Phylogenetic Analyses Allow Us to Examine Whether Cooperative Behavior

Phylogenetic analyses allow us to examine whether cooperative behavior:

A) is under the control of genes that follow Mendel's law of segregation.
B) is a fixed trait that can no longer be subject to natural selection.
C) will evolve in the future due to each species inhabiting similar environments.
D) can be explained by common ancestry rather than independent selection regimes.
E) can be subject to rigorous mathematical treatments.
