Nómade the elephant was born without tusks. Now her mutation is mainstream.

Evolution could help defend elephants from poachers — but that might not be a good thing.

Nómade the elephant was born without tusks. Now her mutation is mainstream.

Growing up in war-torn Mozambique wasn't easy for Nómade the elephant.

Mozambique, a southeastern African nation, gained its independence from Portugal in 1975. Then two years later, the Cold War found its way onto Mozambican soil in a bloody conflict that lasted until the mid-1990s and claimed up to a million human lives and displacing even more.

When the human forces weren't directly at each other's throats, they scavenged the savannah for animals they could kill for meat and ivory to trade for weapons or cash. But Nómade survived, along with 11 of her sisters, thanks in part to a miracle mutation that left them without tusks.

By the end of the war, the African elephant population in the Mozambique park where Nómade lived had been reduced by more than 90%.

Half of the females left alive were tuskless, just like Nómade.

Tusks are a crucial survival tool for elephants and, unfortunately, one of the main reasons why people try to kill them. While those lengthy incisors obviously make great weapons, elephants also rely on them for foraging in the dirt for minerals or food as well as scraping bark off trees or bending down branches to reach tasty goods. They're handy as a place to rest those big, heavy trunks on, too.

In typical animal fashion, however, males tend to have the mightier tusks, which they rely on to show off their elephant sexiness. It also means that they get poached in much higher numbers. As a result, the tusklessness gene has only really passed down the maternal side of the African elephant family tree, to elephants like Nómade.

This is the epitome of evolution in action: a rare mutation that grows more common over several generations when it turns out to be a blessing for survival.

Back in the 1930s, tusklessness was estimated to affect about 1% of both African elephant genders; today, there are parts of the continent where 98% of the females are born without tusks. 'Cause who's gonna hunt 'em if there isn't ivory to sell?

It turns out the same tusklessness that saved these females' lives might also be leaving a lasting impact on the whole of African elephant society.

Elephants are, of course, incredibly smart and social creatures. "But the scars of poaching last a very long time," according to Joyce Poole, Ph.D., co-founder and co-director of the ElephantVoices, a conservation group that works with Gorongosa National Park in Mozambique, where Nómade and her family roam.

Having lived under the threat of violence for so long has left many elephants with the equivalent of a broken home, Poole explains. "When a family loses a matriarch, the possibility of calf survival drops because there's no one to take care of the young." For example, the first few times she encountered Nómade, she says, "she was in a different group. A similar configuration of animals, but a different configuration every time." (That's also how she got her name — "nomad" in Portuguese).

To make matters worse, many of the females that do survive past childhood don't even reach full sexual maturity — both from increased stress levels and the fact that, well, there just aren't enough males left to go around, which means they probably aren't going to get pregnant. As a result, the rate of tuskless elephants just keeps going up because the males with tusks are dying out faster than they can be replaced.

"There's also pervasive myth — I'd call it an old wives' tale — that tuskless females are more aggressive than elephants with tusks," Poole says.

To be fair, there are some aggressive tuskless females, particularly in Nómade's family. In another early encounter at Gorongosa, one of Nómade's sisters led a massive mob of more than 30 elephants straight at Poole's safari truck, a move which earned her the name Corajosa, or "Courageous One."

But that behavior wasn't because of her tusklessness, Poole explains. "These are some of the most aggressive elephants in Africa because of what they've been through, and they pass that behavior down from one generation to the next."

Fortunately, Corajosa, Nómade, and the rest of their kin have warmed up to Poole over time. They also have another tool to make up for their lack of tusks: their trunks. "They're such smart animals and the trunk is such a magnificent organ that they are able to compensate," Poole says. "It can push over a tree or caress a baby … it's a magnificent thing to have."

On one hand, these African "tusklesses" are proof of evolution in progress.

On the other hand, it's also a frightening example of the damage that human intervention can really do. What was once a genetic survival advantage has now become the exact opposite — and it's likely that that trend will continue.

"If we're able to bring poaching and the illegal trade, then over generations, the tusklessness will decline," says Poole. "But that's going to take a long, long time."

There is a silver lining, however. While half of the females who lived through the war in Mozambique are tuskless, only about a third of the elephants born since then have the same condition. And the fact that they can live for upwards of 70 years means that, if things do improve, we'll actually be able to observe the difference across generations. It's one thing to know that nature always finds a way; it's another thing entirely to see that change in action.

Increasingly customers are looking for more conscious shopping options. According to a Nielsen survey in 2018, nearly half (48%) of U.S. consumers say they would definitely or probably change their consumption habits to reduce their impact on the environment.

But while many consumers are interested in spending their money on products that are more sustainable, few actually follow through. An article in the 2019 issue of Harvard Business Review revealed that 65% of consumers said they want to buy purpose-driven brands that advocate sustainability, but only about 26% actually do so. It's unclear where this intention gap comes from, but thankfully it's getting more convenient to shop sustainably from many of the retailers you already support.

Amazon recently introduced Climate Pledge Friendly, "a new program to help make it easy for customers to discover and shop for more sustainable products." When you're browsing Amazon, a Climate Pledge Friendly label will appear on more than 45,000 products to signify they have one or more different sustainability certifications which "help preserve the natural world, reducing the carbon footprint of shipments to customers," according to the online retailer.

In order to distinguish more sustainable products, the program partnered with a wide range of external certifications, including governmental agencies, non-profits, and independent laboratories, all of which have a focus on preserving the natural world.

An unusual story out of England shows just how interconnected the world is in 2020.

On January 2, 17-year-old Aidan Jackson of Widnes, England, just outside of Liverpool, was chatting and playing an online game with his friend, Dia Lathora, from Texas. Aidan was alone in his bedroom upstairs, while his parents were on the first floor watching television.

Aidan is a student studying graphics and photography with a recent history of seizures. At around 9 pm that night, Aidan began making sounds that didn't sound right to Dia.

"I just put my headset back on and I heard what I could only describe as a seizure, so obviously I started to get worried and immediately started asking what was going on and if he was OK," Dia told the Liverpool Echo.

I've never been a gardener. I love the idea, but my history of killing plants isn't terribly inspiring. However, this year is different. I am doggedly determined to grow all the things because I will not allow 2020 to defeat me.

Is there a better symbol of hope than a garden? Planting a seed means you believe the future is imminent. Watching a sprout emerge from the soil and grow into a flourishing plant means life goes on. In addition, reaping the fruits and veggies of your efforts and giving thanks for the bounty that nature provides is perhaps the most basic, fundamental human act I can think of.

As if we haven't had enough strange things happen this year (which we're only two weeks into, by the way), you may have noticed a sudden proliferation of sea shanty videos come through your social media feeds. While a welcome alternative to the footage of violent insurrection and rising pandemic death tolls in the U.S., the question is: Why sea shanties, and why now?

Though there's actually a wide range of sea shanty communities online, what brought it into the mainstream was a TikTok video from Scottish singer, Nathan Evans, pounding a drum and singing a well-known shanty, "The Wellerman."


Another singer, Luke Taylor, added some bass harmony to it, taking it up a significant notch.
