So, how did birds eggs get pointy, if they did?

Is the point of this question to disprove evolution or something? Because I doubt that it will. JMHO. People smarter than me will have to weigh in on the subject.

Whats the pointy?

Pointy ended eggs don’t roll out of the nest as easily.

Nice replys guys. Now I wondered. If there were three possible designs of an egg. One spherical, one pointy and one double-tapered, a point at either end. First, which might be produced most easily and efficiently. Second, which is most useful, on, lets say, a cliff ledge 800 feet high.
It is not so much the why as you already know but the how your egg be pointy.

The pointy shape results from the egg being pushed through the narrow oviduct. It’s produced when the oviduct muscles contract behind the egg to push it forward. Since the wall of the egg is still malleable, the pointy end develops at the back side. It’s squeezed through the oviduct, with the narrowest point occurring at the end of the egg.

Ah, the mystery becomes clearer. Do snakes turtles and tortoises have different muscles, as thir eggs appear to be spherical.

We should silence anyone who opposes the right to freedom of speech… ?
How about: Never say anything which doesn’t improve on silence.
Seriously, do you actually use words like “Doth” and “Thy”?
or is this just the case of another condescending anonymous troll who delights in stirring pointless debates up on a Catholic site?
What is the point you are trying to make?

I don’t know for sure. That’s a likely reason, or maybe their oviducts are shorter/wider, compared to a chicken’s.
As they say in the scientific community, “more research is indicated…”.

I never took the question that way. I thought it was a reference to Lewis Carroll’s “How doth the little crocodile…”
*How doth the little crocodile
Improve his shining tail,
And pour the waters of the Nile
On every golden scale!
How cheerfully he seems to grin
How neatly spreads his claws,
And welcomes little fishes in,
With gently smiling jaws! *

“Eggs come in 5 basic shapes;** round balls in owls and woodpeckers**; pyriform or top-shaped eggs like plovers, these are round eggs with one end looking quite pointed, this end is normally aimed in towards the enter of the nest; long are an adaptation to possessing a narrow pelvis, yet needing to lay a bigger egg. Long, thin eggs which are pointed at one end and thus tend to roll around in circles are a feature of cliff nesting species such as Guillemots. Finally, there is the ordinary oval egg, characterised by the common chicken egg. This is by far the most common form of egg.”
Do you see a differance? Round eggs, and long pointy eggs for cliff ledges. So how did the pointy egg get pointy for the Guillemot but not for the woodpecker? Are pointy eggs an adaptation or an accident. They might have been spherical but would have rolled of the cliff ledge.

I’m sure I’ve read them somewhere, perhaps it was Shakespeare - “Ope thou not thy ponderous marble jaws …” - Hamlet to Ophelia
This is philosophy room, the egg has a point, I’m sure…

Many eggs don’t really have a regular shape, they’re too soft and tiny. Shells, on the other hand, are a whole different ball game - round eggs for soccer, double-pointed for football and single-pointed for chickens, which didn’t come first.
Science forums are really good for answering thy homework questions.
The correct philosophical answer in this case, which I learned from my mom, is “because”, followed perchance by a swift clip to thy ear. :stretcher:

could the point on thy egg make it easier to start pushing out? I would think it would be much easier to pop out an egg starting with the pointed side and finishing with the round side. Maybe you could, like, write a paper over this issue or something hahaha

Thats an interesting point, I think someone said it was the roundy end which came out first not the pointy, but then in woodpeckers and owls both ends are round, you see.

I grew up on a farm. We had some ahem battery hens, so I got to see chickens lay eggs. And while the roundy end comes out first, I’ve actually seen the pointy end come out a few times.
Also, the most amazing egg related thing I ever saw, was an egg that came out with no shell, it was just an egg sack! And it was really tough, like we could throw it around like a hacky sack, it took a knife to puncture it.
And a fun fact, the Kiwi lays the largest egg in comparision to its body. the egg is 25% the size of the kiwi’s body!

I used to help pluck and gut our chickens, and it was fascinating to find the eggs in all the different stages, still inside the chicken. I wonder why the egg you mentioned was laid so early? Maybe it was scared out of her!

Is the egg fully hard after it is laid?
