Chicken or the Egg?

obviously EGGS existed before CHICKENS did, since reptiles lay eggs.

the question would be more interesting if it were "chicken or chicken egg"
 
If you're religious, then it was the chicken that came first, as God created the chicken, and then that chicken laid the first chicken egg.

If you're not religious, then it was the egg that came first, as the first modern chicken was born from an egg that was laid by a slightly less evolved chicken (and therefore not a 'chicken' as defined in the question).

 
In speciation, genetic changes eventually lead to the creation of a new species from an existing one. The first 'chicken' was hatched from an egg laid by its parent. Its parent was a chicken-like animal, but just on the other side of the species line.

that's a really simplistic look at it, but that's the gist of things.

Do you suppose the same will happen with homo sapiens in the future?

Of course. Or more to the point, it is happening. Constantly. Speciation happens fastest with geographical isolation, but it's not neccessary. There was a recent study of some birds in (I think) China that found that the (related) species varied accross a large geographical area even without isolation. Distance and drift were enough. Distance in time would have to act similarly. Eventually, even if future Homo Sapiens looks not dissimilar from us, we may not be able to successfully cross-breed (if we could somehow move forward in time.)

That does explain the "different types" of humans out there, for lack of a better term
 
could maybe this "chicken-like" animal that laid an egg, that hatched a chicken, not even lay an egg at all? maybe the chicken developed the "egg-having" ability in it's later years?

It could go either way. Separation of species depends on whether they are genetically compatible (i.e. if they managed to mate, would they conceive). So if this first "chicken-like" animal were to be genetically compatible with the child it bore after it hatched from an egg, it'd be a "chicken". On the other hand, it could very well have not been compatible, we'll never know.

Are you suggesting that chickens independently developed egg-having ability parallel to the rest of birds developing the ability (or rather, the pre-chicken lost the ability to lay eggs, the first chicken was born live, then suddenly it re-developed the ability to lay eggs like all the other birds??!)
 
Ok watch out inflamatory question coming up....

So isolation is possibly why Blacks/White/Asians look so different...i.e facial features, hair length/texture, body size/shape etc etc... We are all the same race i.e Homo sapien but isolation/different conditions for generations has made us develop slightly differently....

Not racist...just clarifying ....I like biology...
 
Agreed with Isolation has affected the cosmetic changes we see....but I doubt there will be any major changes to the evolution of homosapiens unless some catastrophy occurs.

The Human Race is "successful" therefore it has no real reason to change as a whole. This can be seen in many other species....just look at insects. They live in the millions....why change?

Possibly if/when humans move off planet...those will be forced to adapt to their new surroundings.

BTW, IMHO....some reptile thingy laid the chicken egg

Permission to use that as my answer to people that ask me this dumb question from now on?
 
I read somewhere that humans might be evolving right now. The study was talking about how girls are starting to go through puberty at an earlier age. This was a couple years ago that I read this, so they might of changed it, I don't know. Its cool because everyone thinks evolution in humans means they are going to get another finger or something but really it could be many small changes over a very long period of time such as thousands of years. Like with the chicken egg it might not of been a hard egg to begin with it might of been just a soft membrane sack. So maybe everything is evolving right now but we just don't know it until we look at the time period from a big or smaller scope, which everone works best.
Sorry if this got off topic I just felt like it would be nice to say.
