The fundamental questions regarding genetic mutations are explored in relationship to natural selection and evolutionary drift (in which the frequency of gene variations shifts over generations) and in regard to parallel evolution (thus comparing and contrasting lineages that diverged in the past from a common ancestor), noting variously that mutation is random and adaptation is probabilistic.

Parallel evolution, Moroz proposed: While other branches of the animal family tree shared one path, the comb jellies essentially went down another street as they developed circuits of neurons, nerve cells that control such functions as motion and behavior.
The findings suggest that the parallel evolution of two-legged locomotion and manual dexterity in hands and fingers in the human lineage were a consequence of adaptive pressures on ancestral quadrupeds for balance control by foot digits while retaining the critical capability for fine finger specialization.

Author Michael Witgen uses this framework to analyze the parallel evolution and convergence of two social worlds: a Native New World and an Atlantic New World that resulted from Native-European encounters in North America.
As there are many species along the human line in the intervals since those separations that do not have anything remotely resembling human, bird or whale "language", I think these must be considered cases of parallel evolution of communication systems and not evolutionary precursors of human language with its unique richness and variety of symbols (vocabulary, syntax) and speed of their production.
Among topics are Elton as neither founder nor siren but prophet, parallel evolution in invasion ecology and restoration ecology, the conceptual threads of biodiversity as a bulwark against invasion, expanding the propagule pressure concept to understand the impact of biological invasions, 50 years of increasing research and decreasing control of cheatgrass, and responses of invasive species to a changing climate and atmosphere.
