- BiologyInternational Journal of Astrobiology

New sequence data indicate that choanoflagellates are a monophyletic rather than a paraphyletic assemblage that independently gave rise to animals and fungi as suggested by some authors and the nucleariid filose amoebae are the likely sister group to Fungi.

It is demonstrated that variable rates of evolution among lineages, sensitivity of the analyses to taxon selection, and conflicts in the phylogenetic signal contained in different amino acid sequences obscure the phylogenetically associations among the early branching Metazoa.

This chapter describes how the sequencing of the genomes of multiple protists phylogenetically related to animals and the study of the biology of these species are illuminating the emergence of metazoans and shows that recent data support a scenario with a complex unicellular ancestor of all animals.

It is shown that the choanoflagellates are the closest relatives of the Metazoa, followed by the Capsaspora and Ichthyosporea lineages, although the branching order between the latter 2 groups remains unclear.

It is proposed that the acquisition of these metazoan-specific developmental systems and the co-option of pre-existing genes drove the evolutionary transition from unicellular protists to metazoans.

It is suggested that any further testing of the legitimacy of this taxon should, at the least, include data from opisthokont protists, and the results underline the critical position of these "animal-fungal allies" with respect to the origin and early evolution of animals and fungi.
Molecular phylogeny of choanoflagellates, the sister group to Metazoa
- Biology, Environmental ScienceProceedings of the National Academy of Sciences

Four genes from a broad sampling of the morphological diversity of choanoflagellates including most species currently available in culture are sequenced, rejecting much of the traditional taxonomy of the group.

It is found that this enigmatic pathogen of humans and animals clusters with a novel group of fish parasites referred to as the DRIP clade, near the animal-fungal divergence, and is proposed to name this monophyletic clade Mesomycetozoa to reflect the group’s phylogenetic association within the Eucarya.

It is found that analyses of four conserved proteins from a unicellular choanoflagellate, Monosiga brevicollis, provide robust support for a close relationship between choan oflageLLates and Metazoa, suggesting that comparison of the complement of expressed genes from choano- animals may be informative concerning the early evolution of metazoan genomes.
