draw an evolutionarily accurate phylogenetic tree with the 5 lineages of Amniotes shown in the top figure, but with a different arrangement. You can exclude lungfishes and amphibians but include all other lineages. You can do this by swiveling the branches.

Transcribed Image Text:The image is a phylogenetic tree diagram illustrating the evolutionary relationships among different groups of vertebrates. It highlights three major evolutionary developments: digit-bearing limbs, amnion, and feathers. Each branch point is numbered and corresponds to the acquisition of specific traits:
1. **Base of Tree**: Represents the common ancestor of all depicted groups.
2. **Digit-Bearing Limbs**: This trait marks the divergence of amphibians from the other groups.
3. **Amnion**: A protective membrane that leads to a further split, separating mammals and reptiles from amphibians.
4. **Reptilian Lineage Point**: Splitting into separate lineages:
- **Lizards and Snakes**
- **Crocodiles**
5. **Feathers**: This trait is shared by the bird lineage and marks the divergence of the avian groups.
6. **Avian Lineage**: Includes:
- **Ostriches**
- **Hawks and other birds**
Each branch shows evolutionary pathways with corresponding images of representative animals, such as a frog for amphibians, a wolf for mammals, an ostrich, hawk, crocodile, lizard, snake, and lungfish. The tree provides insights into how these animals are related through shared evolutionary history.
