The Closest Unicellular Relatives of Animals
Molecular phylogenies support a common ancestry between animals (Metazoa) and Fungi, but the evolutionary descent of the Metazoa from single-celled eukaryotes (protists) and the nature and taxonomic affiliation of these ancestral protists remain elusive. We addressed this question by sequencing complete mitochondrial genomes from taxonomically diverse protists to generate a large body of molecu...
متن کاملUnique mitochondrial genome architecture in unicellular relatives of animals.
Animal mtDNAs are typically small (approximately 16 kbp), circular-mapping molecules that encode 37 or fewer tightly packed genes. Here we investigate whether similarly compact mitochondrial genomes are also present in the closest unicellular relatives of animals, i.e., choanoflagellate and ichthyosporean protists. We find that the gene content and architecture of the mitochondrial genomes of t...
متن کاملDynamics of genomic innovation in the unicellular ancestry of animals
Which genomic innovations underpinned the origin of multicellular animals is still an open debate. Here, we investigate this question by reconstructing the genome architecture and gene family diversity of ancestral premetazoans, aiming to date the emergence of animal-like traits. Our comparative analysis involves genomes from animals and their closest unicellular relatives (the Holozoa), includ...
متن کاملThe Capsaspora genome reveals a complex unicellular prehistory of animals
To reconstruct the evolutionary origin of multicellular animals from their unicellular ancestors, the genome sequences of diverse unicellular relatives are essential. However, only the genome of the choanoflagellate Monosiga brevicollis has been reported to date. Here we completely sequence the genome of the filasterean Capsaspora owczarzaki, the closest known unicellular relative of metazoans ...
