E Lau shows very nicely how bioluminescence in ostracods, fireflies and sea pansies can use very different structures yet convergently recruited homologous enzymes. The number of functional genes varies according to lineage-specific duplications. https://www.biorxiv.org/content/10.1101/2023.04.12.536614v1.abstract #SMBE2023 #ConvergentEvolution #paralog #bioluminescence

Carlos Cortez shows how a single mutation was sufficient to evolve Hb from a tetramer to a dimer. How does specificity of heterotetramer evolve? 2 deletions and 1 substitution in one of the 2 paralogs are sufficient. Overall, evolving heterotetramer complex from identical at birth paralogs is remarkably simple. #SMBE2023 #paralog #duplication
