Which pattern is evidence that reptiles and amphibians share the same ancestor would it be they have similar skin they have legs they have eyes and they have back bones
The pattern that provides evidence for reptiles and amphibians sharing the same ancestor is the presence of backbones or vertebrates. Both reptiles and amphibians belong to the same larger group of animals called vertebrates, which are characterized by having a backbone or spinal column. This similarity in skeletal structure suggests a common ancestor from which both reptiles and amphibians evolved. The other traits mentioned (similar skin, legs, and eyes) may also provide additional evidence of a shared ancestry but are not solely unique to reptiles and amphibians.
