Draw the cladogram for amphibians.
Draw the cladogram for reptiles.
Draw two cladograms, both showing the traits, and leave it as a hypothesis.

Creating cladograms involves showing the evolutionary relationships between different groups based on traits. Here are simplified steps to approach the task:
### Cladogram for Amphibians:
1. Start with the common ancestor of all tetrapods: This is at the base.
2. Branch off: One branch leads to amphibians, showing traits like moist skin and a dual life cycle (aquatic larvae to terrestrial adults).
### Cladogram for Reptiles:
1. Start with the common ancestor of amniotes: Again, this is at the base.
2. Branch off: One branch leads to reptiles, showcasing traits like shelled eggs and scaly skin which differentiate them from amphibians.
### Hypothetical Cladograms:
1. First Hypothetical Cladogram: Shows traits like lungs and dry skin as key differentiators.
2. Second Hypothetical Cladogram: Could involve different characteristics like presence of scales and ability to survive in drier environments.
### Cladograms with Scientists’ Votes:
1. First Voted Cladogram: May illustrate a different hypothesized relationship based on certain traits scientists prioritize.
2. Second Voted Cladogram: Shows another hypothesis, perhaps based on genetic data or fossil evidence.
### Explanation:
Cladograms are visual representations based on traits that indicate evolutionary relationships. Scientists often debate and vote on the most accurate representations, which can change with new discoveries or methodologies.
