Something to keep in mind is that the rafting hypothesis is rarely alluding to a clump of leaves on a log carrying one pregnant rodent to an island where it's rescued by washing up on the beach. Big enough rivers actually produce floating islands. Interlocked root systems of semi aquatic plants sprawl out into shallow water. There's a build of sediment that gets trapped in these roots, and when conditions are right these mostly vegetation peninsulas can loose their anchoring, break off and float down river. In Columbia on the Megdalena river some German researchers found one such island slowly drifting down river. It was 80 meters in diameter, had mature tree growing on it and a troop of howler monkeys. These islands can sometimes work their way down river without being permanently caught on a bank, and make it out to the ocean. They are basically giant lily pads. Tide, currents, and winds can carry them far enough to run into and island beach if they don't capsize first. Which can bring dozens of new species to an island. Some of which may see their island populations go extinct. Some won't even make it but die on the way. But a few might adapt and find an open niche or take one over.
I'm just thinking of that one floating bunch of vegetation and whatnot that floats toward that bridge every year and a dozen people volunteer wirh boats to move the island back so it doesn't crash into the bridge. It's in the US. In Maine, I think. That was my first thought with this, haha. Your explanation makes a lot of sense, though.
Thank you for explaining! I was just thinking 'man rafting gets credit a whole lot more often than really makes sense...', but the way you describe it makes way more sense to me
The same thing happened with Madagascar's frogs - the Mantellidae got there and filled all the frog niches available. They have poison-dart frog lookalikes, tree frog lookalikes, even toad lookalikes!
@@ArawnOfAnnwn came toad populations stay in control in their native range. It's only when they get relocated that they get out of control because they have few predators outside their habitat. They're native to Costa Rica and common there, but they're not a threat to the native animals and enough animals eat them to keep them in check.

I hate how everyone thinks Aussie wildlife is dangerous. Yeah there's some deadly spiders and snakes, jelly fish and Crocs up north. But. We have no bears, no mountain lions/cougars/bobcats (I don't know if they're the same things or not), no coyotes and no wolves. I personally think north American wildlife is more dangerous.
@@lunchb0x1986 bobcats are a different, much smaller species that aren't known for attacking humans. Also, the top 10 most dangerous snakes all come from Australia. In fact, 20 out of 25 most venomous snakes are from Australia. The reputation's well earned.
I have heard the rafting thing referred to as "sweepstakes colonization" because of its unlikely odds and huge possible payoffs for the animals involved. Glad to see it explicated here, yes! Go tenrecs!
"endemic to Madagascar" and that explains everything: they took their chance and filled a lot of niches, the same way marsupials turned into an almost dog, an almost badger/wolverine, few other "almosts" and even a weirdo Kangaroo
All of those different tenrecs expressing evolutionary convergence with so many other mammals is also a really good example of DIVERGENT evolution, since they're all so much different from each other despite their shared origin.
Brilliant episode. I got that old feeling I use to get in school when I was learning something truly fascinating. It was rare because I didn't like school lol but still, great episode
@@terpsidance. if you’re talking about Shadow, that’s a misconception. If you’re talking about Surge, I don’t think the specific species of Tenrec was ever stated.

Pretty sure my mom's a Midwest Boomer Tenrec who got washed out to sea in the 1970s. She's also a mammal with a low metabolic rate. I think about 65% of Ohio/Pennsylvania is tenrecs. If it's quiet you can hear them making those cricket noises with their cloaca.
Off topic: I love the green hair look! My wife and I have been experimenting with different dyes for her hair and I occasionally mess with a bit of left over dye for my hair or beard (discovered the hard way that I have to make sure it doesn't have unpleasant fumes for beard dying...)
Mind you somehow until about 1000 years ago, tiny Hippos lived on Madagascar. They probably swam the 400km between african and the island, somehow (lower water level?). So the tenrec floting there isn't the wildest idea.

its divergent for the tenrecs, and convergent for the specific tenrec and another animal they are very similar to (Example, mole tenrec)

Ratking but tenrecs
"Holy crap, this tenrec has quills, and a vibrant coloring, and even chirps like a cricket." "Hmmmm yes You're right it _does_ live in a lowland"
