Question

So what did actually come first, the chicken or the egg?

In: Biology

Answer 1

The egg.

Dinosaurs were laying eggs long before there were chickens.

If you mean *chicken* eggs, then probably also the egg. Chickens evolved from a prior organism by mutation. That means that something that wasn’t exactly a chicken laid an egg with mutated DNA that we’d call a chicken. It’s not a hard cut, evolution is slow and gradual, but however you draw the line there was an organism before the line that laid an egg with something with DNA after the line.
