“The Zoologist’s Guide to the Galaxy: What Animals on Earth Reveal About Aliens – and Ourselves”
By MARTIN ZEILIG “That life exists elsewhere in the universe seems almost inevitable,” Dr. Arik Kershenbaum writes in this intriguing and entertaining book.
“That we could know anything about it seems almost impossible. But my goal is to show you that we can actually say a great deal about what aliens must be like, how they live, and how they behave.”
Dr Kershenbaum is a zoologist, College Lecturer, and Fellow at Girton College, University of Cambridge, says his bio. He has researched animal vocal communication for the past ten years in Europe, Israel and the United States and has published more than 20 academic publications on the topic.
He is also a member of the international board of advisors for METI.org, a think tank on the topic of Messaging Extra Terrestrial Intelligence. Arik has done extensive field work on animal communication, following wolves around Yellowstone National Park and the forests of central Wisconsin to uncover the meaning of their different kinds of howls, as well as decoding the whistles of dolphins among the coral reefs of the Red Sea, and the songs of hyraxes in the Galilee.
Using his own trained understanding of life on Earth and Darwin’s theory of evolution—“which applies throughout the universe,” according to Dr. Kershenbaum’s book—Dr. Kershenbaum explains what alien life must be like: how these creatures will move, socialize, and communicate.
Dr. Kershenbaum agreed to do an interview with The Jewish Post & News.
JP&N: Why did you feel it necessary to write this particular book?
AK: Until recently, it was absolutely fine to restrict thoughts about alien life to science fiction. It was fun, and it was entertaining, and it didn’t have anything to do with science, or biology, or real life of any kind. All that is changing now.
Our understanding of the possibilities of life in the universe has blossomed as our technology for examining other planets has moved forward in leaps and bounds. Difficult as it is, we’re going to have to put aside the science fiction, and make a study of alien life into a well-grounded scientific discipline. And everyone should realize that the universe almost certainly is teeming with life – now we just need to find it.
But the search for extraterrestrial life isn’t enough. It’s also important to think about what that life is going to be like. What are the principles that determine how life evolves elsewhere in the universe? Will it be similar to life on Earth, or totally different?
These questions were very hypothetical as long as the chances of discovering life on other planets was remote in the extreme. Now that scientists are quietly optimistic, we all need to make an adjustment.
Fortunately, the Earth is an amazingly diverse habitat, full of life in the most surprising range of possibilities. Even if the conditions on other planets are very different from here, we have learned enough on Earth about the processes of evolution, and the forces that drive the properties of life, so we can apply those principles more generally to whatever exists on other worlds.
JP&N: Daniel Fabrycky, assistant professor of astronomy and astrophysics at the University of Chicago, has argued that “over billions of years no intelligent aliens have made it to the point of reaching Earth, meaning humanity has dismal prospects for space exploration and expansion.”
What would you say in response to Prof. Fabrycky?
AK: I think that the current climate crisis gives us a clue to how unlikely it is that humanity will survive to get the chance to explore space. It has always been thought that the process of life arising from “non-life” (i.e. a mixture of chemicals) was the limiting step in the distribution of civilizations throughout the universe.
But a more serious barrier might be the challenge of surviving rapid technological advances, without destroying ourselves through environmental destruction and war. It may be that many planets produced civilizations like ours, but they’re all dead.
However, there are many other possible explanations for why we’ve never noticed any alien civilizations. The laws of physics, as we know them, seem to make travel between the stars almost impossible. Maybe alien civilizations know things that we don’t, but maybe we’ve got things right, and aliens haven’t developed warp drive simply because it’s not possible.
As for not having received any radio or similar signals from outer space, we’ve only been looking for the last few decades – we only invented radio just over 100 years ago! – and we’ve never had funding to do a really comprehensive search for intelligent signals. I’d say that Fabrycky may be right, but that it’s too early to rule out a better possibility.
JP&N: What else would you like our readers to know about this topic?
AK: Life evolves according to the laws of biology, just like balls roll according to the laws of physics. We’ve come to understand a lot about these biological laws, and we can apply them to make predictions about life, even on other planets.
We can’t predict what colour aliens will be, but we can say a lot about the way they will interact, and solve problems like moving around, finding food, and cooperating or competing with other animals. Much of the underlying diversity of life on Earth – plants vs. animals, predators vs. prey, etc – arises as the result of common rules, and that means that this diversity is going to exist on other planets too.
“A direct biological comparison between us and alien intelligences could bring us to a more complete and more satisfying description of life in the universe. Perhaps we will be able to come to an acceptance of a wider type of humanity; one that has room for creatures that don’t look like us, no matter what planet they inhabit,” Dr. Kershenbaum writes in “The Zoologist’s Guide to the Galaxy.“

The Gaza Peace Plan is not a Done Deal, but an Opening
By HENRY SREBRNIK (Oct. 23, 2025) The idea that Hamas will voluntarily disarm, that international forces will deploy in the Gaza Strip, and that the process of building a Palestinian government by people like former British Prime Minister Tony Blair, in which a disarmed Hamas does not participate, are false hopes, if not fantasies. But does this mean U.S. President Donald Trump’s peace plan was useless? Of course not.
Trump understood the necessity of bringing the war to an end. But he also believed that endless debate among experts or, worse, historian and lawyers, would never produce an agreement. He presented an offer – actually, an ultimatum – to Benjamin Netanyahu and Hamas that neither could refuse: immediate, unconditional and complete release of all hostages and missing persons, something the Israeli public longed for, in exchange for a final end to the war, which a humbled Hamas needed.
Two years of war has left Hamas weaker than it had been in decades. Israeli bombardments had shattered the group’s military capabilities and depleted its arsenals. In many neighborhoods, control had drifted to local clan networks and tribal councils. This hinted at something that could one day replace Hamas’s iron grip. To prevent this, Hamas has been ruthlessly murdering all potential rivals in the areas of Gaza it controls since the ceasefire went into effect.
Despite the severe degradation of its military capabilities during the war, Hamas still has more soldiers and weapons than all its rival factions in Gaza combined. Hamas has managed to redeploy approximately 7,000 militants to reassert control over the territory. They have publicized photographs and videos of their forces murdering and torturing; the victims include women and children.
The ceasefire is a temporary reprieve for Hamas: a chance to regroup, rearm, and prepare for the next round of fighting. In Islamist political thought there’s a word for it, hudna — a temporary truce with non-Muslim adversaries that can be discarded as soon as the balance of power shifts. Then the time for jihad will arrive again. Hamas was established in 1987 and isn’t going to disappear.
In fact Hamas also says it expects an interim International Transitional Authority to hire 40,000 Hamas employees, and Hamas spokesman Basem Naim says he expects its fighters to be integrated into a post-transition Palestinian state.
Still, Trump has succeeded in ending the current war in Gaza, where Joe Biden failed. Biden’s national security team, drawn almost entirely from his supposed expert class, didn’t even see the crisis coming. Just five days before the attack, National Security Adviser Jake Sullivan had published an article in Foreign Affairs in which he wrote that “the region is quieter than it has been for decades.”
Biden also had insulted the Saudi crown prince, Mohammed bin Salman, by publicly condemning the 2018 murder of Saudi dissident journalist Jamal Khashoggi. And, of course, there was Biden’s poor relationship with Netanyahu, and his chronic inability to get the Israeli prime minister to do what he wanted.
By contrast, Trump returned to office with substantially more influence in both the Gulf and Israel, based on his first-term successes in the Middle East, especially the Abraham Accords (for which he’s never been praised by his political enemies).
Four Arab countries formally recognized Israel, beginning with the United Arab Emirates and Bahrain, followed by Sudan and Morocco. The next stage was intended to include Saudi Arabia. One motive put forward by some analysts for the October 7 attacks was that they were intended to provoke Israel into a response that would derail Saudi Arabia’s admission.
Instead of sitting Israelis and Arabs in a room and expecting them to negotiate an outcome, Trump’s approach has been to exert leverage through other players in the region, especially, Egypt, Turkey, and – most importantly – Qatar.
In Jerusalem, they call Qatar “the spoiler state.” Israelis describe the emirate as two trains running behind the same engine. One, led by the Qatari ruler’s mother and brother, supports the Muslim Brotherhood and is an unmistakable hater of Israel. The other, led by the prime minister, Mohammed bin Abdulrahman bin Jassim Al Thani and several other senior figures, seeks rapprochement with the West.
The Qataris were shocked when Israeli jets on Sept. 9 conducted an airstrike in Doha targeting the leadership of Hamas. They then signed onto Trump’s peace plan at a meeting in New York Sept. 23, hosted by Trump and Qatari Emir Sheikh Tamim Ibn Hamad Al Thani, and attended by the leaders of eight Arab states, along with members of the Organization of Islamic Cooperation.
Netanyahu was then browbeaten into accepting the plan (and also forced to apologize to the Emir for the airstrike). It was somewhat ironic that the airstrike made the peace plan possible. As well, Trump’s attack on Iran’s nuclear facilities in June gave this negotiation some very sharp teeth.
“If you would rather leave peacemaking to the historians and diplomats, then you may wait a long time for wars to end,” suggested Niall Ferguson of the Hoover Institution at Stanford University, in an Oct. 15 Free Press article. His advice? Go to the “deal guys: They get the job done.”
In a sense, both Israel and Hamas had accomplished their goals. Israel had broken the Iranian axis of terror by eliminating Hezbollah and Hamas as a fighting force, along with the Iranian nuclear threat. Hamas had succeeded in luring Israel into a trap that led it to become hated and isolated around the world. This included the labelling of Israel as genocidal and the global call for a Palestinian state.
The rest of the 20-point peace plan will be addressed in a step-by-step fashion. Meanwhile, Israel must ensure that it retains freedom of action in Gaza, by decisive action against any attempt by Hamas to rebuild its army, its rockets, its battalions and its divisions.

Why Fitness Routines Fall Apart — and How to Rebuild Yours
Every spring, gyms see a flood of hopeful faces. New shoes, fresh playlists, unwavering intentions, by mid-summer? Half of them vanish into the fog of abandoned routines. The story repeats year after year until it starts to feel almost scripted. Why does enthusiasm evaporate? The easy answer involves willpower but that explanation misses the point. Habits don’t fail because people are weak. Life stress, boredom, and monotony ruin routines. Timely lever pulls can change narratives. The hardest part is persevering when motivation wanes.
Mistaking Motivation for Momentum
Most chase that opening surge, the lightning strike of motivation, but then stop searching once enthusiasm fizzles. A scroll through sites like PUR Pharma (pur-pharma.is/) or a glimpse of an influencer’s progress triggers a burst of action: new workout gear ordered, plans scribbled in planners destined for dusty drawers. Yet momentum fades when small setbacks pop up (a late meeting here, rainy weather there). Real progress comes from building systems stronger than any fleeting pep talk. Those who frame fitness as something owed to motivation end up back at square one every time life interrupts, which it always does.
Overcomplicating Everything
It’s tempting to turn wellness into a science fair project with spreadsheets and specialized equipment lined up on day one. This is the allure of complexity disguised as seriousness, a new diet paired with seven types of supplements and four color-coded bottles. Simplicity gets lost in the noise almost instantly. Most successful routines rely on two principles: keep it simple and keep showing up even when everything else is chaos outside those gym walls. Anyone insisting that perfection is required before taking step one has already constructed an excuse not to begin at all.
Forgetting Fun Completely
Who decided exercise must hurt or look like punishment? Somewhere along the line, fun got swapped out for grind culture and “no pain, no gain.” That isn’t just unappealing, it’s unsustainable over months or years. If sessions feel like torture devices borrowed from medieval times, nobody should be surprised when commitment falters fast. Seek activities that actually spark some joy or curiosity, a dance class instead of yet another treadmill session, maybe, or play a pickup game rather than slogging through solo circuits again and again.
Ignoring Recovery (and Reality)
Sleep deprivation, disguised as discipline, fools anyone, except perhaps uncritical Instagram followers. Ignoring recovery turns ambition into tiredness faster than any missed session. Because bodies break without rest, routines must breathe with owners. Cycling, real leisure, and honest self-checks regarding weekly goals build endurance, not continual pushing.
Conclusion
Change rarely arrives by force alone but usually grows quietly from patterns repeated imperfectly over time, even if last month looked nothing like this week so far. Drop the hunt for nonstop inspiration. Instead of breaking behaviors at the first hint of stress or boredom, build habits that last. People who rebuild methodically after every stumble or detour make progress, not those who peak and then fall.

How DIY Auto Repairs Can Help You Cut Costs—Safely
Regular maintenance and minor repairs are the greatest approach for many car drivers to save money without sacrificing dependability. DIY repairs can save you a lot of money over the life of your car since most of the expense is in the labour. DIY helps you learn how things work and notice tiny issues before they become costly ones. Every work requires planning, patience, and safety.
Test Your Talents with Safe Limits
DIY solutions succeed when one is honest about their talents. Wiper blades, air filters, and occupant filters are beginner-friendly. With the correct equipment, intermediate owners can replace brake pads, spark plugs, coolant, and brake fluid. Pressurized fuel, high-voltage hybrids, airbags, and timing components are risky. Only professionals should manage them. Limitations protect you and your car. Drivers trust sources like Parts Avenue to find, install, and schedule manufacturer-approved work.
Set Up a Reliable Workspace and Tools
Good tools pay for themselves quickly. Ratchets, torque wrenches, combination wrenches, heavy jack stands, and wheel chocks are essential. It is advisable to engage specialists for specific tasks. A clean, flat, well-lit, and open space is essential. Please take your time. While working, keep a charged phone nearby to read repair instructions or write torque patterns.
Find the Problem before Replacing the Parts
It may cost more to replace something without diagnosing it. Instead of ideas, start with symptoms. OBD-II readers detect leaks, sounds, and DTCs. Simple tests like voltage, smoke indicating vacuum leaks, pad thickness, and rotor runout might reveal failure. A good analysis saves components, protects surrounding parts, and fosters future trust.
Maintenance That Pays off is Most Crucial
Jobs compensate for time and tools differently. Prioritize returns and maintenance. Change the oil and filter, rotate the tires, evaluate the air pressure, replace low brake fluid, clean the coolant with the right chemicals, and replace belts and filters before they fail. These items extend automotive life, stabilize fuel efficiency, and reduce roadside towing issues that can take months to resolve.
Do as Instructed, Utilize Quality Parts, and Follow Torque Requirements
Understand the service. Set the jacking points, tighten the screws in the appropriate order, and use threadlocker or anti-seize as suggested by the maker. Rotor wear can cause leaks, distortions, or broken threads. Choose components that meet or exceed OEM requirements and fit your car’s VIN, engine code, and manufacturing date. Cheap parts that break easily cost extra.
Test, Record, and Discard Carefully
Safely test the system before patching. Check under the car for drops, bleed the brakes again, and check fluid levels after a short drive. Note torques, parts, miles, and repair date. Photo and document storage for car sales. Properly dispose of oil, filters, coolant, and brake fluid. Controlling hazards protects your community and workplace.
Know When to Seek Professional Help
Self-employed individuals recognize their constraints. If a task is challenging, requires special instruments, or involves safety, consult an expert. Collaboration makes cars safer, cheaper, and more efficient. Selecting, planning, and implementing processes properly improves performance, lowers costs, and ensures safety.
