ecoli Posted January 19, 2007 Share Posted January 19, 2007 I find it difficult to manage one brain... let alone two. I wonder if this happened to a human, would they have two separate concioussnesses. Link to comment Share on other sites More sharing options...
Bluenoise Posted January 20, 2007 Share Posted January 20, 2007 Yes two seperate concioussnessess. It's ultra rare in humans. But there is a living example in the states now. http://www.geocities.com/heldenkline/Hensel.html http://en.wikipedia.org/wiki/Abigail_and_Brittany_Hensel Link to comment Share on other sites More sharing options...
Mokele Posted January 20, 2007 Share Posted January 20, 2007 Actually, two-headed reptiles are a common birth defect, usually caused by improper incubation temperatures or mold on the eggs. This is basically just proof that ancient reptiles were just as susceptible. Mokele Link to comment Share on other sites More sharing options...
Dan Posted January 29, 2007 Share Posted January 29, 2007 I saw something on TV ages ago about a two headed tortoise(turtle in america). I think this is the same one... http://news.bbc.co.uk/1/hi/uk/4006351.stm Link to comment Share on other sites More sharing options...
lucaspa Posted February 7, 2007 Share Posted February 7, 2007 I find it difficult to manage one brain... let alone two. I wonder if this happened to a human, would they have two separate concioussnesses. Talk to a Siamese twin and find out! Two brains, remember? From the article "It is the oldest known reptile to suffer from a birth defect known as axial bifurcation. This happens when an embryo is damaged, and some body parts develop twice." Too much retinoic acid at the wrong time during development is one way to do this. So this is not a species, but a birth defect within a species.
