Why are reptiles and amphibalins born with extra body parts?

Question

Like 2 heads, 2 tails, a leg in the mouth an extra leg or eye. it's weird

Answer 1

Out of two main reasons
A natural reasons
there were twins one died in utero/egg and aborpt the other twin or as the egg divided into twins it happened to late and it split incomplete.
also the egg might have split uneven and thats why it got extra limbs from the other twin(who more than likely died, because he didnt get enough in the split.
b un natural reasons
the animal lives in a enviroment where a lot of toxins are./ those toxins , disturb the cell develpment and cause extra limbs and other bodily deformities like split gender and such

Answer 2

a lot of human beings are born with better physique factors and don't even are conscious of it. My spouse had an Xray some years decrease back to envision out a lump in her neck and that they stumbled on she had one extra rib. If I had the alternative i'd have one extra coronary heart.

Answer 3

that can happen in any animal, its just more noticable and more common in reptiles and amphibalins b/c they react faster to w/e pathogens that are in the envirment (cause their smaller) that may do damage to thier DNA and chromosones causing the deformity.
Also w/ frogs thier is a parasite that can enter the frogs body as a tapole and cause it to grow extra amouts and deformed legs

Incubation problems... Not having accuate temperatures or humidity. Jostling of the eggs. Improper health of the female when she was forming the eggs.
