I saw a two-headed snake at my local county fair last year. It's weird. Do you think it's happening more now because of environmental pollution? It
might be a sign of more mutations in nature to come.
As a rule a manwife has two heads, if you really think about it. On a more serious note, I really don't know if the two headed snake thing is a
mutation due to pollution, or if it's a genetic mutation from something else. At any rate, they are pretty weird to see and apparently becoming more
common.
Its a birth defect, when the egg tries to separate into two (twins) but it doesn't quite make it... Siamese twins are a good example among humans,
but this happens in many different animals..., just that in animals, it usually keeps them from competing, and they die off, and never
propagate...therefore, it happens less often.......
