Hobbits were real.

No, not those hobbits.

I'm not talking about J.R.R. Tolkien's funny, pipe-smoking, jewelry-hating race of smaller people from "Lord of the Rings" fame.

Instead, "hobbit" is the nickname scientists have given to a real but diminutive human relative, known as Homo floresiensis, that lived about 60,000 years ago on the Indonesian island of Flores.

Real-life hobbits were only about three feet tall. What made these them so small? Living on an island.

As it turns out, a lot of species change size once they start living on islands. Big gets small and small gets big. Why? It depends on each species and each island. Different amounts and types of food might be one reason (a tiny island can't support a gigantic elephant, for example). On the flip side, a lack of predators might enable small animals to grow big.

In honor of weird evolutionary changes, here are eight creatures that got really weird after moving to islands.

1. The famous hobbits, in all their glory.

We weren't completely sure whether the hobbits really were a case of the island effect (or whether they were normal humans with an abnormality), but the recent discovery of the hobbit's ancestors suggests that they were. Their ancestors started big, but once they got to Flores, they quickly shrank to match the island's more restrictive ecosystem.

2. While humans shrank on Flores, lizards got big. Really big.

Hobbits would have shared the island with the gigantic Komodo dragons. These guys earn their draconic title — they can weigh as much as 300 pounds and can grow up to 10 feet long!

And these weren't the only giants on Flores. There are also giant rats and even gigantic storks.

3. Speaking of giant reptiles, the Galápagos took tortoises and said, You know what? These guys need to weigh as much as a polar bear.

The largest Galápagos tortoise ever seen weighed over 800 pounds.

4. Birds got in on the gigantism game too — few as enthusiastically as New Zealand's 12-foot-tall moa.

Up until the 15th century, New Zealand was home to nine different species of giant, flightless birds known as moa, which were preyed upon by the also-terrifyingly large Haast's eagle. (Not to be a slouch, Madagascar, that island off Africa, also had its version of gigantic fowl: the elephant bird).

5. The Mediterranean was home to a tiny elephant — that could just about fit under your sink!

These guys were known as "dwarf elephants" or "dwarf mammoths" and were found on Mediterranean islands like Sicily and Cyprus. Unfortunately, we're about 11,000 years too late to have our own personal three-feet-tall miniature elephants, which is just more proof that linear time is awful.

6. Tiny hippos too!

These guys pictured above are living pygmy hippos from West Africa, but their equally cute, equally tiny cousins once lived in the Mediterranean. Which just, gah, Cyprus — stop making all the places that don't have tiny animals like that look bad! Sadly, the tiny hippos died out about the same time as the tiny elephants.

7. At least California's Channel Islands kept their adorable tiny foxes.

In a surprise to no one, the Channel Island fox lives on the ... wait for it ... Channel Islands, located off the coast of California. The foxes only grow to about 20 inches long, half as big as their grey fox cousins on the mainland.

8. Cuba can keep its giant solenodons though.

The Cuban solenodon looks a lot like a shrew ... if a shrew was about two feet long and venomous.

All these unusual species — including hobbits — were able to evolve because of their unique island homes. But, today, many of these island ecosystems are in danger.

More than half of Hawaii's unique birds have been wiped out by newly introduced diseases, invasive species, and habitat loss — a pattern seen elsewhere too. Meanwhile climate change is changing weather patterns, destroying coral reefs, and even flooding some low-lying islands.

But we can still fight back and help preserve unique island ecosystems (and incredible big and small creatures).

By being careful about invasive species, protecting native ones, and, perhaps most importantly, weaning ourselves off fossil fuels, we can ensure the health of our islands — and make sure places for tiny, giant, or otherwise unusual animals, can thrive!

True

It takes a special type of person to become a nurse. The job requires a combination of energy, empathy, clear mind, oftentimes a strong stomach, and a cheerful attitude. And while people typically think of nursing in a clinical setting, some nurses are driven to work with the people that feel forgotten by society.

The Emperor of the Seas.

Imagine retiring early and spending the rest of your life on a cruise ship visiting exotic locations, meeting interesting people and eating delectable food. It sounds fantastic, but surely it’s a billionaire’s fantasy, right?

Not according to Angelyn Burk, 53, and her husband Richard. They’re living their best life hopping from ship to ship for around $44 a night each. The Burks have called cruise ships their home since May 2021 and have no plans to go back to their lives as landlubbers. Angelyn took her first cruise in 1992 and it changed her goals in life forever.

“Our original plan was to stay in different countries for a month at a time and eventually retire to cruise ships as we got older,” Angelyn told 7 News. But a few years back, Angelyn crunched the numbers and realized they could start much sooner than expected.

The energy in a hospital can sometimes feel overwhelming, whether you’re experiencing it as a patient, visitor or employee. However, there are a few one-of-a-kind individuals like Elaine Ahn, an operating room registered nurse in Diamond Bar, California, who thrive under this type of constant pressure.

Prior to baby formula, breastfeeding was the norm, but that doesn't mean it always worked.

As if the past handful of years weren't challenging enough, the U.S. is currently dealing with a baby formula crisis.

Due to a perfect storm of supply chain issues, product recalls, labor shortages and inflation, manufacturers are struggling to keep up with formula demand and retailers are rationing supplies. As a result, families that rely on formula are scrambling to ensure that their babies get the food they need.

Naturally, people are weighing in on the crisis, with some throwing out simplistic advice like, "Why don't you just do what people did before baby formula was invented and just breastfeed?"

That might seem logical, unless you understand how breastfeeding works and know a bit about infant mortality throughout human history.

Emily Calandrelli was stopped by TSA agents when she tried to bring her ice packs for pumped milk through airport security.

Traveling without your baby for the first time can be tough. And if you're breastfeeding, it can be even tougher, as you have to pump milk every few hours to keep your body producing enough, to avoid an enormous amount of discomfort and to prevent risk of infection.

But for Emily Calandrelli, taking a recent work trip away from her 10-week-old son was far more challenging than it needed to be.

Calandrelli is a mom of two, an aerospace engineer and the host of the Netflix kids' science show "Emily's Wonder Lab." She was recently taking her first work trip since welcoming her second child, which included a five-hour flight from Los Angeles to Washington, D.C. Calandrelli is breastfeeding her son and had planned to pump just before boarding the plane. She brought ice packs to keep the milk from spoiling during the flight, but when she tried to go through airport security, the TSA agents refused to let her take some of her supplies.
