Our paper unpacking "fitness" is out doi.org/10.1093/gene.... How to define fitness depends on what question you ask. Selection acts on organismal vital rates, longer-term outcomes make sense for genetic lineages, models link them. "Invasion fitness" = speed, but sometimes probability matters more.

Why there are so many definitions of fitness in models
Abstract. Evolutionary “fitness” is operationalized in many different ways in models. Its role is to quantify that which is favored by natural selection. G

With Eugene Koonin, we propose a concept of “the selfish ribosome”, under which evolution of life is viewed as a ribosomal takeover, where the ribosome evolved to consume most of the cell’s resources, while other cellular componentry ensures the propagation of the ribosome. arxiv.org/abs/2602.23268

𝘐𝘮𝘢𝘨𝘪𝘯: an integrase-like gene conserved across malacostracan crustaceans derived from a Ginger1 DNA transposon We discovered a domesticated transposon in crustaceans, which has abandoned its mobility for a host function (likely reproductive). doi.org/10.1093/gbe/...
Figure 1. Imagin, a multi-exon integrase-like gene in malacostracan crustaceans. 
(A)	Structure of the PjImagin gene. The transcript is shown in light blue and the CDS in white. The YPYY motif is colored yellow, the H2C2 zinc finger is colored sky blue, the defunct DDE catalytic core is colored in pink, and the disordered region is shaded in gray. Gray vertical lines denote the positions of key residues denoted in panels C and D, with 
the last two lines being shaded to indicate the corresponding positions for the lost D and E residues (Panel E).  
(B)	The genomic context of PjImagin and orthologs. PjImagin is flanked by exons 14 and 15 of methylmalonyl-CoA mutase, mitochondrial-like (MMUT) gene, which runs on the opposite strand. Note that the Imagin gene of the swimming crab (Portunus trituberculatus) lies on an unrelated position. MMUT CDS is colored green, and MMUT exons corresponding to exons 14 and 15 of P. japonicus MMUT are connected with light green ribbons. CDS of other genes are shaded gray. 
(C)	Domain architectures of malacostracan Imagin proteins. The coloring scheme follows that of panel (A). 
(D)	Conservation of the YPYY motif and the H2C2 (HHCC) zinc-finger domain in integrase proteins. Species names are listed on the left, with protein accession numbers provided on the right. Entries Ginger1-1_HM, Ginger1-2_HM, and Ginger1-3_HM were adopted from (Bao et al. 2010). 
(E)	Loss of the DDE catalytic residues in crustacean Imagin proteins. Species names are listed on the left, with protein accession numbers provided on the right. Note that some residues may be missing from this alignment because regions containing long gaps were automatically suppressed by DALI. Each residue is shaded by background color according to the secondary structure assignments by DSSP: light green: loop; dark green: helix; blue: strand. Conserved aspartic acid (D) and glutamic acid (E) residues comprising the DDE motif are highlighted in black. 
Figure 3. Imagin is a domesticated Ginger1 DNA transposon. 
(A)	Maximum-likelihood phylogenetic tree of 121 DDE integrases and derivatives (136 sites; model: VT+R6).  
(B)	Subtree of (A) showing the phylogenetic relationships of Ginger1-like elements. The bar beside the tree indicates amino acid substitutions per site. The slashed values beside the nodes indicate the support values for the ultrafast bootstrap test followed by the SH-like approximate likelihood ratio test (1,000 trials each). Figure 2. Phylogenetic analysis of decapod Imagin proteins. 
A total of 463 sites were used for the maximum-likelihood phylogenetic analysis using IQTREE v3.0.1 (substitution model: Q.MAMMAL+F+I+G4). The slashed values beside the nodes indicate the support values for the ultrafast bootstrap test followed by the SH-like approximate likelihood ratio test (1,000 trials each). The bar indicates amino acid substitutions per site. Euphausiacea and Stomatopoda were used as the outgroup. Imagin proteins from brachyuran crabs formed a long branch relative to the other taxa, suggesting accelerated evolution following the translocation event in this lineage.

🚀 Released gbdraw v0.6.0! - Added dinucleotide skew plotting to linear mode. Fixed the bug where only GC skew could be drawn. - Added links to relevant sections of the documentation throughout the web app help menu. Try out:👉 gbdraw.streamlit.app
A grid of 12 circular E. coli  genome maps showing dinucleotide skew plots for GC, CG, AG, GA, CT, TC, TG, GT, CA, AC, AT, and TA. Each circle displays color-coded genome annotations (CDS, rRNA, tRNA, etc.) around the outer ring, with inner line plots showing positive and negative dinucleotide skew values.
Below the grid, a linear representation of two E. coli genomes shows annotated tracks, GC content, and GC skew plots, with two genomes linked with ribbons representing BLASTN hits. Note that the lower track (pathogenic strain O157:H7 Sakai) has multiple prophage insertions (shaded with orange) that are absent from the upper track (the laboratory strain K-12). Further below are five linear genome comparison diagrams of Hepatoplasmataceae mollicutes, each with colored gene annotations, GC content and GC skew plots, and gray ribbons indicating TBLASTX hits across genomes.
