A shared birthday would only have to happen once a year in these groups. Once a year or even once every few years could seem rare to you, but it still could fit the probability described.

Also, if you don't have the kids for all of the year (weekends, holidays, and summer) then it would decrease the odds of having one pair share a birthday and your being aware of it.

I'm guessing a bit here to give possibilities because I really know nothing about your samples.

Eve had a daughter, her daughter had a daughter, that daughter had a daughter...so on and so forth. From that string of daughters, your mother was born. She had three kids, none of which were daughters.

She is the first woman in that string of women to NOT have a daughter.

This is the simplest of all the facts listed to understand.

If you fold a piece of paper in half, it becomes two sheets thick. If you fold it in half again, it becomes 4 sheets thick. Three times, 8 sheets. If you fold it in half 42 times, it becomes about 4,398,046,511,000 sheets thick. Multiply that by the thickness of 1 sheet (about .004"), and you end up with about 277,000 miles. The moon is only about 239,000 miles away.

Everyone has the Eve thing only partially correct. The mitochondria in your cells have their own set of DNA distinct from the DNA in your cell nucleus. You inherit the DNA in your nucleus from both your mother and father. You inherit the DNA in your mitochondria only from your mother with no contribution from your father. So your mother inherited her mitochondrial DNA from only her mother, who it inherited it from only her mother, and so on until you get all the way back to Eve in a direct line with no contribution from any of the fathers. If the mother has only sons, none of the mother's sons will pass on any mitochondrial DNA, so the line is broken.

Edited because I had an error so it made no sense.

It's referring to the Dichotomy paradox, I believe.

Well that probability is that at least one pair of kids will share the same birthday. So if you work with a group of kids that size and there is at least one day with multiple birthdays, it fits the problem.

Yeah, if "rarely" means once a year, then the math checks out.

What if you pass point B up on the way to point C? Did you not cross point B?

Assume your mother only had sons. Your mother has a mother, meaning her mother (your grandmother) had a daughter. This means that your grandmother's mother had a daughter as well (your grandmother). This continues on.

Therefore, your mother is the only woman in her lineage not to have a daughter.


How do we know that one of the women 5 or 6 generations ago didn't have a daughter and a son? Just because a few generations of women keep having females doesn't mean there's been no males since Adam and Eve.

Edit: Nevermind, I misunderstood the main point. I get it now.
