There are no walruses in Iceland, but, at one time, there were hundreds. The timing of the walruses’ disappearance suggests that the population’s loss may be one of the earliest known examples of humans driving a marine species to local extinction.
The Ghost of Walruses Past
Walruses used to be a major feature of life in Iceland. Several settlements and landmarks along Iceland’s coast still bear names that refer to walruses, and a few of the medieval Sagas (the stories of the island’s early settler families) even mention them. The Saga of Hrafin Sveinbjarnarson, written down sometime in the late 1100s, tells the story of a chieftain who killed a walrus and brought its tusks and skull to Canterbury Cathedral in England. But the walruses themselves have been reduced to only a few ancient bones and tusks.

Did the walruses disappear before or after the Norse arrived? In other words, did the Norse kill off Iceland’s walruses, or did the population die of natural causes? Because Iceland has no living walruses today, historians have debated whether the place names referred to places where walruses were living when people arrived or just places where settlers found the skulls and tusks of long-dead animals. The walrus tusks that Hrafin Sveinbjarnarson delivered to England could have been part of a thriving Icelandic walrus population, but it could also have been only a lost wanderer from more distant shores.
To learn more about Iceland’s pinniped past, evolutionary genomicist Xenia Keighley of the University of Copenhagen and her colleagues radiocarbon dated and sequenced DNA from 34 samples of bones and tusks from walruses in the Icelandic Museum of Natural History. The DNA studies also showed that Iceland’s long-lost walruses were a distinct branch of the walrus family. The oldest walrus remains in the museum, dating to 5502-5332 BCE, were related to the ancestors of today’s Atlantic walrus population. More recent samples, though, belonged to a separate mitochondrial branch of the walrus family tree, genetically distinct from every group that’s known in the North Atlantic—including the older Icelandic walruses.
“I would suspect that the most recent clade represent a colonization event that replaced the lineage represented by the old sample, rather than the old sample being a direct ancestor to the more recent clade,” co-author Morten Olsen, also an evolutionary genomicist at the University of Copenhagen, told Ars.
Blame the Vikings
So what happened to Iceland’s walruses? As always, the answer is complex, but much of the blame falls squarely on the shoulders of the Norse. Settlers arrived in Iceland and began hunting walrus for the European ivory trade at a time when Iceland’s walrus population was already struggling with a shifting environment and a series of volcanic eruptions.
Walrus ivory was a major trade commodity in markets across Europe for much of the early Middle Ages, and the Norse hunted walrus around most of their territory in the North Atlantic. According to a 2018 study of DNA from walrus skulls and tusks found in Western European archaeological sites, most of Europe’s supply of walrus ivory came from a walrus clade (a group of related animals with a common ancestor) living in Greenland, which was home to tens of thousands of walruses. Iceland’s much smaller walrus population would have been a drop in the bucket by comparison, but the ivory trade would still have put pressure on Iceland’s small population.
When the first Norse hunters reached them, Icelandic walruses were already facing challenges from the Medieval Warm Period (700 to 1100 CE). A few centuries of relatively warm climate in the North Atlantic were helpful to human explorers, but not so great for walruses, which rely on sea ice as a place to haul themselves out of the water. And at the same time, volcanoes erupted several times near some of the walruses’ key haul-out sites on land. It’s no wonder the walruses couldn’t survive all of that and Vikings.
Some evidence suggests that a Roman fishing industry may have wiped out grey whales in the North Atlantic a few hundred years before the Viking Age, but otherwise the Norse may have been the first to wipe out a whole population of animals for profit.

It would be hard to top the 2018 enterprise M&A total of a whopping $87 billion, and predictably this year didn’t come close. In fact, the top 10 enterprise M&A deals in 2019 were less than half last year’s, totaling $40.6 billion.
This year’s biggest purchase was Salesforce buying Tableau for $15.7 billion, which would have been good for third place last year behind IBM’s mega deal plucking Red Hat for $34 billion and Broadcom grabbing CA Technologies for $18.8 billion.
Contributing to this year’s quieter activity was the fact that several typically acquisitive companies — Adobe, Oracle and IBM — stayed mostly on the sidelines after big investments last year. It’s not unusual for companies to take a go-slow approach after a big expenditure year. Adobe and Oracle bought just two companies each with neither revealing the prices. IBM didn’t buy any.
Microsoft didn’t show up on this year’s list either, but still managed to pick up eight new companies. It was just that none was large enough to make the list (or even for them to publicly reveal the prices). When a publicly traded company doesn’t reveal the price, it usually means that it didn’t reach the threshold of being material to the company’s results.
As always, just because you buy it doesn’t mean it’s always going to integrate smoothly or well, and we won’t know about the success or failure of these transactions for some years to come. For now, we can only look at the deals themselves.

The business of selling consumer goods and services online is a relatively young endeavor across Africa, but ecommerce is set to boom.
Over the last eight years, the sector has seen its first phase of big VC fundings, startup duels and attrition.
To date, scaling e-commerce in Africa has straddled the line of challenge and opportunity, perhaps more than any other market in the world. Across major African economies, many of the requisites for online retail — internet access, digital payment adoption, and 3PL delivery options — have been severely lacking.
Still, startups jumped into this market for the chance to digitize a share of Africa’s fast growing consumer spending, expected to top $2 billion by 2025.
African e-commerce 2.0 will include some old and new players, play out across more countries, place more priority on internet services, and see the entry of China.
But before highlighting several things to look out for in the future of digital-retail on the continent, a look back is beneficial.
Jumia vs. Konga
The early years for development of African online shopping largely played out in Nigeria (and to some extent South Africa). Anyone who visited Nigeria from 2012 to 2016 likely saw evidence of one of the continent’s early e-commerce showdowns. Nigeria had its own Coke vs. Pepsi-like duel — a race between ventures Konga and Jumia to out-advertise and out-discount each other in a quest to scale online shopping in Africa’s largest economy and most populous nation.
Traveling in Lagos traffic, large billboards for each startup faced off across the skyline, as their delivery motorcycles buzzed between stopped cars.
Covering each company early on, it appeared a battle of VC attrition. The challenge: who could continue to raise enough capital to absorb the losses of simultaneously capturing and creating an e-commerce market in notoriously difficult conditions.
In addition to the aforementioned challenges, Nigeria also had (and continues to have) shoddy electricity.
Both Konga — founded by Nigerian Sim Shagaya — and Jumia — originally founded by two Nigerians and two Frenchman — were forced to burn capital building fulfillment operations most e-commerce startups source to third parties.
That included their own delivery and payment services (KongaPay and JumiaPay). In addition to sales of goods from mobile-phones to diapers, both startups also began experimenting with verticals for internet based services, such as food-delivery and classifieds.
While Jumia and Konga were competing in Nigeria, there was another VC driven race for e-commerce playing out in South Africa — the continent’s second largest and most advanced economy.
E-tailers Takealot and Kalahari had been jockeying for market share since 2011 after raising capital in the hundreds of millions of dollars from investors Naspers and U.S. fund Tiger Global Management.
So how did things turn out in West and Southern Africa? In 2014, the lead investor of a flailing Kalahari — Naspers — facilitated a merger with Takealot (that was more of an acquisition). They nixed the Kalahari brand in 2016 and bought out Takelot’s largest investor, Tiger Global, in 2018. Takealot is now South Africa’s leading e-commerce site by market share, but only operates in one country.
In Nigeria, by 2016 Jumia had outpaced its rival Konga in Alexa ratings (6 vs 14), while out-raising Konga (with backing of Goldman Sachs) to become Africa’s first VC backed, startup unicorn. By early 2018, Konga was purchased in a distressed acquisition and faded away as a competitor to Jumia.
Jumia went on to expand online goods and services verticals into 14 Africa countries (though it recently exited a few) and in April 2019 raised over $200 million in an NYSE IPO — the first on a major exchange for a VC-backed startup operating in Africa.
Jumia’s had bumpy road since going public — losing significant share-value after a short-sell attack earlier in 2019 — but the continent’s leading e-commerce company still has heap of capital and generates $100 million in revenues (even with losses).
Airbnb’s New Year’s Eve guest volume shows its falling growth rate

Hello and welcome back to our regular morning look at private companies, public markets and the gray space in between.
It’s finally 2020, the year that should bring us a direct listing from home-sharing giant Airbnb, a technology company valued at tens of billions of dollars. The company’s flotation will be a key event in this coming year’s technology exit market. Expect the NYSE and Nasdaq to compete for the listing, bankers to queue to take part, and endless media coverage.
Given that that’s ahead, we’re going to take periodic looks at Airbnb as we tick closer to its eventual public market debut. And that means that this morning we’re looking back through time to see how fast the company has grown by using a quirky data point.
Airbnb releases a regular tally of its expected “guest stays” for New Year’s Eve each year, including 2019. We can therefore look back in time, tracking how quickly (or not) Airbnb’s New Year Eve guest tally has risen. This exercise will provide a loose, but fun proxy for the company’s growth as a whole.
Before we look into the figures themselves, keep in mind that we are looking at a guest figure which is at best a proxy for revenue. We don’t know the revenue mix of the guest stays, for example, meaning that Airbnb could have seen a 10% drop in per-guest revenue this New Year’s Eve — even with more guest stays — and we’d have no idea.
So, the cliche about grains of salt and taking, please.
But as more guests tends to mean more rentals which points towards more revenue, the New Year’s Eve figures are useful as we work to understand how quickly Airbnb is growing now compared to how fast it grew in the past. The faster the company is expanding today, the more it’s worth. And given recent news that the company has ditched profitability in favor of boosting its sales and marketing spend (leading to sharp, regular deficits in its quarterly results), how fast Airbnb can grow through higher spend is a key question for the highly-backed, San Francisco-based private company.
- 2009: 1,400
- 2010: 6,000 (+329%)
- 2011: 3,1000 (+417%)
- 2012: 108,000 (248%)
- 2013: 250,000 (+131%)
- 2014: 540,000 (+116%)
- 2015: 1,100,000 (+104%)
- 2016: 2,000,000 (+82%)
- 2017: 3,000,000 (+50%)
- 2018: 3,700,000 (+23%)
- 2019: 4,500,000 (+22%)
In chart form, that looks like this:
Let’s talk about a few things that stand out. First is that the company’s growth rate managed to stay over 100% for as long as it did. In case you’re a SaaS fan, what Airbnb pulled off in its early years (again, using this fun proxy for revenue growth) was far better than a triple-triple-double-double-double.
Next, the company’s growth rate in percentage terms has slowed dramatically, including in 2019. At the same time the firm managed to re-accelerate its gross guest growth in 2019. In numerical terms, Airbnb added 1,000,000 New Year’s Eve guest stays in 2017, 700,000 in 2018, and 800,000 in 2019. So 2019’s gross adds was not a record, but it was a better result than its year-ago tally.
