The first chicken was created from a mutation of another species. That mutation occurred before the egg was completely formed, making it the first chicken egg. The first chicken wasn’t born until it hatched from that egg.
Therefore, there was a chicken egg before there was a chicken.
But is chicken-ness actually defined by genetics? An important characteristic of a chicken is its domesticated status, if you consider the birds they descend from, they are remarkably similar, and it's hard to imagine that any one mutation would have been what caused people to start calling them by their own name or considering them as a separate species. It's possible that the first chicken became the first chicken when it was captured by humans, and so preceded the first chicken egg.
Yup. The domesticated chicken has changed quite a bit since domestication began, but the species is still a domesticated chicken (Gallus gallus domesticus). The primary ancestor of the domestic chicken, the red junglefowl (Gallus gallus), birthed the first domesticated chicken between 7,000-10,000 years ago.
I give people that can pull of casual sex like this a lot of credit. I'm not old fashioned, I'd just be anxious as heck about an intimate moment being one of the only things I'm being judged upon by another person. It's such a hard thing to practice and be truly good at (it's inherently awkward, and porn certainly doesn't count as practice). It's a joke, but comments like this just make it feel almost like a competition. I'd feel like I was taking a big exam or on stage without a rehearsal.
If I don't feel like I can have a good mutual laugh during, I'm not interested. Not many people I personally can achieve that kind of chemistry with in one night.
