Hesperornis the Dinosaur Era's Penguins

[@planescaped]

"Fossil evidence shows that the life of a Hesperonis was terrifyingly harsh and often short" So pretty much like most birds.

[@knoxw2491]

So are parrots weird? mines life expectancy is 25 but I’ve seen some with a life expectancy of 90 years.

[@jelofly5242]

A parrot in captivity isn’t really like “most birds.” Compared to birds in the wild, a pet parrot is definitely unusual in that it doesn’t typically have to worry about predation and starvation, which are probably the factors that drive bird life expectancies down the most.

[@Dragrath1]

@@jelofly5242 True but even excluding captive animals Parrots in the wild still do tend to still have long lives for animals of their size which is actually a general trend seen among most modern birds if the extremely high juvenile mortality is excluded. Thus while baby birds have extremely high mortality rates but if they manage to make it through the harsh learning curve many species live for a decade or more. The difference comes down to what definition of life expectancy one uses, mean life expectancy would give you a very short lifespan for example however maximum life expectancy would be much longer since birds like Parrots or Crows that make it through their Juvenile period often live many decades. This rule is much more general however as it can also be seen with primates(like humans prior to eliminating most forms of infant mortality) Sea turtles, bats, fish, snakes, salamanders etc.

[@theperfectbotsteve4916]

@@Dragrath1 Isn't there a trend that flying animals tend to live longer than flightless animals of the same size? Even the smallest bats live 10x longer than rats, I think.

I have to say, I love these new paleoartworks with feathered dinosaurs and colorful extinct animals! It is so much more realistic and beautiful! 😁

Accoring to current theories.... The feathers on dinos are the hot new pub quiz knowledge. Still a theory. And the colours are of course complete guesswork.

[@eliletts1680]

@@5Andysalive um, feathers have been confirmed on some dinosaurs...

[@amari6229]

@@5Andysalive pigment-indicative chemical patterns have actually been recovered in some fossils which can give a pretty solid idea of how they’d appear colour-wise. additionally on the more theoretical side theres the common paleodepictive approach of considering a single species environment habitat climate predation patterns etc and comparing them to animals now in similar environs and physicality, as colours are just as much evolutionary traits and developments as any other feature. and as the person above me said yes, there is tangible evidence that many species did indeed have feathers (perhaps not all, but certainly a large amount, I’d guess moreso than non-feathered) which can be realised in a number of ways, the most obvious being their imprints

[@afa78djd]

3:31 Maybe they did something similar to loons and Grebes that have to belly flop or walk awkwardly upright because their center of balance is so far back.

[@CJCroen1393]

I think that's how most paleontologists think Hesperornis moved on land, yes. Baptornis might have been able to walk though, albeit somewhat clumsily.

yes but hesperornis was bigger than a grown man

Actually, mammals were diverse too before the extinction. There was several clades cousins to monotremes, marsupials and placentarians prior to the extinction. It's just that most of them looked like little shrews 😅

I’m not sure how many niches pre Kt extinction birds filled but it seems MLM is on the money. If they all looked like shrews they probably occupied at least similar niches, since that body plan has a gimmick which is long term survival. So that’s one main niche. Meanwhile we have a pre KT bird that not only evolved to fly but then evolved to be aquatic afterwards. But yeah, it’s always amazing to think just how many little critters existed even from a glimpse on the record.

It's only so awful and harsh compared to our comparatively cushy lives. It's not all bad, and wild animals aren't constantly desperately fighting for their lives. The same way dinosaurs weren't fighting and killing eachother 24/7. Sometimes they just relaxed in the sun, sometimes they dug holes and kicked stickes around for fun, sometimes they play wrestled. Nature can be brutal, but it isn't always

[@Kavest]

Hey Moth! I love your videos and I've watched tons of them. I have a question though. Recently I've encountered many people who do not believe in evolution. They claim that there is no scientific theory of evolution and that there are no experiments that have proved evolution. How should I respond to this? What do you think are the best arguments and most convincing evidence in favor of evolution in such a situation?

[@niklassule-unofficial4200]

Show them a fossil

[@callusklaus2413]

Hey Kavest, it's really difficult to argue with these types because you'll find them not acting in good faith! If you want some really compelling arguments for evolution, I highly recommend The Greatest Show on Earth by Richard Dawkins. I find the man to be a goober elsewhere, but man can he write about evolution. Before you do that though, familiarize yourself with terms like "motivated reasoning" "confirmation bias" and "staw man fallacy". You're contending with people who have a religious/political interest in denying certain facts of the world to suit their purposes. Evolution for example is extremely problematic for a biblical literalist. The same is true for Islam and Jewish creation myths. If you want to learn more about this, I highly recommend you check out Genetically Modified Skeptic, Cognitive Dissonance Podcast, the books Greatest Show on Earth and The Selfish Gene. Lastly, if you want to watch something Carl Sagan's work is incredible, check out Cosmos with Carl Segan. Good luck on your journey my friend

[@dalkay]

Late but I’d show how dogs have changed over the last thousand years from human breeding and say evolution is like that but natural rather than guided by humans.
