- Phylogenetic Classification - OpenCurriculum
In the tree in Figure 2, species 1 and 2 shared a more recent common ancestor with each other than with species 3 Therefore, species 1 and 2 are more closely related to one another than to species 3
- The scaling of social interactions across animal species
Social animals self-organise to create groups to increase protection against predators and productivity One-to-one interactions are the building blocks of these emergent social structures and may
