comment Which (naturally selected) evolutionary process led to the development of egg-laying?
Can you edit your question to to be less about the chicken-egg problem and more specifically about the evolution of egg laying? In what group of animals are you wondering about? The answer for most will be "they inherited it from their ancestors".

comment What kind of skull is this?
The top of the synsacrum in the loon isn't flat enough to be a good match. I know that loons have strange pelves, so that was my best guess. Whatever it is, it was a very large bird.
