun. "It's all part of the experience."
Genome Reading and Editing Tools for All
In 2006, the cover of Scientific American was "Know Your DNA" and the inside story was "Genomes for All." Today, we are closer to that goal than ever. Making it affordable for everyone to understand and change their DNA will fundamentally alter how we manage diseases, how we conduct clinical research, and even how we select a mate.
A frequent line of questions on the topic of making genome reading affordable is: Do we need to read the whole genome in order to accurately predict disease risk?
Since 2006, we have driven the cost of reading a human genome down from $3 billion to $600. To aid interpretation and research to produce new diagnostics and therapeutics, my research team at Harvard initiated the Personal Genome Project and later, Openhumans.org. This has demonstrated international informed consent for human genomes, and diverse environmental and trait data can be distributed freely. This is done with no strings attached in a manner analogous to Wikipedia. Cell lines from that project are similarly freely available for experiments on synthetic biology, gene therapy and human developmental biology. DNA from those cells have been chosen by the US National Institute of Standards and Technology and the Food and Drug Administration to be the key federal standards for the human genome.
A frequent line of questions on the topic of making genome reading affordable is: Do we need to read the whole genome in order to accurately predict disease risk? Can we just do most commonly varying parts of the genome, which constitute only a tiny fraction of a percent? Or just the most important parts encoding the proteins or 'exome,' which constitute about one percent of the genome? The commonly varying parts of the genome are poor predictors of serious genetic diseases and the exomes don't detect DNA rearrangements which often wipe out gene function when they occur in non-coding regions within genes. Since the cost of the exome is not one percent of the whole genome cost, but nearly identical ($600), missing an impactful category of mutants is really not worth it. So the answer is yes, we should read the whole genome to glean comprehensively meaningful information.
In parallel to the reading revolution, we have dropped the price of DNA synthesis by a similar million-fold and made genome editing tools close to free.
WRITING
In parallel to the reading revolution, we have dropped the price of DNA synthesis by a similar million-fold and made genome editing tools like CRISPR, TALE and MAGE close to free by distributing them through the non-profit Addgene.org. Gene therapies are already curing blindness in children and cancer in adults, and hopefully soon infectious diseases and hemoglobin diseases like sickle cell anemia. Nevertheless, gene therapies are (so far) the most expensive class of drugs in history (about $1 million dollars per dose).
This is in large part because the costs of proving safety and efficacy in a randomized clinical trial are high and that cost is spread out only over the people that benefit (aka the denominator). Striking growth is evident in such expensive hyper-personalized therapies ever since the "Orphan Drug Act of 1983." For the most common disease, aging (which kills 90 percent of people in wealthy regions of the world), the denominator is maximal and the cost of the drugs should be low as genetic interventions to combat aging become available in the next ten years. But what can we do about rarer diseases with cheap access to genome reading and editing tools? Try to prevent them in the first place.
A huge fraction of these births is preventable if unaffected carriers of such diseases do not mate.
ARITHMETIC
While the cost of reading has plummeted, the value of knowing your genome is higher than ever. About 5 percent of births result in extreme medical trauma over a person's lifetime due to rare genetic diseases. Even without gene therapy, these cost the family and society more than a million dollars in drugs, diagnostics and instruments, extra general care, loss of income for the affected individual and other family members, plus pain and anxiety of the "medical odyssey" often via dozens of mystified physicians. A huge fraction of these births is preventable if unaffected carriers of such diseases do not mate.
The non-profit genetic screening organization, Dor Yeshorim (established in 1983), has shown that this is feasible by testing for Tay–Sachs disease, Familial dysautonomia, Cystic fibrosis, Canavan disease, Glycogen storage disease (type 1), Fanconi anemia (type C), Bloom syndrome, Niemann–Pick disease, Mucolipidosis type IV. This is often done at the pre-marital, matchmaking phase, which can reduce the frequency of natural or induced abortions. Such matchmaking can be done in such a way that no one knows the carrier status of any individual in the system. In addition to those nine tests, many additional diseases can be picked up by whole genome sequencing. No person can know in advance that they are exempt from these risks.
Furthermore, concerns about rare "false positives" is far less at the stage of matchmaking than at the stage of prenatal testing, since the latter could involve termination of a healthy fetus, while the former just means that you restrict your dating to 90 percent of the population. In order to scale this up from 13 million Ashkenazim and Sephardim to billions in diverse cultures, we will likely see new computer security, encryption, blockchain and matchmaking tools.
Once the diseases are eradicated from our population, the interventions can be said to impact not only the current population, but all subsequent generations.
THE FUTURE
As reading and writing become exponentially more affordable and reliable, we can tackle equitable distribution, but there remain issues of education and security. Society, broadly (insurers, health care providers, governments) should be able to see a roughly 12-fold return on their investment of $1800 per person ($600 each for raw data, interpretation and incentivizing the participant) by saving $1 million per diseased child per 20 families. Everyone will have free access to their genome information and software to guide their choices in precision medicines, mates and participation in biomedical research studies.
In terms of writing and editing, if delivery efficiency and accuracy keep improving, then pill or aerosol formulations of gene therapies -- even non-prescription, veterinary or home-made versions -- are not inconceivable. Preventions tends to be more affordable and more humane than cures. If gene therapies provide prevention of diseases of aging, cancer and cognitive decline, they might be considered "enhancement," but not necessarily more remarkable than past preventative strategies, like vaccines against HPV-cancer, smallpox and polio. Whether we're overcoming an internal genetic flaw or an external infectious disease, the purpose is the same: to minimize human suffering. Once the diseases are eradicated from our population, the interventions can be said to impact not only the current population, but all subsequent generations. This reminds us that we need to listen carefully, educate each other and proactively imagine and deflect likely, and even unlikely, unintended consequences, including stigmatization of the last few unprotected individuals.
The rise of remote work is a win-win for people with disabilities and employers
Disability advocates see remote work as a silver lining of the pandemic, a win-win for adults with disabilities and the business world alike.
Any corporate leader would jump at the opportunity to increase their talent pool of potential employees by 15 percent, with all these new hires belonging to an underrepresented minority. That’s especially true given tight labor markets and CEO desires to increase headcount. Yet, too few leaders realize that people with disabilities are the largest minority group in this country, numbering 50 million.
Some executives may dread the extra investments in accommodating people’s disabilities. Yet, providing full-time remote work could suffice, according to a new study by the Economic Innovation Group think tank. The authors found that the employment rate for people with disabilities did not simply reach the pre-pandemic level by mid-2022, but far surpassed it, to the highest rate in over a decade. “Remote work and a strong labor market are helping [individuals with disabilities] find work,” said Adam Ozimek, who led the research and is chief economist at the Economic Innovation Group.
Disability advocates see this development as a silver lining of the pandemic, a win-win for adults with disabilities and the business world alike. For decades before the pandemic, employers had refused requests from workers with disabilities to work remotely, according to Thomas Foley, executive director of the National Disability Institute. During the pandemic, "we all realized that...many of us could work remotely,” Foley says. “[T]hat was disproportionately positive for people with disabilities."
Charles-Edouard Catherine, director of corporate and government relations for the National Organization on Disability, said that remote-work options had been advocated for many years to accommodate disabilities. “It’s a little frustrating that for decades corporate America was saying it’s too complicated, we’ll lose productivity, and now suddenly it’s like, sure, let’s do it.”
The pandemic opened doors for people with disabilities
Early in the pandemic, employment rates dropped for everyone, including people with disabilities, according to Ozimek’s research. However, these rates recovered quickly. In the second quarter of 2022, people with disabilities aged 25 to 54, the prime working age, are 3.5 percent more likely to be employed, compared to before the pandemic.
What about people without disabilites? They are still 1.1 percent less likely to be employed.
These numbers suggest that remote work has enabled a substantial number of people with disabilities to find and retain employment.
“We have a last-in, first-out labor market, and [people with disabilities] are often among the last in and the first out,” Ozimek says. However, this dynamic has changed, with adults with disabilities seeing employment rates recover much faster. Now, the question is whether the new trend will endure, Ozimek adds. “And my conclusion is that not only is it a permanent thing, but it’s going to improve.”
Gene Boes, president and chief executive of the Northwest Center, a Seattle organization that helps people with disabilities become more independent, confirms this finding. “The new world we live in has opened the door a little bit more…because there’s just more demand for labor.”
Long COVID disabilities put a premium on remote work
Remote work can help mitigate the impact of long COVID. The U.S. Centers for Disease Control and Prevention reports that about 19 percent of those who had COVID developed long COVID. Recent Census Bureau data indicates that 16 million working age Americans suffer from it, with economic costs estimated at $3.7 trillion.
Certainly, many of these so-called long-haulers experience relatively mild symptoms - such as loss of smell - which, while troublesome, are not disabling. But other symptoms are serious enough to be disabilities.
According to a recent study from the Federal Reserve Bank of Minneapolis, about a quarter of those with long COVID changed their employment status or working hours. That means long COVID was serious enough to interfere with work for 4 million people. For many, the issue was serious enough to qualify them as disabled.
Indeed, the Federal Reserve Bank of New York found in a just-released study that the number of individuals with disabilities in the U.S. grew by 1.7 million. That growth stemmed mainly from long COVID conditions such as fatigue and brain fog, meaning difficulties with concentration or memory, with 1.3 million people reporting an increase in brain fog since mid-2020.
Many had to drop out of the labor force due to long COVID. Yet, about 900,000 people who are newly disabled have managed to continue working. Without remote work, they might have lost these jobs.
For example, a software engineer at one of my client companies has struggled with brain fog related to long COVID. With remote work, this employee can work during the hours when she feels most mentally alert and focused, even if that means short bursts of productivity throughout the day. With flexible scheduling, she can take rests, meditate, or engage in activities that help her regain focus and energy. Without the need to commute to the office, she can save energy and time and reduce stress, which is crucial when dealing with brain fog.
In fact, the author of the Federal Reserve Bank of New York study notes that long COVID can be considered a disability under the Americans with Disability Act, depending on the specifics of the condition. That means the law can require private employers with fifteen or more staff, as well as government agencies, to make reasonable accommodations for those with long COVID. Richard Deitz, the author of this study, writes in the paper that “telework and flexible scheduling are two accommodations that can be particularly beneficial for workers dealing with fatigue and brain fog.”
The current drive to return to the office, led by many C-suite executives, may need to be reconsidered in light of legal and HR considerations. Arlene S. Kanter, director of the disability law and policy program at the Syracuse University College of Law, said that the question should depend on whether people with disabilities can perform their work well at home, as they did during Covid outbreaks. “[T]hen people with disabilities, as a matter of accommodation, shouldn’t be denied that right,” Kanter said.
Diversity benefits
But companies shouldn’t need to worry about legal regulations. It simply makes dollars and sense to expand their talent pool by 15% of an underrepresented minority. After all, extensive research shows that improving diversity boosts both decision-making and financial performance.
Companies that are offering more flexible work options have already gained significant benefits in terms of diverse hires. In its efforts to adapt to the post-pandemic environment, Meta, the owner of Facebook and Instagram, decided to offer permanent fully remote work options to its entire workforce. And according to Meta chief diversity officer Maxine Williams, the candidates who accepted job offers for remote positions were “substantially more likely” to come from diverse communities: people with disabilities, Black, Hispanic, Alaskan Native, Native American, veterans, and women. The numbers bear out these claims: people with disabilities increased from 4.7 to 6.2 percent of Meta’s employees.
Having consulted for 21 companies to help them transition to hybrid work arrangements, I can confirm that Meta’s numbers aren’t a fluke. The more my clients proved willing to offer remote work, the more staff with disabilities they recruited - and retained. That includes employees with mobility challenges. But it also includes employees with less visible disabilities, such as people with long COVID and immunocompromised people who feel reluctant to put themselves at risk of getting COVID by coming into the office.
Unfortunately, many leaders fail to see the benefits of remote work for underrepresented groups, such as those with disabilities. Some even say the opposite is true, with JP Morgan CEO Jamie Dimon claiming that returning to the office will aid diversity.
What explains this poor executive decision making? Part of the answer comes from a mental blindspot called the in-group bias. Our minds tend to favor and pay attention to the concerns of those in the group of people who seem to look and think like us. Dimon and other executives without disabilities don’t perceive people with disabilities to be part of their in-group. They thus are blind to the concerns of those with disabilities, which leads to misperceptions such as Dimon’s that returning to the office will aid diversity.
In-group bias is one of many dangerous judgment errors known as cognitive biases. They impact decision making in all life areas, ranging from the future of work to relationships.
Another relevant cognitive bias is the empathy gap. This term refers to our difficulty empathizing with those outside of our in-group. The lack of empathy combines with the blindness from the in-group bias, causing executives to ignore the feelings of employees with disabilities and prospective hires.
Omission bias also plays a role. This dangerous judgment error causes us to perceive failure to act as less problematic than acting. Consequently, executives perceive a failure to support the needs of those with disabilities as a minor matter.
Conclusion
The failure to empower people with disabilities through remote work options will prove costly to the bottom lines of companies. Not only are limiting their talent pool by 15 percent, they’re harming their ability to recruit and retain diverse candidates. And as their lawyers and HR departments will tell them, by violating the ADA, they are putting themselves in legal jeopardy.
By contrast, companies like Meta - and my clients - that offer remote work opportunities are seizing a competitive advantage by recruiting these underrepresented candidates. They’re lowering costs of labor while increasing diversity. The future belongs to the savvy companies that offer the flexibility that people with disabilities need.
