Without the cladogram, it's difficult to provide an accurate answer. However, based on general knowledge of evolution, the ancestral trait for salamanders, lizards, tigers, gorillas, and humans would likely be the presence of jaws. This is because jaws are a feature that evolved early in the vertebrate lineage, before the divergence of the specific groups mentioned.

Here's a step-by-step reasoning:

1. Bipedalism: This is not an ancestral trait for all these animals. Bipedalism is primarily a characteristic of humans among the animals listed.

2. Amniotic membrane: While the amniotic membrane is a significant evolutionary adaptation, it's not present in salamanders which are amphibians.

3. Jaws: All of these animals have jaws, which is a feature that evolved early in the vertebrate lineage, before the divergence of these groups.

4. Tail loss: This is not an ancestral trait for all these animals. While humans and gorillas have lost their tails through evolution, salamanders, lizards, and tigers still have theirs.

So, based on this reasoning, the answer would be "Jaws". However, please refer to your cladogram for the most accurate answer.
