No one knows. conjoined twins have been around as long as humans have, more than one million years.The first famous confirmed case of conjoined twins were Chang and Eng Bunker.
The old answer would have been Siamese twins. now they're simply called conjoined.
He is a neurosurgeon who has been involved in separation of several pairs of conjoined twins.
Conjoined twins are basically two beings made from the one egg or cell, and this egg has not broken apart properly, and so the twins have been fused together. They may share the same organs - like brain, shoulder, heart, leg...etc. Sometimes they are separated in order to be able to live separate lives.
Yes. Conjoined twins are always identical (monozygotic) twins, and identical twins are always the same sex.There is a theoretical case where identical twins could be opposite genders, when the babies are female but in one of the females, a branch of one X chromosome breaks away; however, I don't believe this has ever been observed.
Generally fraternal twins are more common. For fraternal twins to occur twins must diverge, but differentiate upon becoming separate entities. Identical twins are rarer, in which the two siblings are of the same gender and are exactly alike upon birth. Rarer so are conjoined, or "Siamese" twins. This occurs when twins are born partially or extremely fused together. There is only a 25% survival chance for a conjoined twin. Most were only connected by gristle and flesh, and could have been easily separated easily, were they in modern society.
Conjoined twins are identical but attached to each other and may share organs depending where they are attached to the others body. Conjoined twins are attached because the egg cells have not separated properly in the mothers womb.
Twins have been born since man has existed and it is difficult to know when the very first pair were born. The first documented twins were born in American in 945 A.D.
Yes
Elephants are herbivores, but human remains have been found on at least one documented occasion. The exact reason as to why an elephant would eat a human has not been proven.
There are many ways that conjoined twins can be connected. there have been some that were connected by a piece of skin, really any part of their body can be connected. The reason this happens is when two or more of the mothers eggs are fertilized, they can become connected, and than as they grow, they are stuck together.
