phylogenesis
Evolutionary lineage history
Phylogenesis is the evolutionary development and diversification of a species or group of organisms over time.
The term appears in biology when tracing how lineages branch and change across generations: The phylogenesis of whales shows their descent from land mammals.
Also called phylogeny.
