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.

@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 ^^

chicken or egg, not chicken or chicken egg, knew this since I was 8. The first chicken came from an egg with a mutation. Delicious.

@rickkhan284 3 жыл бұрын

I can't get over this fact. I always thought it was some chicken ancestor which had evolved to lay egg.

Great episode. Of course, the "bill" of the Platypus is really unlike that of a duck because it is not hard, but soft and electro-receptive. That's how they find their favor food "Yabbies" in river or pond water that can be muddy. This is a very interesting episode, and finally (to my satisfaction at least) definitively answers the age old chicken or egg question.

What an outstanding series of documentaries PBS Eons make, and all the people who present it so finger-tip knowledgeable and able to say those complex names one after the other as though they were only saying: "make mine a ham sandwich", or whatever... though in my mind, I see all of them practicing in front of the bathroom mirror until they're syllable perfect, repeating those names (like saying:"red lorry; yellow lorry"!) until their jaw muscles ache, the sounds no longer make any sense after so many repetitions, and everybody else at home is late for work or school! Ha Ha! Keep making these great documentaries! Your enthusiasm is contagious and it is fascinating!

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 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.
