Uncertainty in the Timing of Origin of Animals and the Limits of Precision in Molecular Timescales [PDF]
, 2015 The timing of divergences among metazoan lineages is integral to understanding the processes of animal evolution, placing the biological events of species divergences into the correct geological timeframe.

Genomic data do not support comb jellies as the sister group to all other animals [PDF]
, 2015 Understanding how complex traits, such as epithelia, nervous systems, muscles, or guts, originated depends on a well-supported hypothesis about the phylogenetic relationships among major animal lineages.

Evo-devo of non-bilaterian animals
Genetics and Molecular Biology, 2015 The non-bilaterian animals comprise organisms in the phyla Porifera, Cnidaria, Ctenophora and Placozoa. These early-diverging phyla are pivotal to understanding the evolution of bilaterian animals.

Trichoplax, the simplest known animal, contains an estrogen-related receptor: Implications for the evolution of vertebrate and invertebrate estrogen receptors [PDF]
, 2008 Although, as their names imply, vertebrate and invertebrate estrogen receptors [ERs] and estrogen-related receptors [ERRs] are related transcription factors, their evolutionary relationships to each other are not fully understood.

Animal Evolution: Looking for the First Nervous System [PDF]
, 2014 SummaryThe human brain is easily the most baffling bit of biology on the planet. How did the nervous system evolve? What came first: neurons or synaptic proteins?

Rotiferan Hox genes give new insights into the evolution of metazoan bodyplans [PDF]
, 2017 The phylum Rotifera consists of minuscule, nonsegmented animals with a unique body plan and an unresolved phylogenetic position. The presence of pharyngeal articulated jaws supports an inclusion in Gnathifera nested in the Spiralia.
