Chronology of appearance of
opisthokonta,
metazoa (2),
eumetazoa (3),
bilateria (4),
protostomia,
Deuterostomia (5) and
chordates (6) based on the average of the results of molecular analysis of Peterson J. K. et al. (2008). Divergence between the colonial unicellular and multicellular members of filozoa (1) through innovation and development of cell
adhesion molecules,
immune complex systems and programmed
apoptosis.
Vertebrata (7),
Tetrapoda (8) and
amniote (9) based on fossil record of each group. In letters and "?" some problems of current zoology:
Urmetazoan problem (A),
Urbilateria (B) and the location of
acoelomorpha (C) based in Baguña (2004), Dunn et. al. (2008) and Philippe et. the (2011). Inclusion of ctenophores to problem of basal edges based on the molecular analysis of Dunn et. al. (2008)).
