The genetic core of the universal ancestor
WebThe core set of genes, as represented by the red bar, identified as common to both wing patterns may be a representation of an ancient ‘melanism’ module that was used in both patterns to produce melanin pigments or an ancient ‘wing patterning’ module that has been used repeatedly amongst butterfly species to organise the formation of patterns on the … Web25 Jul 2016 · We investigated all clusters and phylogenetic trees for 6.1 million protein coding genes from sequenced prokaryotic genomes in order to reconstruct the microbial ecology of LUCA. Among 286,514 protein clusters, we identified 355 protein families (∼0.1%) that trace to LUCA by phylogenetic criteria.
