Wow! Good video idea! I had no idea about the different echolocation modes in bats. I'm glad that human echolocation was brought up. I'd be fascinated to see studies on how the brain restructures during that learning process (presumably, after FMRIs get quietter.) Also, if whales use jaw-assisted hearing rather than ear-only to exholocate, does that mean marine reptiles might have had access to that method? As a suggestion, maybe another convergence video on electro reception might make sense (pun intended).

Bats are pretty recent on the evolutionary scale. Only around 60 million years if we're generous and deliberately overshoot to predict un discovered specimens, probably closer to 52 million however. Birds evolved flight around 150 million years ago, and losing flight in a secondary manner that has convincing evidence on short notice doesn't show up anywhere I could find until around 66 million years ago. Though another study predicts that number might be closer to 65 or 64 million years ago. Birds were losing flight while bats were figuring it out. There's also just more species of bird giving them more chances to get weird compared to bats. Losing flight in birds is also very rare. Almost all flightless birds are related in specific families, and almost all those families have certain specific traits that are found in their flying members that make the step to a surface bound lifestyle something that can be worked into due to already living a lifestyle that needs very little flight. It also took a long while to develop the earlier traits that lead to secondarily losing flight in the first place. For example penguins seemed to evolve their aquatic lifestyle before losing flight, as an example of something that leads to flightlessness. There's also an argument that certain burrow dwelling species of bird might actually be on their way to flightlessness, just as an example of the type of prerequisite required for it to happen. Bats, being so comparatively recent, just haven't had a chance to develop towards a niche far enough to lose flight, though some species seem to be on their way. It just hasn't had enough time to happen. The first step needed would be for a more terrestrial species to evolve. Something suitable for spending long amounts of time walking, which has happened, or bats who prefer to climb rather than fly. After that give it some time. It seems to be happening, just we're not there yet.

about humans being able to echolocate: any human who can hear does it all the time without realizing and it is very important for humans to function correctly because the brain uses the information gained from hearing noise echo around us to supplement what our eyes pick up. this becomes very apparent when the info gained from the eyes and the echoes don't match up, like in one of those sound isolated recording rooms, the eyes see walls, but the ears hear no echo, which can be greatly disorienting, most people experience minor discomfort, but some experience headaches and nausea when in such a room for too long.

Flight! Flight! Flight! My ornithology courses and just about every book on avian flight always talks about the "requirements" for flight, an inevitable lists traits that other lineages don't have - such as needing a large keel bone, the absence of teeth, or laying eggs instead of going through prolonged pregnancies. Neither bats nor pterosaurs have keel bones, bats, many pterosaurs, and some early birds all had/have teeth, and bats go through pregnancy, give birth to unusually large pups, and often carry the pup during flight despite their already large size.

I find it interesting how cetaceans and bats are related. Not only that, but so many of their cousins are also very good at using their auditory sense for 3D spatial skills. Like while bats and whales have active sonar, their cousins all have passive sonar. On the other hand, rabbits, primates and rats all came from an branch that separated off from them long ago. Our branch seems to excel at problem solving and memory. Yes, rabbits have VERY good memory. Their problem solving skills are less than the rest of the group, but they are specialist herbivores now that have diverged highly from the rest of our group. And they are not bad per say, just meh at problem solving. Anywho, I have a working theory that while most early mammals and proto mammals were some form of rat body plan generalist, they differentiated and found separate niches through brain evolution and the latter mentioned facts about various mammals are an echo of that distant time. I am not saying the ancestor of bats, whales and cats could echolocate and our earliest ancestors that deviated were the spacial and memory grande masters of their day, but that early edge was there. Slightly sharper and maybe more of a hoarder vs the bat/whale/cat ancestor being better at hearing a bump in the night and "visualizing" where it is at. So while echolocation evolved multiple times in mammilla, the more passive version is a deep ancestral trait.

Just a quick thought I just had concerning the debate of how many times echolocation evolved in bats. You explained that one line of evidence suggests that it evolved convergently in the two lineages of bats, whereas the other line of evidence, including fossils, indicate it evolved once, and was then lost in pteropodids. Here is my thought: What if it was lost not in pteropodids but in the common ancestor of both pteropodids and rhinolophids, and then re-evolved in rhinolophids? Then, in a way, both hypotheses would be correct, and would provide and explanation for the seemingly contradictory lines of evidence.

I can imagine that echolocation is such a widespread ability because almost all animals with some hearing capability are theoretically able to use it to some extent, even those who don't need to or aren't commonly known for it (for example humans), Thus making it easy to evolve as soon as selective pressure makes it a neccessary advantage, for example for nocturnal animals. If humans can utilize echolocation within the lifetime of one individual, I can imagine it to be a pretty fast-evolving ability under the right circumstances.

In fact in every other tetrapod family, only 2 species of birds, the Oilbird and a species of Swiftlet bird, can echo locate and its not even close the quality of bat and cetacean abilities. Take a time to think about, birds are way more diverse than mammals, with more than 10.000 species worldwide and yet TWO evolved echolocation, this ability is insanely difficult to appear in non mammalian animals

24:14, As someone who can echo-locate, I can say that what you expect to locate and you can locate is extremely counterintuitive. So I think that's a big reason sighted people are handicapped. If there's a wall, you might not be able to locate it if there's a tree off to the side. Since sound is a wave, reflections from the tree intercept reflections from the wall. If you have vision, then it's unintuitive cause when the sight of the wall is unobstructed, it's hard to imagine that a tree to the side of the wall impacts what you hear. I can tell you something visually ignorable like the fluffiness of a carpet can make the sound profile of a room completely completely different

@@__--__ I‘m not an acoustics expert, and this is speculation, but I could imagine that you pick up on the left-right ear phase difference in the echo. A wall, if far enough away, will return a “flat” echo (approximately planar waves). The echo from a tree would preserve a spherical wavefront over larger distances. Meaning: your left and right ear hear different parts of the reflected wave at the same time. Perhaps your brain picks up on this phase contrast and ignores the flat “boring” echo from the wall as background noise. And the time delay between the echos might not be enough for you to separate them. Like I said, this is speculation, so take it with a grain of salt. In terms of physics, there are three major differences between sight and your echolocation: 1) sound wavelengths are comparable to the size of objects in our environment, so wave physics is more important. 2) we usually see the reflections of a more or less stable light source, while you hear the echo of a short, sharp transient (click). 3) light is so fast that it’s instantaneous for everyday purposes, while sound has a delay long enough for you to perceive. It would be interesting to learn how you perceive different echos like trees vs walls, if that can be described adequately in words.

Walls are very simple, (now get ready for the most incoherent explanation) Imagine everything's a mirror, but you can only see yourself. Like if a wall reflects up to the sky, you can't see it. So corners are very easy to see, since there's always an angle that will reflect back at you Trees are kinda weird, from a distance, you can hear them fine (a bit static-y), but once you're underneath them, it's like being covered by a blanket. If there's a wall in front of me and unobstructed, just being under a tree means I won't be able to hear it. By far the weirdest echoes are from corrugated surfaces tilted away from me. I hear a chirp, like a bullet ricochet or a bird... why?

There should probably be an entire series on every time plants 🌱 have evolved into trees 🌳🌲. They keep on doing it, even in lineages which are usually completely non-tree like. Orchids stand out as a major exception, as they are the second largest group of angiosperms, but have no trees (though a few shrubs). Likely because of their tiny seeds and the fact they often specialise in growing outside of the soil (e.g. on other plants or on rocks). (Some orchid-like-flower trees are called Orchid Trees but they are not orchids.) It would likely take multiple episodes just to get though the colossal number of cases. Another major episode/series could be every time photosynthesis has evolved. Most of the examples would be a protist, fungi or animal evolving to gain a photosynthesising endosymbiont, such as Symsagittifera roscoffensis.

Several things. First, you forgot hippos. There is a theory among certain zoologists that they are able to echolocate. Second, in 2019 I went blind for a year and a half and I practiced echolocation to a limited degree. It's hard to explain, and people have asked me how I did it but the best I could describe it was that you make a sharp noise and you can just sense where the sound bounces and while it's not precise, it does allow you to maneuver in your environment and locate items such as a glass of water. Personally I think all mammals carry the potential for echolocation but since our sight organs are the prominent sense we don't tend to use it instead focusing on the sense that provides us with the best layout of our surroundings. Just thoughts is all.

It seems to me that "echolocation" itself isn't rare or even a feature itself, but a by product of being able to hear and a behavior (a how to use that hearing, it is a brain pathway thing). If you can hear and derive some positional information from it, and if you can emit sounds that can bounce back to you from other objects, that is some form of echolocation. What is more rare is dedicated/priamry echolocation. That is, organisms focusing on and refining this behavior so that it can be a primary form of environmental navigation when used rather than complimentary to a much more dominant sense, or physically evolving body parts to allow additional forms of hearing/sound detection to further speciliazie in this behavior.

You should do compound eyes. They came and went and reappeared a few times. Giant tortoises were more common with 16 species in Victorian times, now.. 4? They might be all related. My aquarium fish (Congo rope fish) has legit snake scales by the look or it, scales, horns and otsteoderms would fill some time.. what about folding wings or gastralia. Venom still has curious beginnings in dinos, is that settled, convergent or some long dormant genes of a common ancestor? Any recent finds pushing venom grooves back again? Kinda unrelated is scorpion venom, they are tetraploidal (if that is 2 complete sets in every cell), that stuff is over 400 different peptides and aminoacids and whatever else compared to 100 or even 20 in snakes. What about nails? It is kinda odd if you think about it, that we didn't end-up with claws like 99% of every other critter to roam the earth. If a new edition of "Analysis of Vertebrate Structure" by Hildebrand exists, it might give you some comparisons to expand on also. My ed. is late 80's or 90's. Still good, but undoubtedly out of date in some places.

silk probably evolved only once since it is a very specific protein

Humans can be trained to echolocate as well, and the precision of human echolocation is spectacular. Probably all animals that are able to perceive directional sound in higher frequencies, have a basic ability, for this. it is just that some lineages specialized on this much more. Now, if we stretch the definition of echolocation to include tapping, humans do use it quite often to identify hollow structures, bad nuts and more.

It is very interesting that an Aye-aye, a creature with big ears,, that detects a creature by sound & presumably by feeling the insect vibrations on a branch as well can also echolocate as well. We know scorpions can detect prey moving with hairs on its legs. All this leads to very interesting questions. Do other insects beside moths use echolocation? Do moles and animals that have convergent evolved with moles use echolocation? Do elephant shrews use echolocation? Do elephants, Dugongs and mantees use ecolocation? If humans use echolocation to animals with big ears Bat-eared foxes, Fenders or Kit foxes use echolocation? What about Red foxes Servals, Artic foxes and Maned wolves?Wolves? What about some amphibians or lizards? The questions open up a Pandora's box of question. Does everything from fish on up have innate abilities of echolocation or a closely related skill?

The evolution of sight could also be interesting, if I recall correctly, squids evolved sight differently...

It's been done on other channels, but I'd like to see your spin on the whole "everything wants to be a crab" thing. You know, like how hermit crabs, king crabs, coconut crabs, etc. aren't really crabs, and why such a body plan co-evolved between crabs and anomura (false crabs).

Yeah I'd like his take on that one too. Lots of things end up looking like crabs,....and lots of things end up looking like worms.

Memes aside, the crab body shape has only evolved a few times, in groups so closely related they were probably halfway there already

How about creatures that evolved to specialize in movement involving jumping? Grasshoppers, frogs, kangaroos etc.? Might be something there and could be interesting. Great video as always! Edit: spelling

Video suggestion: vermification, every time animals became worms Basically when animals became elongated to be able to squeeze through thigh spaces(some molluscs, eels and other fish, caecilians and other amphibians, etc.). You could make either a section about ophidization(reptiles becoming snakes) or make a separate video for it.

This convergent evolution serie is already an awesome idea, but I would have never thought about doing something on echolocation, that is just pure delight

19:02, that's not restricted to shrews, unless I and one. I once when I was a kid navigated thru a glass maze in amusement park using high pitch short yell to figure out if the route is dead end or not. Didn't fail me even once. So that kind of "echolocation" only requires a good hearing and capability to produce short high pitch sound. It is pretty far from actual echolocation though, but I see why it could develop multiple times individually considering how easy the most primitive form of it is to do.

Indeed. I think it could be a argued that most if not all mammals have echolocation, If you define echolocation broadly enough (spatial navigation using sound, allowing obstacle detection without contact nor light). If you look at it like this, advanced echolocation is bound to happen for any mammal who need to move fast in places with no visibility, and it should evolve quite fast cause the base system is already in place.

maybe the visual cortex is more like spatial cortex, it just happens that we process spatial perception using visual information
