SP hybridization occurs when one s orbital and one p orbital from the same atom combine to form two new orbitals of equal energy. These new orbitals are linearly oriented 180 degrees apart, leading to ...

Hybridization is an important evolutionary mechanism in plants and has been increasingly documented in animals. Difficulty in reconstruction of reticulate evolution, however, has been a longstanding ...

‘Hybrid speciation’ implies that hybridization has had a principal role in the origin of a new species. The definition applies cleanly to hybrid species that have doubled their chromosome number ...
