evolution of species New research suggests horizontal gene transfer between different species is a major driver of evolution.

In biology, a species is the basic unit of classification and a taxonomic rank, presumed evolution of five species of greenish warblers around himalayas. Evolution often happens in tandem a predator evolves an improved hunting method, and any mutations in the prey species that aid survivability will be selected for leading to a change in the prey population.
