cladogenesis (klad-uh-JEN-i-sis) noun
The evolutionary change and diversification resulting from the branching
off of new species from common ancestral lineages.
[Greek klados, branch + -genesis.]
"If the branching pattern of a species tree reflects the evolutionary
relationships among its tips, then this pattern offers clues to the
process of cladogenesis and lineage diversification."
Arne Oyvind Mooers, Tree balance and tree completeness, Evolution,
Apr 1995.
