Unlike Egyptian mummies, these don't have squishy bits preserved, but the rock around these carcasses had clay capturing texture of scales, a midline crest w/ keratin spikes, &, brand new, feet w/ hooves! 🧪⚒️🦕🦖 www.science.org/doi/10.1126/...

- Reposted by Daniel Ortiz-Barrientosalignments are mosaics of autocorrelated genealogies... nearby bases share ancestry until recombination alters the local tree. We derived the distributions of waiting distances for tree-change and topology-change events, extending prior single-population results to arbitrary species tree models.
- Reposted by Daniel Ortiz-BarrientosHybridization and introgression are major evolutionary processes. Since the 1940s, the prevailing view has been that they shape plants far more than animals. In our new study (www.science.org/doi/10.1126/... ), we find the opposite: animals exchange genes more, and for longer, than plants

- Excited to share our new paper in @GeneticsGSA ! We developed "Retriever," a novel method that enables high-quality genotype imputation in non-model organisms. 🧬 Congratulations to Charles on his first PhD paper! Paper: doi.org/10.1093/gene... A thread 🧵👇
- The problem: Genomic datasets, especially from next-gen sequencing, are often full of holes (missing genotypes). We can "impute" or infer this missing information, which is crucial for downstream analyses like GWAS. This process dramatically increases statistical power.

The Science History Institute in Philadelphia has acquired a huge archive of correspondence and other scientific material from the pioneers of molecular biology (Franklin, Klug, Perutz, Delbrück etc, with items from Crick and Watson, too). 1/n

- Reposted by Daniel Ortiz-Barrientoswoah this is genuinely, utterly WILD Ant queens of one species produce males of another species, so she can then mate with them and produce hybrid workers! This is so gloriously weird I can't quite compute it 🤯🧪🐜 www.nature.com/articles/d41...

- We’ve just published a paper on Senecio showing that ecological speciation and mutation-order speciation can act together rather than as an either/or. Congratulations, Maddie James and MC Melo!
- System: coastal Senecio lautus with repeated “Dune” (erect) and “Headland” (prostrate) ecotypes along Australia’s coast. Multiple parapatric pairs let us test selection’s role with natural replication.

We are gathering info on how DToL genomes are used. It will help us raise money to continue producing publicly available high-quality genomes.
