Thank you for the opportunity to help you with your question!
Sympatric speciation is an evolutionary process that drives this type of division between species that occupy the same habitat.
adaptive radiation is a process in which organisms diversify rapidly into a multitude of new forms, particularly when a change in the environment makes new resources available, creates new challenges, or opens new environmental niches.
Phyletic gradualism is a model of evolution which theorizes that most speciation is slow, uniform and gradual.
Punctuated equilibriumis a theory in evolutionary biology which proposes that once species appear in the fossil record they will become stable, showing little net evolutionary change for most of their geological history.
Taxonomy is the practice and science of classification. It is the branch of science concerned with classification, especially of organisms; systematics
Phylogeneticsis the evolutionary branching process may be depicted as a phylogenetic tree, and the place of each of the various organisms on the tree is based on a hypothesis about the sequence in which evolutionary branching events occurred.
