AI Thread Summary
The discussion centers around the rare medical phenomenon known as "fetus in fetu," where a fetus develops inside the body of its twin, often resembling a parasitic entity. A specific case is highlighted where an individual unknowingly carried a twin sibling for 36 years, leading to significant abdominal enlargement. The discussion reveals that the parasitic twin can exhibit various features, such as hair and limbs, but typically lacks a fully formed head and brain. Participants express curiosity about the consciousness of such a twin and the developmental stages at which this phenomenon can occur. The conversation also touches on related cases, including a documentary about conjoined twins with shared bodily structures, prompting inquiries about their shared experiences. A technical reference to the condition is provided, emphasizing its rarity and complexity.

OK, I really hate to loose the nice story I just wrote and having to rewrite it.. Greg really has to do something about that

In short: there was this guy that carried his twin sibling around in his belly for 36 years without ever knowing it until a surgeon opened him up to releave him from his 2-3 times 9 mo. pregnancy sized belly. Apparently the unborn fetus was a parasite and had been growing along with the adult as he grew

There are about 80 other reported cases of fetus-in-fetu :S

Woah! Was his sibling conscious?

It might have been if it wasn't calcified and headless. It had 26 pounds of hair, though. I don't really want to think about where.
 
Yes, it didn't have a well formed head but it did have a lot of hear and was quite big so it should have been alive for a long time I guess .

I had never heard of anything like this before, as I understand it the other fetus had actually implantated itself in the other person? Since it had its own sack with fluid and was able to grow.. anyone an idea at what point in the development of the fetus the window is for this to occur?

Just today I saw a documentary of a siamese twin which was one up to the shoulder but had two heads but seemed healthy otherwise.. I didn't see the beginning and I wonder how they experience sharing two brains with one body?
 
Hmm, I don't suppose you have an on-line reference, do you?
 
the technical term is called "Fetus in Fetu." normally the "parasite" child attaches itself to an artery but rarely does it actually form a face or brain. it does however, in some cases, form legs, arms, teeth and hair. here are some pictures:

Thread 'I need help understanding this quote about recent Natural Selection'

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...
