@brothermine2292 4 года назад

No need for heat. If a "chicken egg" is defined as "an egg laid by a chicken" then a chicken must have existed before the first chicken egg. But if a "chicken egg" is defined as "an egg that will hatch into a chicken" (assuming it's a healthy egg kept warm and safe) then a chicken egg must have existed before the first chicken. In summary, a proto-chicken laid a mutated egg that hatched into the first chicken, and the question is whether that egg should be called a "chicken egg."

@@phynx1756 not exactly. Free will is simply the ability to choose and humans generally always have that choice. The concept of the "deterministic nature of cause and effect" is simply that all effects have a cause, that nothing is truly random. Anything is only seemingly random because we can't predict the effect of an action or circumstance, however with the more knowledge we gain, the more accurately we can predict things and the less random the world seems.

@krankarvolund7771 4 года назад

@Madalin Grama Hem, not exactly, current species of sharks can reproduce have the three ways of reproduction. The most "primitives" are ovipares and lay eggs they attach to rocks, most of the sharks are ovovivipare, which mean they are born fully formed, but grow in utero in a separate egg, and some sharks are vivipare. But what made mammals, or at least placental mammals so unique is not the viviparity, but the placenta. Sharks don't have placenta, even the vivipares ones, they have a vitelline sack, like of an egg, but connected to the mother and common to all the embryos. And guess what, the DNA from viuses concerns the placenta ^^

No, that's the mucus plug coming out of the cervix to prepare for the birth.

@socialdeviant13 4 года назад

Effectively. The mucus plug is a separate membrane from the amniotic sac. The mucus plug can detach without the "water break," but not the other way around, and the amniotic sac is a closer analogy to an eggshell, since it surrounds the fetus and keeps fluid inside.

I had no idea it was repurposed viral DNA, that's actually so cool. Really makes you wonder about the power that outside forces really had on evolution outside of just adapting to the environment

Wow! That was super interesting. I was always told in school that egg cells in mammals aren't like eggs from birds, just kind of similar in some ways.. but they are the same! But they just develop differently after fertilisation. It's really cool how interconnected everything is. So many things about us originated by chance, like all mammals having an inner ear bone must've originally been one creature that randomly had them, right? I know a lot about physics, and a little about chemistry, but far less about evolutionary biology.

I love that human whale and bat "hands" are all the same exact layout of bones just with different lengths

@ettinakitten5047 Год назад

Well, we label different things "eggs". The usage in birds would be more like calling a pregnant uterus an egg.

FINALLY! I've been requesting this episode for years. Thank you, Eons! HOWEVER, you're not done! I think you should delve even deeper and make an episode on invertebrate eggs as well. This episode only covered vertebrate egg evolution but the invertebrates we're the true mavericks having developed eggs long before any vertebrate was around :)

I have ALWAYS said that the Egg Came First, ever sense I was little and I first heard this nonsensical "riddle". The circular logic of "which came first" bugged me hard, and it felt like "But what laid the egg if it came first" was asking the wrong question... or even Begging the Question. Finally I said "Dinosaurs Laid Eggs, Therefore The Egg Came First!" ... rarely was the riddle bearer ever pleased with my answer.

@nicjohn60 3 года назад

Can I just say, echidnas are super cute in real life. Even though they're not related to hedgehogs, they sorta look similar and they do that adorable waddle. I'm lucky to see an echidna every so often when I go for a walk in the afternoon - wish I could take one home :) Australia has some really weird and wonderful life
